Snowmobiling in the Bischoffs
Was out exploring the north-east of Adams Lake this weekend.
Pictures of the day: here.
My guess is the area just right of centre on the map is an approximation of the glacier and peaks. The lakes at centre appear to be the "Bischoff Lakes". I'm not sure which range is the area we were sledding in, but it's somewhere near to those map coords (51°34' W, 119°02' N).
