STS028-072-054 North Saskatchewan River, Alberta, Canada August 1989 White, snow capped peaks visible towards the bottom of the image exceed 10000 feet (3050 meters) above sea level in this section of the Canadian Rocky Mountains west of Red Deer. Many deeply incised streams and valleys present a spectacular appearance in this mountain setting. The darker valley areas are the result of topographically lower, forested slopes. Highway 11 is visible as a light-colored, linear feature along the north (left) side of the river near the center of the image. Several tributary streams can be seen flowing into the North Saskatchewan River (center of image) as it flows northeast (upper left) through the mountains.
