The Chaco Cultural Heritage Area Protection Act of 2025 aims to safeguard certain federal lands in New Mexico, particularly around the Chaco Culture National Historical Park. The main goal is to protect the area's archaeological, cultural, and historical resources, which are significant to various Indigenous tribes and the broader community. Key provisions of the Act include the withdrawal of federal land from various forms of development, such as oil and gas leasing, mining, and other land appropriations.
