The Trump administration's plan to expand border wall construction in west Texas, backed by $46.5 billion in federal funding, threatens thousands-year-old Indigenous rock art murals in the Lower Pecos Canyonlands. Customs and Border Protection has begun building vehicle barriers and patrol roads through Seminole Canyon State Park, home to 27 ancient murals, despite opposition from archaeologists, local residents, and political leaders. CBP recently halted bulldozing near Big Bend National Park's Santa Elena Canyon after activists publicized videos of the construction damaging the wilderness.
