Mount Tom is a remote mountain summit located within Olympic National Park in Jefferson County of Washington state. Its nearest higher neighbor is Mount Olympus, to the east. Due to heavy winter snowfalls, Mount Tom supports the massive White Glacier on its northeast slope, despite its modest elevation. This glacier is the westernmost glacier in the contiguous states, and the summit is the westernmost peak higher than 7000+ feet elevation. Precipitation runoff from the mountain drains into tributaries of the Hoh River.
