COMSTOCK, Texas — A complex colorful mural painted on canyon walls some 4,000 years ago in West Texas is getting modern laser treatment as researchers try to unlock its mysteries and protect it from the unintended consequences of a nearby reservoir
Panther Cave, among the best known of several hundred prehistoric pictograph sites that dot the rugged canyons along the US-Mexico border, is being scanned with lasers to produce a high-resolution 3-D image in efforts to gauge the mural's deterioration and detect images long ago erased by Mother Nature. They hope the project will help them preserve and decipher one of the oldest stories in North America.
