About this map

Snake River geography dominates this modern survey of the border between Franklin and Walla Walla Counties. The map focuses on the impounded waters of Lake Sacajawea, a significant reach of the river where steep-sided terrain like Burr Canyon and McCoy Canyon meets the water's edge. This landscape reflects the modern management of the Columbia River Basin's waterways, where older river bars like Lake Sacajawea Bar are now part of a regulated reservoir system.

Small riverfront landings and rail-side points such as Burr, Walker, and Sheffler are visible along the eastern bank. The Columbia Plateau State Park Trail follows the former railroad grade along the river, providing a historical through-line for the region's transportation. The uplands are defined by a network of rural roads including Pasco Kahlotus Road and Jones Rd, serving the agricultural plateaus that rise sharply away from the canyon floor.
