"Massive ice and ice-rich sediments from a number of sites in central and northern Yukon have been examined stratigraphically and isotopically. Within the central Yukon, ice-wedge ice, segregated ice and frost-blister ice have been identified. Along the northern Yukon coastal plain, massive ice and ice-rich sediments, exposed in the headwalls of progressive thaw slides, have been interpreted as ice-wedge ice, segregated ice and buried glacier ice. The buried glacier ice, probably of early Wisconsinan age, exists near King Point, Kay Point, and on Herschel Island in what have been described as ice-thrust moraines. Each ice type displays a characteristic isotopic signature which is useful in identifying the origin of the ice"--Abstract, p. 2.
