Cowlitz County is a county located in the U.S. state of Washington. As of the 2010 census, its population was 102,410. The county seat is Kelso, and its largest city is Longview. The county was formed in April 1854. Its name derives from the anglicized version of the Cowlitz Indian term Cow-e-liske, meaning either 'river of shifting sands' or 'capturing the medicine spirit.'

Cowlitz comprises the Longview, WA Metropolitan Statistical Area, which is also included in the Portland-Vancouver-Salem, OR-WA Combined Statistical Area.

History

Prior to the Europeans' arrival to the area, it was inhabited by numerous Native American tribes, with the Cowlitz tribe being the largest. They were drawn to the region by the abundance of salmon. The Cowlitz are considered to be the first regional inhabitants to engage in commerce as they traded extensively with other tribes in Western and Eastern Washington. The Cowlitz Indian population declined significantly from the 1829-1830 smallpox outbreak.

European explorers discovered and began navigating the Columbia River in 1792 as British Lieutenant W. R. Broughton sailed up the river to and past present day Cowlitz County. Then on November 5, 1805, Lewis and Clark camped at that mouth of the Kalama River, under orders from President Thomas Jefferson. Over the following days, they would reach the present sites of Kelso and Longview.

By the 1820s, the Hudson's Bay Company had established a lucrative fur trade in the region. Furs were shipped down the Cowlitz River to the Columbia where they were loaded and shipped around the world. Trade declined significantly in the late 1830s as over-hunting and fashions had changed.

During the next several decades, white settlement of the region was in full swing. Most of the settlers homesteaded around the number of tributaries that fed the Columbia River. It was during this era that the first settlements were established. The first was Monticello, near present-day Longview. In 1841 several families with the HBC directed Sinclair expedition from Red River Colony settled there.

This was the location of the Monticello Convention where a group of prominent settlers from the Cowlitz and Puget Sound regions met to draft a petition to the District of Columbia calling for a separate territory, to be carved out the Oregon Territory, north of the Columbia River. This convention took place on November 25, 1852 and three months later the United States Congress formed Columbia Territory, which was later known as Washington Territory. Being one of the first counties organized, it was created on April 24, 1854, by the newly formed Washington Territorial Government and signed into law by Governor Isaac Stevens.

Nearly every town that sprang up in the late 19th century began around a logging or lumber-milling operation. In the latter half of the 1920s, the Weyerhaeuser Company and Long-Bell Lumber Company established processing facilities. At the time, these two facilities were the first and second largest in the world. The county is still heavily dependent on the timber industry.

Four towns have claimed the Cowlitz County seat.

Cowlitz County is part of the Puget Sound – Willamette Depression, a geologic formation extending south from the Puget Sound to the Willamette Valley in Oregon. Nestled up against the Cascade Mountains, many of the county’s major rivers originate in this range. These rivers include the Columbia, Cowlitz, Coweeman, Kalama, Lewis and Toutle.
