Next we hiked in to an abandoned Calcite Mine. It was used for optical calcite for gun sights in WWII and run by the Polaroid Corporation. It was closed after only a short time due to a newly created synthetic substitute.
There is a high difficulty 4x4 road that goes all the way to the mine, but we couldn't do it in our stocker. Instead we enjoyed a nice hike. On the return we explored a really cool side slot canyon and came back down Palm Wash.
Still tire tracks back here - a good jeep with a skilled driver could probably make it fine - this stretch is still in pretty good condition, it's the stuff between the pavement and the mine that gets tricky.
Climbing out of the wash and back to the road.
After this hike we headed up to Palm Springs for the night - needed to resupply, get some good food and a shower, and recharge for the rest of the week in Joshua Tree!
