Sleeping Beauty is a 4,907-foot (1,496 m) mountain summit located in the Gifford Pinchot National Forest of Skamania County in Washington state. It is situated in the Cascade Range, southwest of Mount Adams. Sleeping Beauty is so named because its profile as seen from the east side of the Trout Lake Valley somewhat resembles a sleeping woman. Precipitation runoff from Sleeping Beauty drains into tributaries of the White Salmon River. The peak is composed of andesitic magma that intruded up into older volcanic rocks more than 25 million years ago and is now surrounded by a forest of old-growth Douglas fir and mountain hemlock. Sleeping Beauty Peak Trail is a 1.4 mile steep trail that ends at the base of the rock outcrop known as Sleeping Beauty. The peak was the site of a former fire lookout tower that was constructed in 1931.
