2020 Map of Silcott Island

About this map

The Snake River carves a deep path through this portion of the Pacific Northwest, where the borders of Whitman, Asotin, and Garfield counties converge at the water's edge. This modern survey illustrates the rugged river topography south of the Steptoe Canyon area, focusing on the small settlements of Silcott and Moses. A significant landmark in this riverine landscape is the Indian Timothy Bridge, which facilitates movement across the drainage near where Alpowa Cr meets the main channel. High elevation features like Flerchinger Ridge and numerous steep drainages, including Maguire Gulch and Sheep Gulch, define the surrounding canyon walls. The map reveals how local infrastructure like Silcott Grade Rd and Wawawai River Rd navigate the complex elevation changes between the river basin and the high plateau above.
