Cathedral Peak is an 8,606-foot mountain in Washington’s Okanogan Range, within the North Cascades near the Canadian border. Rising above Cathedral Pass in the Pasayten Wilderness, it stands on a high divide where water flows west to Cathedral Fork and east to Cathedral Creek. The peak and surrounding landscape reflect the North Cascades’ long formation through tectonic, volcanic, and terrane-building processes, later sharply sculpted by repeated Pleistocene glaciation. Cathedral Peak is also a noted climbing destination, with established routes on the South Face, Southeast Buttress, and Northeast Ridge, including the South Face ascent first completed in 1968 by Fred Beckey and party.
