About this map

The Similkameen River carves a path through the high country of Okanogan County, anchoring a landscape where narrow valleys meet prominent peaks. Near the northern border, the settlement of Nighthawk sits along the river, connected to the broader region by the Loomis Oroville Rd. This area is defined by sharp elevation changes, from the depths of Chopaka Valley to the summits of Chopaka Mtn and Grandview Mtn.

Hydrographic diversity is evident in the contrast between the freshwater of Palmer Lake and the unique mineral features of The Salt Lakes and Alkali Flat. Modern recreation and traditional travel routes intersect here, with the Pacific NW National Scenic Trail winding through the western and southern reaches of the quadrangle. The map also documents the seasonal water patterns of the lowlands, including Humphreys Slough Stream and Edwards Slough, which feed into the wetlands surrounding the river and lakes.
