We’re not talking about music here, but Native American Rock Art at sites such as Hueco Tanks in El Paso County, deeded this day in 1969 to the Texas Parks and Wildlife Department and reopened to the public 11 months later as the Hueco Tanks State Historical Park.

Indian rock art decorates the granite hills that rise 450 feet above the desert east of El Paso. The site takes its name from the hollows (“hueco” in Spanish) where rainwater collects. Because for thousands of years this was the only water source in the region, native tribesmen frequented the site, chipping arrowheads and drawing some 5000 pictographs and petroglyphs.
