Earth from Space - Image Description

STS61A-34-0025 Lake St. Francis, Quebec, Canada November 1985
Located approximately 50 miles (80 kilometers) south of Quebec City, the Thetford Mines (a town and also the name given to the mining site) are visible in the center of the image (lighter color areas). These asbestos mines produce a large share of the world's supply. The lighter shaded areas within an otherwise forested landscape (darker areas) shows the extent to which the trees have been removed in this region either to expand available farm land or to furnish trees to the forestry industry. The elongated, dark feature (bottom center) is Lake St. Francis. Lake Aylmer (another dark feature--lower left) is southwest of the large lake. Lake Williams is the much smaller linear lake located north of the Thetford Mines site.
