The Trump administration says its pause on border construction in Big Bend National Park will last at least through the end of the month, according to a Monday court filing. A local indigenous group and river outfitter are asking a judge to block construction across the region.

Those opposed to a border barrier through the Big Bend region say the Texas Parks and Wildlife Department should be doing more to stop the construction on state land.

In the coming months, the Trump administration’s construction of border barriers could impact hundreds, even thousands, of archeological sites in the Lower Pecos Canyonlands, where the Pecos River and Devils River join the Rio Grande

As the Trump administration moves forward with a border wall in the region, a local archeologist says early construction activities have already damaged a notorious historic massacre site in Presidio County. Descendants say the wall threatens to further erase a painful and undertold history they’ve worked for years to bring to light.
