Chromite mining The Oregon Encyclopedia

Evidence of mining in the form of primitive roads, pits, tunnels, cabins, and mills can still be found on the landscape, including in the Kalmiopsis Wilderness. While the United States has imported all its chromite since 1961, the Oregon Resources Corporation proposed to mine the black sands near Coos Bay.
