The original people of the region were the Chemnapum Indians (closely related to the Wanapum tribe), living near the mouth of the Yakima River. Lewis and Clark passed through the area in 1805, and an expedition of the Army Corps of Topographical Engineers headed by Robert E Johnson mapped the Yakima Valley in 1841.
