Mount Tom is a remote 7,076-foot peak in Olympic National Park west of Mount Olympus, with runoff flowing into tributaries of the Hoh River. Though not especially high, it supports the White Glacier on its northeast slope because the western Olympics receive exceptionally heavy winter snowfall. The glacier is the westernmost in the contiguous United States, and the mountain is the westernmost summit above 7,000 feet. Its naming is disputed: the Seattle Press Expedition called it Mount Reid in 1890, while the present name is linked either to surveyor Thomas M. Hammond Jr. or to Thomas Martin, a Boy Scout associated with a 1914 ascent led by Edmond S. Meany.
