It will be half a century before it too produces seeds. arises a little cone with a crater on top that is 700 feet above the lake level. This volcanic activity is, geologically speaking, both ancient and modern, for a lot of it is imposed upon an old land surface that was obviously carved by mountain glaciers during the Pleistocene ice advances. The Cascades continue north to the region of Kamloops on the North Thompson River in British Columbia. They are clothed, as we have said, in a predominantly coniferous forest— allied to that of the Northwest Pacific Coastal Fringe—composed of Sitka spruce, firs, and an intermingling of willows and aspen. The whole northern part of the range has been recently and mightily glaciated, so that most of its valleys are shaped like flattened-out Us. The upper slopes are mantled in short alpine vegetation, often with scattered trees, and the tops of the moun- tains are either bald or snow-covered. All the great volcanic peaks wear a cap of snow and ice. The fauna of the Cascades is quite different from that of the Rockies, many of the larger animals, for example the Moose, being absent. Most of the animal life was pushed out by the over-all glaciation. and repopulation came from the south as the ice retreated Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Sanderson, Ivan Terence, 1911-1973.
