Clark County, with its lower Columbia River bottom and benchlands,
and forested Cascade foothills, is located on the border of
southwestern Washington. The county was named after the U.S.
Army Officer, Captain William Clark, whose expedition descended
the Columbia River in November 1805. The area was organized
into Clark County by the Oregon Territorial government in
1956 bulletin from the County Agricultural Data Series created by NASS, then known as the Crop and Livestock
Reporting Service. Links are to different chapters within the bulletin and are in Adobe PDF format.
