Buck Mountain is an 8,534-foot peak in Washington’s North Cascades, within the Glacier Peak Wilderness and Wenatchee National Forest. Set among rugged terrain and draining into tributaries of the Wenatchee River, it reflects the long geological history of the range, from terrane accretion about 50 million years ago to later volcanic development and repeated Pleistocene glaciation that carved deep U-shaped valleys. Several glaciers remain on its slopes, underscoring its alpine character. The name was given by Albert Hale Sylvester, who named many Cascade places in the early twentieth century. Shaped as well by a wet maritime climate, the mountain is valued for its remoteness, sharp relief, and glacial scenery.
