AbstractAt the onset of the Late Wisconsinan Fraser Glaciation, ice advanced from the Cariboo Mountains to the west and southwest within the Bonaparte Lake map area of south central British Columbia. As glaciation intensified, ice from the Coast and Cariboo mountains coalesced over the Interior Plateau resulting in the development of an ice divide north of the map area from which ice flowed to the south. These two general phases of ice flow influenced glacial transport over this region as illustrated by the distribution of terbium in till west and south of the Raft Batholith. Consequently, tracing the source of high gold content of till near the northern edge of the Thuya Batholith will need to take into account these two vectors of glacial transport.
