Welcome to the Yukon Geological Survey's Integrated Data System (YGSIDS). We are in the process of merging all of our data into one system (see the current state of the conversion process). When this process is complete, the YGSIDS will include all of the Yukon Geological Survey's publicly accessible data.

Abstract

Preliminary investigation of surficial geology in northern Kluane Range has resulted in new interpretations of Pleistocene ice cover including extensive unglaciated terrain and restricted glaciation during the Last Glacial Maximum. Two glacial limits are identified: a higher limit recording the most extensive glaciation of the area; and a lower limit that records younger, less extensive glaciation. This paper describes Pleistocene limits of the Donjek Glacier and the distribution of surficial materials in the upper Quill, Maple, and Wade creek drainages. The source and transport mechanism of surface materials has particular significance for surficial geochemistry sampling programs and implications for mineral exploration are addressed.
