Mount Larrabee is a prominent seven thousand eight hundred sixty-five-foot summit in Washington’s North Cascades near the Canada–United States border, known for the reddish color created by iron oxidation in its phyllite and greenstone rock. Once called Red Mountain, it was renamed in nineteen fifty-one for Charles F. Larrabee, and the new name was officially adopted that year by the U.S. Board on Geographic Names. Its ridges include the jagged spires called The Pleiades, and an unnamed glacier lies below its steep north face. The mountain also bears traces of early nineteen hundreds mining and is valued today for wilderness scenery, broad views, and climbing access.
