A Night Begins in Wyoming

Evening twilight fades to a starry night above the Grand Teton National Park in Wyoming. In the sky constellation Leo is on the left (west) and Cassiopeia is on the right (north). In the background is the Teton Range, a part of the Rocky Mountains. The Grand Teton, the tallest mountain in the range, is 13,775 feet (4,199 m) high.
