...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...
...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...

The latter ultimately robbed the former and a vast river, called Warren River after the engineer who traced its old scourway, carried the entire system's outlet. The Chicago canal follows that scourway, deepened but a few feet. There was, in the Warren River's day, a "Lake Chicago" spreading out over the present state of Michigan ; Huron, Erie and Ontario were a "Lake...
