Abstract
This report assembles and correlates evidence of successive advances of Cordilleran ice sheets in the Yukon interior, and of valley glaciers in adjacent mountains. Limits of a late Wisconsin advance are marked by moraines and other ice-marginal features; features of a more extensive, early Wisconsin advance are relatively subdued but distinguishable over much of the area. One or more older and more extensive advances are evident from glacial deposits lacking distinctive geomorphic form. Flow patterns indicate that during the late (McConnell) advance, the ice sheet moved as two more or less distinct lobes--a N and NW flowing Cassiar lobe, and a NW and W flowing Selwyn lobe. Valley glaciers emanating from St. Elias, and from Wernecke and eastern Ogilvie Mts. merged with the two lobes, respectively, whereas valley glaciers of western Ogilvie Mts. remained independent.
