Mount Margaret is a 5,850-ft (1,780 m) mountain summit located in Mount St. Helens National Volcanic Monument, in the Gifford Pinchot National Forest, in Skamania County of southwest Washington state. It is situated in the Cascade Range, north of Spirit Lake, and northeast of Coldwater Peak. Its nearest higher neighbor is Mount Whittier, to the north, and Mount St. Helens rises to the south. Precipitation runoff from Mount Margaret drains into Coldwater Creek, a tributary of the North Fork Toutle River. A hiking trail provides access to this mountain. This peak was named some time before 1900 by an admiring prospector for Margaret Maggie Shultz Layton (1877-1965), a pioneering resident of Toledo, Washington.
