The Largest OpenPit Mine in California | NASA
Much of the mine workings were underground until 1957, when US Borax changed to openpit mining. The open pit is clearly visible at center; concentric benches along the pit wall are accentuated by shadows and mark successive levels of material extraction. Mine tailings are visible as stacked terraces along the northern boundary of the mine.
