History

Kelso originated in the 1880s near the mouth of the Cowlitz River during regional expansion tied to the Northern Pacific Railway and the Great Northern Railway. Early settlers included people associated with the Hudson's Bay Company fur trade routes and pioneers moving west along the Oregon Trail. The town’s growth accelerated with the arrival of logging companies such as those linked to the Weyerhaeuser Company and sawmills that processed timber harvested from the Cascade Range and the Gifford Pinchot National Forest. Kelso was incorporated in 1888 and later experienced development tied to the construction of bridges across the Cowlitz River and the Columbia River, linking to Longview, Washington and trade along the Pacific Northwest shipping routes. Throughout the 20th century, Kelso was affected by broader economic shifts documented alongside events like the Great Depression and wartime mobilization tied to shipbuilding at Vancouver, Washington. Natural events, including floods associated with the Columbia River Floods and seismic awareness after the 1964 Alaska earthquake, have influenced municipal planning and infrastructure.
