2011 Map of Snake River

About this map

The Snake River carves a deep path through the plateau in this 2011 topographic record, where the river's flow is punctuated by the broad waters of Lake Sacajawea. Small riverside clusters and junctions like Snake River Junction and Simmons highlight the historic importance of the river corridor for transportation and water access in an otherwise arid landscape. The topography is defined by sharp elevation changes as the high ground drops into McCoy Canyon and toward the banks of Lake Sacajawea Bar. Inland, a network of rural roads such as Pasco Kahlotus Rd and Walker School Rd connect isolated settlements like Burr, Walker, and Sheffler. These roads follow the natural contours of the land, tracing the edges of coulees and ridges that separate the river valley from the surrounding agricultural uplands.
