Columbia River Plateau

The "Tri-Cities Area" consists of Kennewick, Richland, and Pasco, set at the confluence of the Yakima, Snake, and Columbia rivers.

Interstate 82 follows the Yakima River. Interstate 182 crosses the Columbia River. Interstate 84 follows the Columbia River to the south. The farmland consists of grapes, wheat, apples, and many other crops. The Rattlesnake Hills are to the south of the valley. Residents commonly use Highway 240, which is adjacent to the Columbia River, to travel between Kennewick, Richland, and Pasco quickly.

South of the Rattlesnake Hills is the Columbia River Gorge on the border with Oregon.
