2014 Map of Alameda Flat

About this map

Osborne Corner serves as a small waypoint in this high-desert landscape, located just south of the Okanogan Co Douglas Co line. The terrain is defined by deep incisions and broad plateaus above the Columbia River, which flows through the northwestern corner of the sheet. Within the Colville Indian Reservation, the river passes over the Mah-kin Rapids near the expansive Saddle Horse Flat. The map reveals a complex network of local roads such as McIntosh NE Rd and Strahl Rex Rd that thread through the canyons, connecting remote points like Twin Springs Canyon and Buck Canyon. This 2014 survey documents the enduring physical character of the land, from the prominence of Wilson Butte in the south to the seasonal basins of Rattlesnake Lake and Wilson Lake, reflecting a region where topography dictates the flow of travel and the placement of rural outposts.
