Yuma Proving Grounds Camping

People dry-camp (no utilities) all over the desert, but they have to get permission from the Bureau of Land Management first.  Since it's near the proving ground, there are certain days in certain areas that the military for training.  There are several units that are apparently staying the whole winter.  You can see one of them with solar panels on top, and even a windmill for energy!

I was amazed to hear about and see that there are marsh lands in the desert!
