- Benton County — Thumbnail History (historylink.org)
Benton County is located in the southeastern portion of Washington state at the confluence of the Columbia, Snake, and Yakima rivers. The land, part of the semi-arid Columbia Basin, lies in the rain shadow of the Cascade Mountains and is naturally dry. But the soil is fertile and supports native plants such as bunch grasses and sagebrush.
