The U.S. Department of the Interior is proposing to revoke protections that prevent mining and drilling on land surrounding the Chaco Culture National Historical Park in New Mexico. This move comes as Western water leaders prepare to gather in Las Vegas to negotiate a new agreement on the Colorado River, with tribal leaders insisting they want a say in the final deal.

Why it matters

Chaco Canyon is a UNESCO World Heritage site and holds deep cultural significance for several Native American tribes in the region. Revoking the current protections could open up the area to extractive industries, threatening the integrity of the archaeological sites and the tribes' connection to the land.
