1989 Map of Alameda Flat

About this map

Alameda Flat and the surrounding high plateau of northern Washington define this 1980s landscape, just south of the Columbia River and Rufus Woods Lake. The map illustrates a transitional geography between the expansive Colville Indian Reservation across the water and the agricultural lands of Douglas Co. Small settlements like Alameda and the rural junction at Osborne Corner are isolated amidst a terrain carved by deep drainages, most notably Strahl Canyon and Twin Springs Canyon. This late-century survey captures the region's scattered water sources, documenting Rattlesnake Lake, Wilson Lake, and various springs that supported ranching and dryland farming on the flats. Landmarks such as Balloon Rock and Wilson Butte provide distinct orientation points in a territory where the boundaries of Okanogan Co meet along the river's winding path.
