... more than 60 000 years ago. Little information is available on the climate of this period, but permafrost may have been present at one time during final stages of deposition of Westwold Sediments. The latter part of this nonglacial period is probably correlative with the early Wisconsin Substage...

... is probably pre-Altamont in age and was subjected to vigorous frost action during the Altamont substage. The climate ameliorated perhaps with the advent of the post-glacial optimum and possibly coincident with the development of prairies. A recent change from prairie to forest perhaps indicates a slight...

... investigated in detail. Glacial drift of the several substages of the Wisconsin is locally mantled with as much as 30 feet of loess. The Tazewell-Cary interval is represented in this loess by a buried, immature soil profile. 1 This paper is a condensation of part of a dissertation presented...

During the latest Wisconsin stage, perhaps in association with the drainage of Glacial Lake Agassiz, floodwaters overflowed...

... of the drift which is bordered by the terminal moraine, long recognized as of Wisconsin age, is a thin, patchy drift almost devoid of glacial topography. Although this drift was long called “old” or “pre-Wisconsin” it is now thought that most, if not all, the extra-morainic deposits are Iowan, although some...

.... The characteristic Sangamon soil was not developed on uneroded remnants of the soil of Yarmouth age because of a wet, poorly drained environment. A large collection of molluscs obtained from this gley soil supports stratigraphic evidence indicating a Yarmouth age. Alluviation during the glacial substages...

...EDWARD B. EVENSON Abstract Recent investigations in the Ontario, Huron, and Erie basins and in the Glacial Grand River demonstrate that the entire Glenwood Stage (640 ft above tide [a.t.]), and at least an early portion of the Calumet Stage (620 ft a.t.), of Glacial Lake Chicago are pre-Twocreekan...
