History

The area hosted indigenous peoples including the Cowlitz Indian Tribe and the Chinookan peoples, with cultural and trade links to the Lewis and Clark Expedition era routes and the Oregon Trail. Euro-American settlement expanded after treaties such as the Treaty of Point Elliott and events connected to the California Gold Rush, while early industry tied to the Hudson's Bay Company and the Pacific Fur Company fur trade. The county was formed during territorial reorganization concurrent with the Washington Territory period and experienced growth with the arrival of the Northern Pacific Railway and later the Great Northern Railway. The timber boom involved companies like Weyerhaeuser and incidents tied to labor movements such as actions influenced by the Industrial Workers of the World. Volcanic activity at Mount St. Helens produced the 1980 eruption that reshaped landscape and policy responses from agencies like the United States Geological Survey and the National Park Service.
