Travels in Alaska

by John Muir

Following a dry channel for about a mile, I came suddenly upon the main outlet of the glacier, which in the imperfect light seemed as large as the river, about one hundred and fifty feet wide, and perhaps three or four feet deep. A little farther up it was only about fifty feet wide and rushing on with impetuous roaring force in its rocky channel, sweeping forward sand, gravel, cobblestones, and boulders, the bump and rumble sounds of the largest of these rolling stones being readily heard in the midst of the roaring. It was too swift and rough to ford, and no bridge tree could be found, for the great floods had cleared everything out of their way. I was therefore compelled to keep on up the right bank, however difficult the way. Where a strip of bare boulders lined the margin, the walking was easy, but where the current swept close along the ragged edge of the forest, progress was difficult and slow on account of snow-crinkled and interlaced thickets of alder and willow, reinforced with fallen trees and thorny devil’s-club (Echinopanax horridum), making a jungle all but impenetrable. The mile of this extravagantly difficult growth through which I struggled, inch by inch, will not soon be forgotten. At length arriving within a few hundred yards of the glacier, full of panax barbs, I found that both the glacier and its unfordable stream were pressing hard against a shelving cliff, dangerously steep, leaving no margin, and compelling me to scramble along its face before I could get on to the glacier. But by sunrise all these cliff, jungle, and torrent troubles were overcome and I gladly found myself free on the magnificent ice-river.

The curving, out-bulging front of the glacier is about two miles wide, two hundred feet high, and its surface for a mile or so above the front is strewn with moraine detritus, giving it a strangely dirty, dusky look, hence its name, the “Dirt Glacier,” this detritus-laden portion being all that is seen in passing up the river. A mile or two beyond the moraine-covered part I was surprised to find alpine plants growing on the ice, fresh and green, some of them in full flower. These curious glacier gardens, the first I had seen, were evidently planted by snow avalanches from the high walls. They were well watered, of course, by the melting surface of the ice and fairly well nourished by humus still attached to the roots, and in some places formed beds of considerable thickness. Seedling trees and bushes also were growing among the flowers. Admiring these novel floating gardens, I struck out for the middle of the pure white glacier, where the ice seemed smoother, and then held straight on for about eight miles, where I reluctantly turned back to meet the steamer, greatly regretting that I had not brought a week’s supply of hardtack to allow me to explore the glacier to its head, and then trust to some passing canoe to take me down to Buck Station, from which I could explore the Big Stickeen Glacier.

Altogether, I saw about fifteen or sixteen miles of the main trunk. The grade is almost regular, and the walls on either hand are about from two to three thousand feet high, sculptured like those of Yosemite Valley. I found no difficulty of an extraordinary kind. Many a crevasse had to be crossed, but most of them were narrow and easily jumped, while the few wide ones that lay in my way were crossed on sliver bridges or avoided by passing around them. The structure of the glacier was strikingly revealed on its melting surface. It is made up of thin vertical or inclined sheets or slabs set on edge and welded together. They represent, I think, the successive snowfalls from heavy storms on the tributaries. One of the tributaries on the right side, about three miles above the front, has been entirely melted off from the trunk and has receded two or three miles, forming an independent glacier. Across the mouth of this abandoned part of its channel the main glacier flows, forming a dam which gives rise to a lake. On the head of the detached tributary there are some five or six small residual glaciers, the drainage of which, with that of the snowy mountain slopes above them, discharges into the lake, whose outlet is through a channel or channels beneath the damming glacier. Now these sub-channels are occasionally blocked and the water rises until it flows alongside of the glacier, but as the dam is a moving one, a grand outburst is sometimes made, which, draining the large lake, produces a flood of amazing power, sweeping down immense quantities of moraine material and raising the river all the way down to its mouth, so that several trips may occasionally be made by the steamers after the season of low water has laid them up for the year. The occurrence of these floods are, of course, well known to the Indians and steamboat men, though they know nothing of their cause. They simply remark, “The Dirt Glacier has broken out again.”

I greatly enjoyed my walk up this majestic ice-river, charmed by the pale-blue, ineffably fine light in the crevasses, moulins, and wells, and the innumerable azure pools in basins of azure ice, and the network of surface streams, large and small, gliding, swirling with wonderful grace of motion in their frictionless channels, calling forth devout admiration at almost every step and filling the mind with a sense of Nature’s endless beauty and power. Looking ahead from the middle of the glacier, you see the broad white flood, though apparently rigid as iron, sweeping in graceful curves between its high mountain-like walls, small glaciers hanging in the hollows on either side, and snow in every form above them, and the great down-plunging granite buttresses and headlands of the walls marvelous in bold massive sculpture; forests in side cañons to within fifty feet of the glacier; avalanche pathways overgrown with alder and willow; innumerable cascades keeping up a solemn harmony of water sounds blending with those of the glacier moulins and rills; and as far as the eye can reach, tributary glaciers at short intervals silently descending from their high, white fountains to swell the grand central ice-river.

In the angle formed by the main glacier and the lake that gives rise to the river floods, there is a massive granite dome sparsely feathered with trees, and just beyond this yosemitic rock is a mountain, perhaps ten thousand feet high, laden with ice and snow which seemed pure pearly white in the morning light. Last evening as seen from camp it was adorned with a cloud streamer, and both the streamer and the peak were flushed in the alpenglow. A mile or two above this mountain, on the opposite side of the glacier, there is a rock like the Yosemite Sentinel; and in general all the wall rocks as far as I saw them are more or less yosemitic in form and color and streaked with cascades.

But wonderful as this noble ice-river is in size and depth and in power displayed, far more wonderful was the vastly greater glacier three or four thousand feet, or perhaps a mile, in depth, whose size and general history is inscribed on the sides of the walls and over the tops of the rocks in characters which have not yet been greatly dimmed by the weather. Comparing its present size with that when it was in its prime, is like comparing a small rivulet to the same stream when it is a roaring torrent.

The return trip to the camp past the shelving cliff and through the weary devil’s-club jungle was made in a few hours. The Indians had gone off picking berries, but were on the watch for me and hailed me as I approached. The captain had called for me, and, after waiting three hours, departed for Wrangell without leaving any food, to make sure, I suppose, of a quick return of his Indians and canoe. This was no serious matter, however, for the swift current swept us down to Buck Station, some thirty-five miles distant, by eight o’clock. Here I remained to study the “Big Stickeen Glacier,” but the Indians set out for Wrangell soon after supper, though I invited them to stay till morning.

The weather that morning, August 27, was dark and rainy, and I tried to persuade myself that I ought to rest a day before setting out on new ice work. But just across the river the “Big Glacier” was staring me in the face, pouring its majestic flood through a broad mountain gateway and expanding in the spacious river valley to a width of four or five miles, while dim in the gray distance loomed its high mountain fountains. So grand an invitation displayed in characters so telling was of course irresistible, and body-care and weather-care vanished.

Mr. Choquette, the keeper of the station, ferried me across the river, and I spent the day in getting general views and planning the work that had been long in mind. I first traced the broad, complicated terminal moraine to its southern extremity, climbed up the west side along the lateral moraine three or four miles, making my way now on the glacier, now on the moraine-covered bank, and now compelled to climb up through the timber and brush in order to pass some rocky headland, until I reached a point commanding a good general view of the lower end of the glacier. Heavy, blotting rain then began to fall, and I retraced my steps, oftentimes stopping to admire the blue ice-caves into which glad, rejoicing streams from the mountain-side were hurrying as if going home, while the glacier seemed to open wide its crystal gateways to welcome them.

The following morning blotting rain was still falling, but time and work was too precious to mind it. Kind Mr. Choquette put me across the river in a canoe, with a lot of biscuits his Indian wife had baked for me and some dried salmon, a little sugar and tea, a blanket, and a piece of light sheeting for shelter from rain during the night, all rolled into one bundle.
