President Trump's border wall is putting archaeological discoveries at risk before they're even discovered.

Trump's border wall has jeopardized several government projects as he aims to drain military projects to fund its construction. It has raised protests from environmental groups who say it'll run through wildlife refuges. And as an internal National Park Service report obtained by The Washington Post reveals, it's likely to destroy or damage 22 unexcavated sites containing artifacts of the ancient Sonoran Desert peoples.

The sites in question are all within the Organ Pipe Cactus National Monument, a 330,000-acre area of protected wilderness that sits along the Arizona-Mexico border. It has been home to "desert-dwelling peoples" for at least 16,000 years and contains well-preserved artifacts thanks to its arid environment, the Post reports. There's currently a five-foot vehicle barrier along that section of the border, but Trump plans to turn it into a 30-foot steel wall. Two miles of that wall surrounding a border crossing in Lukeville, Arizona have already been built.

In its report, the National Park Service says some archaeological areas have already been damaged as the Trump administration's amped-up enforcement measures lead border patrol agents to drive recklessly through Organ Pipe Cactus. If construction continues, experts warn damage could get even worse. The several salt springs in the monument area could also dry up if groundwater is pumped to build the concrete wall, NPS continued.

CBP said it looked at "most" of the archaeological sites in question and said just five are within 60 feet of the proposed border area, and that only one showed signs of artifacts buried nearby. Read more at The Washington Post, and find the whole report here. Kathryn Krawczyk
