Ancient Rock Art is Reborn at Hueco Tanks State Park, Texas

When it comes to rock art, Hueco Tanks, east of El Paso, is in a class by itself with rock art that dates back 6000 years. Unfortunately, over the years some of the pictographs have been damaged by graffiti. But now a new type of laser technology is about to turn back time. It's a laser light show that wipes away the graffiti but doesn't affect the pictograph underneath. For more on Hueco Tanks State Park, see www.tpwd.state....
