Hueco Tanks, Texas State Historical Park

We finally made it to Hueco Tanks on this trip.  Not an easy visit, as you first have to get a permit, of which only 70 are given out per day, and then you can make a camping reservation.  Why all of the bureaucracy?  To protect these incredible pictographs that date from thousands of years ago, to the ancient people, to the Apaches, to the mid 1800 pioneers heading west for the Gold Rush.

Our guided tour, lead by a couple of excellent docents, took us up on the mountains to show us many of the pictographs.  We saw drawings from the ancient Fremont Indians, the Hopi, the Apaches, and the stage coach travelers on their way out to the west coast to seek their fortune in gold.

  

Following the tour, we struck out on our own, with our daily permit in hand, up the chain trail.  We saw even more pictographs.  Colors of red, yellow, black, and white were used; all brought into the area as none of the local rocks and minerals would present in these colors. 
All quite fascinating.
