U.S. federal contractors are constructing new border wall sections, including on Kuuchamaa Mountain, after the Department of Homeland Security waived cultural and environmental laws. The work has inadvertently disturbed ancient sites, prompting tribal nations to lobby against construction on their lands. Customs and Border Protection has awarded contracts or begun construction on over 600 miles of new wall and surveillance technology.
Facts First
- Construction crews worked on a new border wall segment on Kuuchamaa Mountain in April 2026.
- The Department of Homeland Security waived cultural and environmental laws to facilitate barrier construction.
- A contractor inadvertently disturbed a 1,000-year-old geoglyph in Arizona's Cabeza Prieta National Wildlife Refuge.
- Tribal representatives met with Homeland Security Secretary to lobby against wall construction on their lands.
- Contracts or construction have begun on over 600 miles of new border wall and surveillance technology.
What Happened
Construction crews worked on a new border wall segment on Kuuchamaa Mountain on Friday, April 24, 2026. U.S. federal contractors have been blasting and bulldozing Kuuchamaa Mountain, which straddles the U.S.-Mexico border, to build new wall sections. The U.S. Department of Homeland Security (DHS) waived cultural and environmental laws, which facilitated much of the recent barrier construction along the 1,954-mile border. In April 2026, DHS contractors carved through 'Las Playas Intaglio,' a 1,000-year-old fish-shaped geoglyph located on a lava field in the Cabeza Prieta National Wildlife Refuge in Arizona. U.S. Customs and Border Protection (CBP) stated that a contractor 'inadvertently disturbed' the Las Playas Intaglio site west of Ajo, Arizona, on April 23.
Why this Matters to You
This construction activity may affect the preservation of historic and sacred sites along the border, including Kuuchamaa Mountain, which was listed in the National Register of Historic Places in 1992. Desecrating a sacred Native American site on U.S. federal or tribal land is a felony. The waivers of cultural and environmental laws could limit public oversight and legal recourse regarding construction impacts. If you are a member of a border community or tribal nation, this construction could directly impact your land, cultural heritage, and environment.
What's Next
Members of the Inter-Tribal Association of Arizona... met with Homeland Security Secretary Markwayne Mullin in Washington last month to lobby against a 20-foot secondary wall and a 30-foot bollard wall on Tohono O’odham tribal lands. CBP is seeking to seize a strip of land on Mount Cristo Rey owned by the Roman Catholic Church; the Diocese of Las Cruces requested a judge deny the land transfer this month. In February 2026, the federal government notified ranchers on the Rio Grande... of its interest in land containing canyonland pictographs and petroglyphs. CBP has stated that 535 miles of remote, rugged border terrain will rely solely on detection technology, and in one specific area, it scrapped 30-foot-wall plans following community backlash, opting instead for surveillance technology, patrols, and vehicle barriers.
