The "Northern Arizona Protection Act" proposes to invalidate Presidential Proclamation 10606 , which established the Baaj Nwaavjo I'tah Kukveni-Ancestral Footprints of the Grand Canyon National Monument on August 8, 2023. If enacted, this bill would ensure that the proclamation has no legal force or effect, thereby disestablishing the national monument and reversing the withdrawal of certain Arizona land from mineral entry. Furthermore, the legislation introduces a significant restriction on future land designations within the specified Grand Canyon area. It explicitly prohibits any subsequent extension or establishment of national monuments in the region without the express authorization of Congress , limiting the executive branch's power under the Antiquities Act for this particular area.
