Chelatchie is an unincorporated community in Clark County, Washington.
Chelatchie is located about northeast of Vancouver, Washington in the Chelatchie Prairie (or Chelatchie Valley) area, and consists of several homes, a general store, and a United States Forest Service visitor center for the Mount St. Helens Volcanic National Monument. It is one of the more remote communities on Washington State Route 503, and serves as a gateway into the Siouxon Creek area of the Gifford Pinchot National Forest.
The area was first settled around 1860, and was among the first settlements in the area.[1] The name was derived from "ch'álacha,"[2] a Klickitat word describing a valley with tall ferns.[3]
The Chelatchie Prairie Railroad was extended to the area in 1948, with the International Paper Company opening a plywood mill at the end of the line in 1960,[4] which operated until 1979.
