Lexington Tower is a 7,560-foot granite pinnacle in Washington’s North Cascades, about a mile south of Washington Pass in the Okanogan–Wenatchee National Forest on the Okanogan-Chelan county line. Part of the Liberty Bell Group, it is known for rising abruptly roughly 2,500 feet above Early Winters Creek in about half a mile, creating the dramatic relief typical of the Washington Pass area. Formed from granite of the Golden Horn batholith, it stands in a landscape shaped by tectonic activity and Pleistocene glaciation. A recognized climbing objective, it was first ascended on July 5, 1954, with later routes increasing its prominence and difficulty.
