STS-61A earth observations

61A-200-152 (30 Oct-5 Nov 1985) --- Sun glints on the small and very numerous glacial lakes of the Canadian Shield of Quebec. This is an area of very ancient pre-Cambrian rock, which uplifted when the weight of the Pleistocene glaciers was removed. The double crescent lake is Lake Mistassini, some 400 miles north of Montreal.
