...small precipitation in recent winters, but the extinct glciation more than compensated. On both sides of the Whitney group, glaciers formed in the cirques under the peaks and flowed down east and west, but in greater volume westward, facing the Pacific. Every stream has a chain of glacial lakes at the head, and between them, as the ice and its rock burden moved down, it carved and gouged and polished the granite in typical glacial forms; a couple of miles below. Whitney on Crabtree Creek a casual estimate of the thickness of the ice gave 500 feet...
...Near the front of the Muir glacier, only recently uncovered, are the remains of a pre-glacial forest which was destroyed and covered up by the advancing ice several hundred years...
...Another object of the expedition than the recording of glacial changes, was the studying of possible routes of ascent of the peaks of the Fairweather Range, situated near Glacier Bay. These mountains present a large field for mountaineering, one that will not be exhausted for years to come. The higher peaks culminating in Mr. Fairweather, 15,400 feet in height are without exception very difficult of ascent...
...partly was also fortunate in sighting a glacier bear, a rare variation of the black bear, found only in the glacial regions of Alaska. Its coat is light gray, similar to that of an ordinary gray squirrel. Comparatively few of these animals have ever been seen or studied, as they are extremely scarce...
...Johnstown mastodon is presumably a member of the species which roamed widely over the central states while the ice sheets were retreating northward during the last glacial epoch, an epoch of geological history which reached its climax between 25,000 and 50,000 years ago. This particular mastodon wandered around in Licking country after the ice had melted far to the northward from this place, as indicated by the fact that the remains are in swamp muck on top of glacial drift. It therefore lived between 5,000 and 30,000 years...
