About this map

Okanogan National Forest defines this high-elevation landscape, where the headwaters of the Lost River and Monument Creek carve through the Pasayten Wilderness area. The topography is dominated by a series of dramatic summits and ridges, including the central Lost Peak and the southern Pistol Peaks. This 2020 survey illustrates a complex hydrologic network of alpine basins, such as those containing Lake of the Woods and Johnny Lakes, which feed the drainages of Rampart Cr and Billy Cr.

The map reveals a terrain shaped by steep elevation gradients, from the sheer faces of Rampart Ridge to the high saddles of Lucky Pass and Pass Butte. Named landmarks like Many Trails Peak and Nanny Goat Mtn suggest a long history of human and animal movement through these subalpine zones. The document provides a detailed record of water features such as Hidden Lakes and Diamond Cr, essential for modern conservation and historical land use studies in this part of Washington.
