Abstract
A general correlation can be made of certain major late Pleistocene stratigraphic units in Western Canada. The precise age limits and the degree of synchrony of these are not known, however, it appears that Early, Middle and Late subdivisions of Wisconsin time that are used in eastern North America can be equally usefully applied in the west. In the southern Cordillera the last Interglacial/ Sangamon/ appears to have been followed by a cool period and then by an ice advance that covered the entire area. These events are nonglacial conditions that prevailed from beyond the limit of radiocarbon dating until the build up of the last ice advance /20 - 25, 000 B.P./. The climate of this nonglacial at times approached that of present but at other times, particularly during late stages of the period, was cooler. Late Wisconsin ice covered the entire region. In southwest Yukon a similar 3 part glacial- nonglacial- glacial period in the Interior Plains appear to correlate well with the Cordilleran record. The complexity of the deposits lying between the mid-Wisconsin break and the top of the Sangamon however suggests that the area may have been subjected to Early Wisconsin glacial fluctuations not recognized in the Cordillera.
