It now appears that plans for a physical border wall through the heart of Big Bend National Park will not happen following pushback from local officials, residents, and conservation groups.
Updates to the U.S. Customs and Border Protection (CBP) maps show that the physical steel barrier previously slated for the park has been replaced with high-tech sensors and surveillance cameras rather than 30-foot steel fencing.
Sheriffs from Presidio, Brewster, Culberson, Hudspeth, and Terrell counties had released a joint statement opposing a continuous physical wall, arguing that the rugged canyons and mountains already provide natural security. Local leaders in Alpine, Marfa, and Terlingua have expressed deep concern that a wall would "devastate" the region's $60 million-a-year tourism economy.
While both the federal and state Big Bend parks appear safe from a physical wall, areas to the east and west will likely have one and work could begin as soon as June of this year.
