The Cowlitz region is in present-day southwest Washington State, and is named after
the Cowlitz, a Salish-speaking people who, upon European contact, shared this area
with numerous other tribes of varying populations.1 Cowlitz and the surrounding area was a nexus of British and US land disputes in the
mid-1800s and, amidst increased trade-rights rivalry, the Puget's Sound Agricultural
Company—ostensibly, the HBC—established a farm at the headwaters of the Cowlitz River,
which branches north from the Columbia River.2
James Douglas, then chief trader of the HBC, oversaw the formation of the Cowlitz farm in 1838,
as it was hoped that, after the ongoing boundary disputes between Britain and the
United States, the British would gain land north of the Columbia River.3 However, the Oregon Treaty of 1846 moved the British boundary to the 49th parallel.
