Pyramid Peak is a 7,189-foot summit in Washington’s North Cascades National Park, rising above Diablo Lake and the Skagit River along a chain of peaks extending south toward Colonial Peak and Snowfield Peak. Its significance lies in its dramatic local relief rather than sheer height, climbing about 6,400 feet above the Skagit River in only 2.5 miles. Water from the mountain drains into Diablo Lake and the river below. First climbed in 1931 by William Degenhardt and Herbert Strandberg of the Seattle Mountaineers, the peak also reflects the broader geologic forces and marine west coast climate that shaped the rugged North Cascades.
