Okanogan National Forest dominates this high-altitude landscape in northern Washington, centered on the prominent heights of Corral Butte and Windy Peak. The terrain is defined by a complex network of high mountain drainage systems, including Twentymile Cr, Thirtymile Cr, and the various forks of Toats Coulee Creek. This 2017 survey details the access routes through these remote elevations via Nat For Dev Rd 39 and Toats Coulee Rd. Several significant high-country clearings are noted, such as Thirtymile Meadows and North Twentymile Meadows, which provide critical open space between the peaks of Thunder Mtn and the crossing at Honeymoon Pass. The map captures the hydrographic patterns of the Pasayten Wilderness periphery, where dozens of small streams like Smarty Cr and Crosby Cr feed into larger tributaries.
