Locke Island is an island located in the Hanford Reach of the Columbia River in Washington, United States. The island is protected as part of the Hanford Reach National Monument, which was created out of lands surrounding the Hanford Site.[2] The island is an important archeological site and is on the National Register of Historic Places. These cultural resources are being threatened by erosion resulting from a landslide changing the river's course.[3]
