This is Tinajas Altas or high tanks as seen from where we parked. The tanks are natural water catch basins eroded out of the rock. There are a series of tanks, one above the next. They fill from the top down so the bottom tanks fill up last and empty first. There are stories of bodies being found here dead after having found the bottom tank empty and climbing up to higher tanks finding each one also empty. The irony is they were found within feet of an upper tank that had water.
This grinding stone is near the bottom tank and is evidence of people using the area for hundreds of years.
The water tasted...well...magical.
Just kidding, there was no way I was drinking it. It was full of muck and creepy crawlies.
