The snow capped Canadian Rocky Mountains provide a dramatic contrast against the reddish (actually green forests) tree covered slopes of the numerous canyons along this section of the Columbia River just north of Revelstoke in this color infrared image. At the time that the picture was taken snow cover on the higher elevations generally exceed 9000 feet (2740 meters) above sea level. The angular shaped lighter colored pattern on many of the mountain slopes and in some of the valleys map the areas where trees have been removed as part of the large lumber industry found in British Columbia.
