Today’s Hanford was once north of Tulare Lake, historically the largest body of fresh water west of the Mississippi River. The area was inhabited by the Tachi Yokut Indians for several thousand years prior to Euro-American contact. They occupied locations along watercourses such as creeks, springs and seep areas (such as sloughs), along perennial and seasonal drainages, as well as flat ridges and terraces. Therefore, places along streams are considered likely locations for prehistoric cultural resources. Permanent villages were usually placed on an elevation above the seasonal flood levels. Surrounding areas were used for hunting and seed, acorn, and grass gathering. Since the annexation of California after the Mexican-American War, the locality was settled by Americans and immigrants as farmland, broadly referred to as “Mussel Slough”.
