Riddle Peaks, also known as Riddle Peak, is an 8,212-foot (2,503-metre) mountain summit located at the head of Riddle Creek in the North Cascades, in Chelan County of Washington state.^[1] Riddle Peak is situated on the Glacier Peak Wilderness boundary, six miles west of Lake Chelan, and 2.5 mi (4.0 km) northeast of Holden, on land managed by the Wenatchee National Forest. The nearest higher neighbor is Flora Mountain, 2.25 miles (3.62 km) to the northeast, and Martin Peak lies 3.7 miles (6.0 km) to the west-northwest.^[2] Precipitation runoff from the mountain drains into Lake Chelan via Railroad Creek, Riddle Creek, and Devore Creek. Topographic relief is significant since the southern aspect of the mountain rises 5,000 feet above the Railroad Creek valley in approximately 2 mi (3.2 km). The first ascent of the peak was made September 11, 1940, by Everett and Ida Zacher Darr, Joe Leuthold, and Eldon Metzger via an easy ridge from Tenmile Pass.^[4]
