Adams County Spotlight

Adams County

Established in 1883, Adams County is located in the southeastern corner of Washington State. One of Washington’s primary wheat producers, the economy of Adams County is based in a diverse array of industries, including agricultural production, livestock, and economical energy. While the eastern section of the county produces primarily dry crops, such as wheat, canola, camelina, and other grains, the western part of the county produces a wider variety of crops, such as apples, potatoes, and beans.

Although agriculture remains the foundation of Adams County’s economy, the county is also home to a plethora of unique geographical features, including basalt formations, volcanic craters, and coulees created by Ice-Age floods, making it an attractive place for outdoor tourism.
