About this map

Lake Herbert G West and the Snake River dominate this 1981 topographic survey, marking the boundary between Franklin and Walla Walla counties. The landscape transitions from the river's Cow Bar and Skookum Canyon into upland agricultural and ranching territory. Settlement and industry are tied to the water and rail, with the Union Pacific line tracking the southern shore.

Evidence of local land use is visible at the Magallon Ranch, accessed via Magallon Road, and the southern Tucker Farm. The presence of a Quarry and various Borrow Pits near the water suggests ongoing infrastructure or railway maintenance. This map captures a specific moment in the Snake River's managed history, featuring navigation aids like Mile 45 and Mile 50 lights, alongside landmarks such as Monumental Rock.
