| Abstract/Notes | Ages of glacial deposits in cirques of the Shuswap Highland, British Columbia are approximated or bracketed using tephrochronology, radiocarbon dating and lichenometry. There is evidence for two minor Holocene glacial advances. The younger, named the Raft Mountain Advance, is defined by the type Raft Mountain moraine, which is about 100 years old judging from Rhizocarpon lichens. No volcanic ash is found on the moraine or its equivalents. The older, named the Dunn Peak Advance, is defined by the type Dunn Peak moraine and equivalent deposits in the Dunn Peak area. These deposits bear Mazama ash and are thus older than 6600 years; one of the moraines has a minimum radiocarbon age of about 7400 years. The deposits are younger than the Late Wisconsin deglaciation in southern B.C. (about 11 000 years BP). In addition, an earlier event, possibly a stillstand, is represented by a moraine (the Harper Creek moraine) downstream of the type Dunn Peak moraine. This moraine is also bracketed between 6600 and 11 000 years in age. The Dunn Peak Advance may be correlative with an Early Holocene Advance reported from the Canadian Rockies and northern American Rockies, and the Raft Mountain Advance is correlative with very recent advances reported from several parts of the world. |
