This panoramic, southwest-looking, low-oblique photograph shows many small mountain ranges that comprise the Rocky Mountains of southwestern Montana and eastern Idaho. Visible are the southern half of Canyon Ferry Lake (bottom center); to the southeast, the snow-covered mountains of northwestern Yellowstone National Park and a small portion of ice-covered Yellowstone Lake; and to the west and southwest, the eastern portion of the Snake River Plain within which lie the dark black lava flows of Craters of the Moon National Monument. Northwest of the Snake River Plain the southern portion of the Bitterroot Range is discernible.
