About 32 miles east of El Paso, this 860-acre park contains three small granite mountains that are pocked with depressions (hueco is Spanish for ‘hollow’) that hold rainwater, creating an oasis in the barren desert. The area has attracted humans for as many as 10,000 years, as evidenced by pictographs. Park staff estimate there are more than 2000 pictographs at the site, some dating back 5000 years.
