1989 Map of Thrapp Mtn

USGS Topo · Published 1989

About this map

The Red Shirt Mine and several surrounding prospects stand at the western edge of this rugged highland landscape, marking the extractive history of the Methow Valley area in the late 1980s. This territory is dominated by the Okanogan National Forest, where steep drainages like Finley Canyon and Benson Creek carve through the Okanogan Highlands. The elevation is defined by a series of prominent peaks and ridges, including Thrapp Mtn, Pole Pick Mtn, and the high point of Mt Leecher in the southwest. A network of primitive trails and unimproved roads connects isolated water sources such as Wenner Lakes to the more significant watercourses like Frazer Creek and the South Fork Benson Creek. The map provides a detailed view of the drainage patterns and topography used by foresters and miners before modern developments altered these backcountry routes.
