Geology
editIn 1945, the State of Oregon Department of Geology and Mineral Industries researched the composition of the Salem Hills, and found bauxite.[3] At the time, there was an expectation that the post-war demand for aluminum would decrease, so additional study into the area was not done.[3] In 1953, as demand for bauxite continued to grow, there was an additional survey done, which found that basaltic lava created the deposits of ferruginous bauxite, believed to be of the Miocene age.[3] The area was never mined.[4]
