...region around Lake Champlain, New York, rich in Paleozoic rocks, crystalline rocks, glacial, and post-glacial formations, will furnish an abundance of material for students who have completed courses in Geology 4 and 5 or their equivalent. The party, under the tutelage of A. C. Swinnerton, professor at Antioch College, will be formed at Ticonderoga, New York, July 7. From there, the group will continue to the borders of Lake Champlain, near which a five weeks' study of field methods and geologic structure will ensue. Members of the party will have tents and cots furnished for their...
...systematic botanist, this region, which has never been glaciated or was glaciated only during an early glacial advance, is dramatically interesting; for, as we are now learning to expect, in such regions there are hundreds of plants now living which are so conservative that they have never migrated into the adjacent regions recently covered by Wisconsin...
...species which constitute this relic-flora must have lived right through the last glacial period where they are; and a study of the other regions of the Northern Hemisphere which were not invaded by the last ice-sheets has shown an exactly parallel situation. In these spots, then, we have relies of an ancient flora which in regions of very recent glaciation has been completely exterminated. From a purely evolutionary point of view, these old plants are particularly interesting because they are species with very sharply defined characteristics and are now so fixed in their fundamental characters that they show...
...Approach Glacial Conditions...
Although the highest tablelands and slopes of western Newfoundland have had no recent glacial cap, some of them are today not very far removed from a local glacial condition. Practically every summer, compact snowbanks lie on the northern-facing slopes; and it is evident that, by a very slight reduction of the mean annual temperature these snowfields would be transformed into alpine glaciers...
