The northern Rocky Mountains, including parts of Montana, Wyoming, and Idaho, are apparent in this synoptic, southeast-looking photograph. The small dark blue area in the center of the photograph is Yellowstone Lake. Several snow-capped mountain ranges with elevations of more than 9000 feet (2700 meters) can be seen-the Absaroka Range east of Yellowstone Lake, the Big Horn Mountains east of the Absarokas, and the Wind River Range south of the lake. Using Yellowstone Lake again as a reference point, several major river basin areas are also visible—the Big Horn Basin is east, the Great Divide Basin is south, and the Snake River Basin is west. Other valleys and basins are interspersed between the smaller mountain ranges north and northwest of Yellowstone Lake. Agricultural field patterns are barely visible in many of the valleys.
