Travels in Alaska
by John Muir
Chapter X
The Discovery of Glacier Bay
From here, on October 24, we set sail for Guide Charley's ice-mountains.
The handle of our heaviest axe was cracked, and as Charley declared
that there was no firewood to be had in the big ice-mountain bay,
we would have to load the canoe with a store for cooking at an
island out in the Strait a few miles from the village. We were
therefore anxious to buy or trade for a good sound axe in exchange
for our broken one. Good axes are rare in rocky Alaska. Soon or
late an unlucky stroke on a stone concealed in moss spoils the
edge. Finally one in almost perfect condition was offered by a
young Hoona for our broken-handled one and a half-dollar
to boot; but when the broken axe and money were given he promptly
demanded an additional twenty-five cents' worth of tobacco.
The tobacco was given him, then he required a half-dollar's
worth more of tobacco, which was also given; but when he still
demanded something more, Charley's patience gave way and we sailed
in the same condition as to axes as when we arrived. This was
the only contemptible commercial affair we encountered among these
Alaskan Indians.
We reached the wooded island about one o'clock, made coffee, took
on a store of wood, and set sail direct for the icy country, finding
it very hard indeed
to believe the woodless part of Charley's
description of the Icy Bay, so heavily and uniformly are all the
shores forested wherever we had been. In this view we were joined
by John, Kadachan, and Toyatte, none of them on all their lifelong
canoe travels having ever seen a woodless country.
We held a northwesterly course until long after dark, when we
reached a small inlet that sets in near the mouth of Glacier Bay,
on the west side. Here we made a cold camp on a desolate snow-covered
beach in stormy sleet and darkness. At daybreak I looked eagerly
in every direction to learn what kind of place we were in; but
gloomy rain-clouds covered the mountains, and I could see
nothing that would give me a clue, while Vancouver's chart, hitherto
a faithful guide, here failed us altogether. Nevertheless, we
made haste to be off; and fortunately, for just as we were leaving
the shore, a faint smoke was seen across the inlet, toward which
Charley, who now seemed lost, gladly steered. Our sudden appearance
so early that gray morning had evidently alarmed our neighbors,
for as soon as we were within hailing distance an Indian with
his face blackened fired a shot over our heads, and in a blunt,
bellowing voice roared, "Who are you?"
Our interpreter shouted, "Friends and the Fort Wrangell missionary."
Then men, women, and children swarmed out of the hut, and awaited
our approach on the beach. One of the hunters having brought his
gun with him, Kadachan sternly rebuked him, asking with superb
indignation whether he was not ashamed to meet a missionary
with a gun in his hands. Friendly relations, however, were speedily
established, and as a cold rain was falling, they invited us to
enter their hut. It seemed very small and was jammed full of oily
boxes and bundles; nevertheless, twenty-one persons man aged
to find shelter in it about a smoky fire. Our hosts proved to
be Hoona seal-hunters laying in their winter stores of meat
and skins. The packed hut was passably well ventilated, but its
heavy, meaty smells were not the same to our noses as those we
were accustomed to in the sprucy nooks of the evergreen woods.
The circle of black eyes peering at us through a fog of reek and
smoke made a novel picture. We were glad, however, to get within
reach of information, and of course asked many questions concerning
the ice-mountains and the strange bay, to most of which our
inquisitive Hoona friends replied with counter questions as to
our object in coming to such a place, especially so late in the
year. They had heard of Mr. Young and his work at Fort Wrangell,
but could not understand what a missionary could be doing in such
a place as this. Was he going to preach to the seals and gulls,
they asked, or to the ice-mountains? And could they take
his word? Then John explained that only the friend of the missionary
was seeking ice mountains, that Mr. Young had already preached
many good words in the villages we had visited, their own among
the others, that our hearts were good and every Indian was our
friend. Then we gave them a little rice, sugar, tea, and tobacco,
after which they
began to gain confidence and to speak freely.
They told us that the big bay was called by them Sit-a-da-kay,
or Ice Bay; that there were many large ice-mountains in it, but
no gold-mines; and that the ice-mountain they knew best
was at the head of the bay, where most of the seals were found.
Notwithstanding the rain, I was anxious to push on and grope our
way beneath the clouds as best we could, in case worse weather
should come; but Charley was ill at ease, and wanted one of the
seal-hunters to go with us, for the place was much changed.
I promised to pay well for a guide, and in order to lighten the
canoe proposed to leave most of our heavy stores in the hut until
our return. After a long consultation one of them consented to
go. His wife got ready his blanket and a piece of cedar matting
for his bed, and some provisions--mostly dried salmon, and seal
sausage made of strips of lean meat plaited around a core of fat.
She followed us to the beach, and just as we were pushing off
said with a pretty smile, "It is my husband that you are
taking away. See that you bring him back."
We got under way about 10 A.M.
The wind was in our favor, but
a cold rain pelted us, and we could see but little of the dreary,
treeless wilderness which we had now fairly entered. The bitter
blast, however, gave us good speed; our bedraggled canoe rose
and fell on the waves as solemnly as a big ship. Our course was
northwestward, up the southwest side of the bay, near the shore
of what seemed to be the mainland, smooth marble islands being
on our right. About
noon we discovered the first of the
great glaciers, the one I afterward named for James Geikie, the
noted Scotch geologist. Its lofty blue cliffs, looming through
the draggled skirts of the clouds, gave a tremendous impression
of savage power, while the roar of the newborn icebergs thickened
and emphasized the general roar of the storm. An hour and a half
beyond the Geikie Glacier we ran into a slight harbor where the
shore is low, dragged the canoe beyond the reach of drifting icebergs,
and, much against my desire to push ahead, encamped, the guide
insisting that the big ice-mountain at the head of the bay
could not be reached before dark, that the landing there was dangerous
even in daylight, and that this was the only safe harbor on the
way to it. While camp was being made. I strolled along the shore
to examine the rocks and the fossil timber that abounds here.
All the rocks are freshly glaciated, even below the sea-level,
nor have the waves as yet worn off the surface polish, much less
the heavy scratches and grooves and lines of glacial contour.
The next day being Sunday, the minister wished to stay in camp;
and so, on account of the weather, did the Indians. I therefore
set out on an excursion, and spent the day alone on the mountain-slopes
above the camp, and northward, to see what I might learn. Pushing
on through rain and mud and sludgy snow, crossing many brown,
boulder-choked torrents, wading, jumping, and wallowing in
snow up to my shoulders was mountaineering of the most trying
kind. After crouching cramped and benumbed in the canoe,
poulticed in wet or damp clothing night and day, my limbs had
been asleep. This day they were awakened and in the hour of trial
proved that they had not lost the cunning learned on many a mountain
peak of the High Sierra. I reached a height of fifteen hundred
feet, on the ridge that bounds the second of the great glaciers.
All the landscape was smothered in clouds and I began to fear
that as far as wide views were concerned I had climbed in vain.
But at length the clouds lifted a little, and beneath their gray
fringes I saw the berg-filled expanse of the bay, and the
feet of the mountains that stand about it, and the imposing fronts
of five huge glaciers, the nearest being immediately beneath me.
This was my first general view of Glacier Bay, a solitude of ice
and snow and newborn rocks, dim, dreary, mysterious. I held the
ground I had so dearly won for an hour or two, sheltering myself
from the blast as best I could, while with benumbed fingers I
sketched what I could see of the landscape, and wrote a few lines
in my notebook. Then, breasting the snow again, crossing the shifting
avalanche slopes and torrents, I reached camp about dark, wet
and weary and glad.
While I was getting some coffee and hardtack, Mr. Young told me
that the Indians were discouraged, and had been talking about
turning back, fearing that I would be lost, the canoe broken,
or in some other mysterious way the expedition would come to grief
if I persisted in going farther. They had been asking him what
possible motive I could have in climbing mountains when storms
were blowing; and when he
replied that I was only seeking
knowledge, Toyatte said, "Muir must be a witch to seek knowledge
in such a place as this and in such miserable weather."
After supper, crouching about a dull fire of fossil wood, they
became still more doleful, and talked in tones that accorded well
with the wind and waters and growling torrents about us, telling
sad old stories of crushed canoes, drowned Indians, and hunters
frozen in snowstorms. Even brave old Toyatte, dreading the treeless,
forlorn appearance of the region, said that his heart was not
strong, and that he feared his canoe, on the safety of which our
lives depended, might be entering a skookum-house (jail)
of ice, from which there might be no escape; while the Hoona guide
said bluntly that if I was so fond of danger, and meant to go
close up to the noses of the ice-mountains, he would not
consent to go any farther; for we should all be lost, as many
of his tribe had been, by the sudden rising of bergs from the
bottom. They seemed to be losing heart with every howl of the
wind, and, fearing that they might fail me now that I was in the
midst of so grand a congregation of glaciers, I made haste to
reassure them, telling them that for ten years I had wandered
alone among mountains and storms, and good luck always followed
me; that with me, therefore, they need fear nothing. The storm
would soon cease and the sun would shine to show us the way we
should go, for God cares for us and guides us as long as we are
trustful and brave, therefore all childish fear must be put away.
This little speech did good. Kadachan, with some show of enthusiasm,
said he liked to travel with good-luck people; and
dignified old Toyatte declared that now his heart was strong again,
and he would venture on with me as far as I liked for my "wawa"
was "delait" (my talk was very good). The old warrior
even became a little sentimental, and said that even if the canoe
was broken he would not greatly care, because on the way to the
other world he would have good companions.
Next morning it was still raining and snowing, but the south wind
swept us bravely forward and swept the bergs from our course.
In about an hour we reached the second of the big glaciers, which
I afterwards named for Hugh Miller. We rowed up its fiord and
landed to make a slight examination of its grand frontal wall.
The berg-producing portion we found to be about a mile and
a half wide, and broken into an imposing array of jagged spires
and pyramids, and flat-topped towers and battlements, of
many shades of blue, from pale, shimmering, limpid tones in the
crevasses and hollows, to the most startling, chilling, almost
shrieking vitriol blue on the plain mural spaces from which bergs
had just been discharged. Back from the front for a few miles
the glacier rises in a series of wide steps, as if this portion
of the glacier had sunk in successive sections as it reached deep
water, and the sea had found its way beneath it. Beyond this it
extends indefinitely in a gently rising prairie like expanse,
and branches along the slopes and cañons of the Fairweather
Range.
Prom here a run of two hours brought us to the head of the bay,
and to the mouth of the northwest fiord,
at the head of
which lie the Hoona sealing-grounds, and the great glacier
now called the Pacific, and another called the Hoona. The fiord
is about five miles long, and two miles wide at the mouth. Here
our Hoona guide had a store of dry wood, which we took aboard.
Then, setting sail, we were driven wildly up the fiord, as if
the storm-wind were saying, "Go, then, if you will,
into my icy chamber; but you shall stay in until I am ready to
let you out." All this time sleety rain was falling on the
bay, and snow on the mountains; but soon after we landed the sky
began to open. The camp was made on a rocky bench near the front
of the Pacific Glacier, and the canoe was carried beyond the reach
of the bergs and berg-waves. The bergs were now crowded in a dense
pack against the discharging front, as if the storm-wind
had determined to make the glacier take back her crystal offspring
and keep them at home.
While camp affairs were being attended to, I set out to climb
a mountain for comprehensive views; and before I had reached a
height of a thousand feet the rain ceased, and the clouds began
to rise from the lower altitudes, slowly lifting their white skirts,
and lingering in majestic, wing-shaped masses about the mountains
that rise out of the broad, icy sea, the highest of all the white
mountains, and the greatest of all the glaciers I had yet seen.
Climbing higher for a still broader outlook, I made notes and
sketched, improving the precious time while sunshine streamed
through the luminous fringes of the clouds and fell on the green
waters of the fiord, the glittering bergs, the
crystal bluffs
of the vast glacier, the intensely white, far-spreading fields
of ice, and the ineffably chaste and spiritual heights of the
Fairweather Range, which were now hidden, now partly revealed,
the whole making a picture of icy wildness unspeakably pure and
sublime.
Looking southward, a broad ice-sheet was seen extending in
a gently undulating plain from the Pacific Fiord m the foreground
to the horizon, dotted and ridged here and there with mountains
which were as white as the snow-covered ice in which they
were half, or more than half, submerged. Several of the great
glaciers of the bay flow from this one grand fountain. It is an
instructive example of a general glacier covering the hills and
dales of a country that is not yet ready to be brought to the
light of day--not only covering but creating a landscape with the
features it is destined to have when, in the fullness of time,
the fashioning ice-sheet shall be lifted by the sun, and
the land become warm and fruitful. The view to the westward is
bounded and almost filled by the glorious Fairweather Mountains,
the highest among them springing aloft in sublime beauty to a
height of nearly sixteen thousand feet, while from base to summit
every peak and spire and dividing ridge of all the mighty host
was spotless white, as if painted. It would seem that snow could
never be made to lie on the steepest slopes and precipices unless
plastered on when wet, and then frozen. But this snow could not
have been wet. It must have been fixed by being driven and set
in small particles like the storm-dust of
drifts, which,
when in this condition, is fixed not only on sheer cliffs, but
in massive, overcurling cornices. Along the base of this majestic
range sweeps the Pacific Glacier, fed by innumerable cascading
tributaries, and discharging into the head of its fiord by two
mouths only partly separated by the brow of an island rock about
one thousand feet high, each nearly a mile wide.
Dancing down the mountain to camp, my mind glowing like the sunbeaten
glaciers, I found the Indians seated around a good fire, entirely
happy now that the farthest point of the journey was safely reached
and the long, dark storm was cleared away. How hopefully, peacefully
bright that night were the stars in the frosty sky, and how impressive
was the thunder of the icebergs, rolling, swelling, reverberating
through the solemn stillness! I was too happy to sleep.
About daylight next morning we crossed the fiord and landed on
the south side of the rock that divides the wall of the great
glacier. The whiskered faces of seals dotted the open spaces between
the bergs, and I could not prevent John and Charley and Kadachan
from shooting at them. Fortunately, few, if any, were hurt. Leaving
the Indians in charge of the canoe, I managed to climb to the
top of the wall by a good deal of step-cutting between the
ice and dividing rock, and gained a good general view of the glacier.
At one favorable place I descended about fifty feet below the
side of the glacier, where its denuding, fashioning action was
clearly shown. Pushing back
from here, I found the surface
crevassed and sunken in steps, like the Hugh Miller Glacier, as
if it were being undermined by the action of tide-waters.
For a distance of fifteen or twenty miles the river-like
ice-flood is nearly level, and when it recedes, the ocean water
will follow it, and thus form a long extension of the fiord, with
features essentially the same as those now extending into the
continent farther south, where many great glaciers once poured
into the sea, though scarce a vestige of them now exists. Thus
the domain of the sea has been, and is being, extended in these
ice-sculptured lands, and the scenery of their shores enriched.
The brow of the dividing rock is about a thousand feet high, and
is hard beset by the glacier. A short time ago it was at least
two thousand feet below the surface of the over-sweeping
ice; and under present climatic conditions it will soon take its
place as a glacier-polished island in the middle of the fiord,
like a thousand others in the magnificent archipelago. Emerging
from its icy sepulchre, it gives a most telling illustration of
the birth of a marked feature of a landscape. In this instance
it is not the mountain, but the glacier, that is in labor, and
the mountain itself is being brought forth.
The Hoona Glacier enters the fiord on the south side, a short
distance below the Pacific, displaying a broad and far-reaching
expanse, over which many lofty peaks are seen; but the front wall,
thrust into the fiord, is not nearly so interesting as that of
the Pacific, and I did not observe any bergs discharged from it.
In the evening, after witnessing the unveiling of the majestic
peaks and glaciers and their baptism in the down-pouring
sunbeams, it seemed inconceivable that nature could have anything
finer to show us. Nevertheless, compared with what was to come
the next morning, all that was as nothing. The calm dawn gave
no promise of anything uncommon. Its most impressive features
were the frosty clearness of the sky and a deep, brooding stillness
made all the more striking by the thunder of the newborn bergs.
The sunrise we did not see at all, for we were beneath the shadows
of the fiord cliffs; but in the midst of our studies, while the
Indians were getting ready to sail, we were startled by the sudden
appearance of a red light burning with a strange unearthly splendor
on the topmost peak of the Fairweather Mountains. Instead of vanishing
as suddenly as it had appeared, it spread and spread until the
whole range down to the level of the glaciers was filled with
the celestial fire. In color it was at first a vivid crimson,
with a thick, furred appearance, as fine as the alpenglow, yet
indescribably rich and deep--not in the least like a garment or
mere external flush or bloom through which one might expect to
see the rocks or snow, but every mountain apparently was glowing
from the heart like molten metal fresh from a furnace. Beneath
the frosty shadows of the fiord we stood hushed and awe-stricken,
gazing at the holy vision; and had we seen the heavens opened
and God made manifest, our attention could not have been more
tremendously strained. When the highest peak began to burn, it
did
not seem to be steeped in sunshine, however glorious,
but rather as if it had been thrust into the body of the sun itself.
Then the supernal fire slowly descended, with a sharp line of
demarcation separating it from the cold, shaded region beneath;
peak after peak, with their spires and ridges and cascading glaciers,
caught the heavenly glow, until all the mighty host stood transfigured,
hushed, and thoughtful, as if awaiting the coming of the Lord.
The white, rayless light of morning, seen when I was alone amid
the peaks of the California Sierra, had always seemed to me the
most telling of all the terrestrial manifestations of God. But
here the mountains themselves were made divine, and declared His
glory in terms still more impressive. How long we gazed I never
knew. The glorious vision passed away in a gradual, fading change
through a thousand tones of color to pale yellow and white, and
then the work of the ice-world went on again in everyday
beauty. The green waters of the fiord were filled with sun-spangles;
the fleet of icebergs set forth on their voyages with the upspringing
breeze; and on the innumerable mirrors and prisms of these bergs,
and on those of the shattered crystal walls of the glaciers, common
white light and rainbow light began to burn, while the mountains
shone in their frosty jewelry, and loomed again in the thin azure
in serene terrestrial majesty. We turned and sailed away, joining
the outgoing bergs, while "Gloria in excelsis" still
seemed to be sounding over all the white landscape, and our burning
hearts were ready for any fate, feeling that, whatever the future
might
have in store, the treasures we had gained this glorious
morning would enrich our lives forever.
When we arrived at the mouth of the fiord, and rounded the massive
granite headland that stands guard at the entrance on the north
side, another large glacier, now named the Reid, was discovered
at the head of one of the northern branches of the bay. Pushing
ahead into this new fiord, we found that it was not only packed
with bergs, but that the spaces between the bergs were crusted
with new ice, compelling us to turn back while we were yet several
miles from the discharging frontal wall. But though we were not
then allowed to set foot on this magnificent glacier, we obtained
a fine view of it, and I made the Indians cease rowing while I
sketched its principal features. Thence, after steering northeastward
a few miles, we discovered still another large glacier, now named
the Carroll. But the fiord into which this glacier flows was,
like the last, utterly inaccessible on account of ice, and we
had to be content with a general view and sketch of it, gained
as we rowed slowly past at a distance of three or four miles.
The mountains back of it and on each side of its inlet are sculptured
in a singularly rich and striking style of architecture, in which
subordinate peaks and gables appear in wonderful profusion, and
an imposing conical mountain with a wide, smooth base stands out
in the main current of the glacier, a mile or two back from the
discharging ice-wall.
We now turned southward down the eastern shore of the bay, and
in an hour or two discovered a glacier
of the second class,
at the head of a comparatively short fiord that winter had not
yet closed. Here we landed, and climbed across a mile or so of
rough boulder-beds, and back upon the wildly broken, receding
front of the glacier, which, though it descends to the level of
the sea, no longer sends off bergs. Many large masses, detached
from the wasting front by irregular melting, were partly buried
beneath mud, sand, gravel, and boulders of the terminal moraine.
Thus protected, these fossil icebergs remain unmelted for many
years, some of them for a century or more, as shown by the age
of trees growing above them, though there are no trees here as
yet. At length melting, a pit with sloping sides is formed by
the falling in of the overlying moraine material into the space
at first occupied by the buried ice. In this way are formed the
curious depressions in drift-covered regions called kettles
or sinks. On these decaying glaciers we may also find many interesting
lessons on the formation of boulders and boulder-beds, which
in all glaciated countries exert a marked influence on scenery,
health, and fruitfulness.
Three or four miles farther down the bay, we came to another fiord,
up which we sailed in quest of more glaciers, discovering one
in each of the two branches into which the fiord divides. Neither
of these glaciers quite reaches tide-water. Notwithstanding
the apparent fruitfulness of their fountains, they are in the
first stage of decadence, the waste from melting and evaporation
being greater now than the supply of new ice from their snowy
fountains. We reached the one in
the north branch, climbed
over its wrinkled brow, and gained a good view of the trunk and
some of the tributaries, and also of the sublime gray cliffs of
its channel.
Then we sailed up the south branch of the inlet, but failed to
reach the glacier there, on account of a thin sheet of new ice.
With the tent-poles we broke a lane for the canoe for a little
distance; but it was slow work, and we soon saw that we could
not reach the glacier before dark. Nevertheless, we gained a fair
view of it as it came sweeping down through its gigantic gateway
of massive Yosemite rocks three or four thousand feet high. Here
we lingered until sundown, gazing and sketching; then turned back,
and encamped on a bed of cobblestones between the forks of the
fiord.
We gathered a lot of fossil wood and after supper made a big fire,
and as we sat around it the brightness of the sky brought on a
long talk with the Indians about the stars; and their eager, childlike
attention was refreshing to see as compared with the deathlike
apathy of weary town-dwellers, in whom natural curiosity
has been quenched in toil and care and poor shallow comfort.
After sleeping a few hours, I stole quietly out of the camp, and
climbed the mountain that stands between the two glaciers. The
ground was frozen, making the climbing difficult in the steepest
places; but the views over the icy bay, sparkling beneath the
stars, were enchanting. It seemed then a sad thing that any part
of so precious a night had been lost in sleep. The starlight
was so full that I distinctly saw not only the berg-filled
bay, but most of the lower portions of the glaciers, lying pale
and spirit-like amid the mountains. The nearest glacier in
particular was so distinct that it seemed to be glowing with light
that came from within itself. Not even in dark nights have I ever
found any difficulty in seeing large glaciers; but on this mountain-top,
amid so much ice, in the heart of so clear and frosty a night,
everything was more or less luminous, and I seemed to be poised
in a vast hollow between two skies of almost equal brightness.
This exhilarating scramble made me glad and strong and I rejoiced
that my studies called me before the glorious night succeeding
so glorious a morning had been spent!
I got back to camp in time for an early breakfast, and by daylight
we had everything packed and were again under way. The fiord was
frozen nearly to its mouth, and though the ice was so thin it
gave us but little trouble in breaking a way for the canoe, yet
it showed us that the season for exploration in these waters was
well-nigh over. We were in danger of being imprisoned in
a jam of icebergs, for the water-spaces between them freeze
rapidly, binding the floes into one mass. Across such floes it
would be almost impossible to drag a canoe, however industriously
we might ply the axe, as our Hoona guide took great pains to warn
us. I would have kept straight down the bay from here, but the
guide had to be taken home, and the provisions we left at the
bark hut had to be got on board. We therefore crossed over to
our
Sunday storm-camp, cautiously boring a way through
the bergs. We found the shore lavishly adorned with a fresh arrival
of assorted bergs that had been left stranded at high tide. They
were arranged in a curving row, looking intensely clear and pure
on the gray sand, and, with the sunbeams pouring through them,
suggested the jewel-paved streets of the New Jerusalem.
On our way down the coast, after examining the front of the beautiful
Geikie Glacier, we obtained our first broad view of the great
glacier afterwards named the Muir, the last of all the grand company
to be seen, the stormy weather having hidden it when we first
entered the bay. It was now perfectly clear, and the spacious,
prairie-like glacier, with its many tributaries extending
far back into the snowy recesses of its fountains, made a magnificent
display of its wealth, and I was strongly tempted to go and explore
it at all hazards. But winter had come, and the freezing of its
fiords was an insurmountable obstacle. I had, therefore, to be
content for the present with sketching and studying its main features
at a distance.

When we arrived at the Hoona hunting-camp, men, women, and
children came swarming out to welcome us. In the neighborhood
of this camp I carefully noted the lines of demarkation between
the forested and deforested regions. Several mountains here are
only in part deforested, and the lines separating the bare and
the forested portions are well defined. The soil, as well as the
trees, had slid off the steep slopes, leaving the edge of the
woods raw-looking and rugged.
At the mouth of the bay a series of moraine islands show that
the trunk glacier that occupied the bay halted here for some time
and deposited this island material as a terminal moraine; that
more of the bay was not filled in shows that, after lingering
here, it receded comparatively fast. All the level portions of
trunks of glaciers occupying ocean fiords, instead of melting
back gradually in times of general shrinking and recession, as
inland glaciers with sloping channels do, melt almost uniformly
over all the surface until they become thin enough to float. Then,
of course, with each rise and fall of the tide, the sea water,
with a temperature usually considerably above the freezing-point,
rushes in and out beneath them, causing rapid waste of the nether
surface, while the upper is being wasted by the weather, until
at length the fiord portions of these great glaciers become comparatively
thin and weak and are broken up and vanish almost simultaneously.
Glacier Bay is undoubtedly young as yet. Vancouver's chart, made
only a century ago, shows no trace of it, though found admirably
faithful in general. It seems probable, therefore, that even then
the entire bay was occupied by a glacier of which all those described
above, great though they are, were only tributaries. Nearly as
great a change has taken place in Sum Dum Bay since Vancouver's
visit, the main trunk glacier there having receded from eighteen
to twenty five miles from the line marked on his chart. Charley,
who was here when a boy, said that the place had so changed that
he hardly recognized it, so
many new islands had been born
in the mean time and so much ice had vanished. As we have seen,
this Icy Bay is being still farther extended by the recession
of the glaciers. That this whole system of fiords and channels
was added to the domain of the sea by glacial action is to my
mind certain.
We reached the island from which we had obtained our store of
fuel about half-past six and camped here for the night, having
spent only five days in Sitadaka, sailing round it, visiting and
sketching all the six glaciers excepting the largest, though I
landed only on three of them,--the Geikie, Hugh Miller, and Grand
Pacific,--the freezing of the fiords in front of the others rendering
them inaccessible at this late season.
