Columbia County is a 860-sq. mile county in southeast Washington state; bounded on north by Whitman county, on east by Garfield county; on south by Oregon and on west by Walla Walla county. It is devoted principally to production of wheat, peas and wool. On November 11, 1875, the county was established by the Territorial Legislature through the influence of delegate Elisha Ping. The Territorial governor had  previously vetoed a bill which would have named the county for Ping. The name chosen was that after that of Columbia River. The are had previously been part of Walla Walla county. The county seat is at Dayton, which is also the county's largest city.
