Washington · Southwest Washington · Columbia River · Mount St. Helens Gateway

Cowlitz County, Washington

Mount St. Helens' primary gateway and Longview's planned city — from the 1980 eruption's mudflows that traveled down the Cowlitz River to devastate communities here to Longview's extraordinary 1920s planned industrial city built entirely by the Long-Bell Lumber Company, and a Southwest Washington county where Columbia River industry, volcanic history, and Pacific Northwest timber traditions define a genuine working community.
