Mojave Desert

Joshua Tree Joshua Trees line the road in the Mohave desert between Pharumph and Vegas. Rio Tinto's borax mine, Boron, CA. Borax open pit mine. Notice the number of levels. DSC00573 At the entrance to the Rio Tinto visitors center is a reproduction of the Twenty Mule Team used for hauling borax out of the desert in the 1800s. It is hard to see the team and wagon, just below the small wind turbines, because of the lack of contrast between the rocks behind and the mule team and wagon. See next picture.
Maybe easier to see here are the mule team pulling wagons with borax followed by a wagon carrying a large water tank.  Hopefully cropping, re-scaling and and changing color levels help visualization from last image. Flying over the borax mine were fighters from nearby Edwards AFB. Fighters in formation leaving contrails across the sky.
