A Few Small Ones Are Rattling Down The Steep Slope.

I must go to bed.

July 15. I climbed the dome to plan a way, scan the glacier, and take bearings, etc., in case of storms. The main divide is about fifteen hundred feet; the second divide, about fifteen hundred also, is about one and one half miles southeastward. The flow of water on the glacier noticeably diminished last night though there was no frost. It is now already increasing. Stones begin to roll into the crevasses and into new positions, sliding against each other, half turning over or falling on moraine ridges. Mud pellets with small pebbles slip and roll slowly from ice-hummocks again and again. How often and by how many ways are boulders finished and finally brought to anything like permanent form and place in beds for farms and fields, forests and gardens. Into crevasses and out again, into moraines, shifted and reinforced and reformed by avalanches, melting from pedestals, etc. Rain, frost, and dew help in the work; they are swept in rills, caught and ground in pot-hole mills. Moraines of washed pebbles, like those on glacier margins, are formed by snow avalanches deposited in crevasses, then weathered out and projected on the ice as shallow raised moraines. There is one such at this camp.

A ptarmigan is on a rock twenty yards distant, as if on show. It has red over the eye, a white line, not conspicuous, over the red, belly white, white markings over the upper parts on ground of brown and black wings, mostly white as seen when flying, but the coverts the same as the rest of the body. Only about three inches of the folded primaries show white. The breast seems to have golden iridescent colors, white under the wings. It allowed me to approach within twenty feet. It walked down a sixty degree slope of the rock, took flight with a few whirring wing-beats, then sailed with wings perfectly motionless four hundred yards down a gentle grade, and vanished over the brow of a cliff. Ten days ago Loomis told me that he found a nest with nine eggs. On the way down to my sled I saw four more ptarmigans. They utter harsh notes when alarmed. "Crack, chuck, crack," with the r rolled and prolonged. I also saw fresh and old goat-tracks and some bones that suggest wolves.

There is a pass through the mountains at the head of the third glacier. Fine mountains stand at the head on each side. The one on the northeast side is the higher and finer every way. It has three glaciers, tributary to the third. The third glacier has altogether ten tributaries, five on each side. The mountain on the left side of White Glacier is about six thousand feet high. The moraines of Girdled Glacier seem scarce to run anywhere. Only a little material is carried to Berg Lake. Most of it seems to be at rest as a terminal on the main glacier-field, which here has little motion. The curves of these last as seen from this mountain-top are very beautiful.

It has been a glorious day, all pure sunshine. An hour or more before sunset the distant mountains, a vast host, seemed more softly ethereal than ever, pale blue, ineffably fine, all angles and harshness melted off in the soft evening light. Even the snow and the grinding, cascading glaciers became divinely tender and fine in this celestial amethystine light. I got back to camp at 7.15, not tired. After my hardtack supper I could have climbed the mountain again and got back before sunrise, but dragging the sled tires me. I have been out on the glacier examining a moraine-like mass about a third of a mile from camp. It is perhaps a mile long, a hundred yards wide, and is thickly strewn with wood. I think that it has been brought down the mountain by a heavy snow avalanche, loaded on the ice, then carried away from the shore in the direction of the flow of the glacier. This explains detached moraine-masses. This one seems to have been derived from a big roomy cirque or amphitheatre on the northwest side of this Snow Dome Mountain.

To shorten the return journey I was tempted to glissade down what appeared to be a snow-filled ravine, which was very steep. All went well until I reached a bluish spot which proved to be ice, on which I lost control of myself and rolled into a gravel talus at the foot without a scratch. Just as I got up and was getting myself orientated, I heard a loud fierce scream, uttered in an exulting, diabolical tone of voice which startled me, as if an enemy, having seen me fall, was glorying in my death. Then suddenly two ravens came swooping from the sky and alighted on the jag of a rock within a few feet of me, evidently hoping that I had been maimed and that they were going to have a feast. But as they stared at me, studying my condition, impatiently waiting for bone-picking time, I saw what they were up to and shouted, "Not yet, not yet!"

July 16. At 7 A.M. I left camp to cross the main glacier. Six ravens came to the camp as soon as I left. What wonderful eyes they must have! Nothing that moves in all this icy wilderness escapes the eyes of these brave birds. This is one of the loveliest mornings I ever saw in Alaska; not a cloud or faintest hint of one in all the wide sky. There is a yellowish haze in the east, white in the west, mild and mellow as a Wisconsin Indian Summer, but finer, more ethereal, God's holy light making all divine.

In an hour or so I came to the confluence of the first of the seven grand tributaries of the main Muir Glacier and had a glorious view of it as it comes sweeping down in wild cascades from its magnificent, pure white, mountain-girt basin to join the main crystal sea, its many fountain peaks, clustered and crowded, all pouring forth their tribute to swell its grand current.
