J. Bond/P. Lipovsky - Surficial Geology of Stevenson Ridge/NE Kluane Map Areas
Surficial geology and Quaternary history of Stevenson Ridge (115J) and NE Kluane Lake (115G) map areas, Yukon
Forty years of GSC and YTG surficial mapping in southern Yukon has amounted to nearly complete mapping coverage. One large area remains unmapped in west-central Yukon in the Stevenson Ridge (115J) and northeast Kluane Lake (115G) map areas. This area is particularly interesting because it straddles the all-time limit of Pleistocene glaciation originating from the St. Elias Mountains. Multiple glacial limits are preserved and glacial deposits from early to middle Pleistocene local ice cap complexes are present. This area has excellent potential for the preservation of complex Quaternary stratigraphy. The combination of favourable bedrock geology and large areas of unglaciated terrain also make this region highly prospective for new placer discoveries.
A four-year project is anticipated in this area. The focus of this field season will largely be reconnaissance surficial mapping with air photo interpretation beginning in the winter of 2007-08. Glacial limit mapping, geomorphological studies and Quaternary stratigraphy will be the focus of the reconnaissance work. The Yukon Geological Survey is looking for additional support for the surficial mapping in the form of graduate theses. For more information please contact Jeff Bond or Panya Lipovsky. At the same time, a large bedrock-mapping project is being undertaken in the same area by Don Murphy and others.
