Glacial history and stratigraphy of the North Fork of the Big Lost River, Pioneer Mountains, Idaho.

Deposits of two extensive glaciations, and one period of restricted glacier advance (or periglacial activity), have been mapped and tentatively correlated within the area. The two periods of glacial activity were designated 'Kane advance' (older) and 'North Fork advance' (younger). A still younger phase, largely a period of periglacial activity, was described and designated 'Neoglacial'. The terminal moraines of the Kane and North Fork advances can be differentiated accurately by using morphologic and pedologic (qualitative) relative age parameters. -from Authors
