On April 11, 2023, Coconino County Chair Patrice Horstman and District 5 Supervisor Lena Fowler, joined eleven tribal leaders of the Grand Canyon Tribal Coalition, alongside Congressman Raúl M. Grijalva (D-Ariz.) and Senator Kyrsten Sinema (I-Ariz.), to launch an effort to call on President Joe Biden to use his authorities under the Antiquities Act of 1906 to designate the Baaj Nwaavjo I’tah Kukveni Grand Canyon National Monument.
The Monument designation would protect 1,102,501 acres adjacent to the Grand Canyon by making the current 20-year moratorium on mining permanent across the vast landscape of the Grand Canyon region.
