Plan to build border wall along the Rio Grande in Texas threatens prehistoric rock art, locals warn

Plans to extend the US-Mexico border wall through Val Verde County, Texas, threaten to damage or destroy hundreds of prehistoric rock art murals in the Lower Pecos region. Archaeologists and local landowners warn that construction vibrations could destabilize the rock surfaces housing these ancient paintings, some of which are over 5,700 years old and span up to 100 feet in length.
