Image depicts the river which runs through Miles Canyon, located near Whitehorse Y.T.

File contains slides depicting locations along the White Pass railway through Alaska, British Columbia, and the Yukon Territories.

In July 2009, Dr. Paul Sanborn undertook the first soils field research at the Fort Selkirk volcanic field in central Yukon, with helicopter support and funding from the Yukon Geological Survey. This file consists of prints of aerial photographs that depict the area accessed for the study, upstream from the confluence of the Yukon River and the Pelly River.

Air photographs include:
Flight line A17210, Photo Nos. 54-60 (taken 1960)
Flight line A22354, Photo Nos. 43-45, 47-48 (taken 1971)
Flight line A27516, Photo Nos. 48-52 (taken 1989)
