Casa Grande Ruins National Monument Boundary Modification Act of 2021 STATEMENT OF MICHAEL A. CALDWELL, ACTING ASSOCIATE DIRECTOR, PARK PLANNING, FACILITIES, AND LANDS, NATIONAL PARK SERVICE, U.S. DEPARTMENT OF THE INTERIOR, BEFORE THE SENATE ENERGY AND NATURAL RESOURCES SUBCOMMITTEE ON NATIONAL PARKS, REGARDING S. 1321, A BILL TO MODIFY THE BOUNDARY OF THE CASA GRANDE RUINS NATIONAL MONUMENT, AND FOR OTHER PURPOSES. JUNE 23, 2021 Chairman King, Ranking Member Daines, and members of the Subcommittee, thank you for the opportunity to present the views of the Department of the Interior on S. 1321, a bill to modify the boundary of the Casa Grande Ruins National Monument, and for other purposes. The Department supports S. 1321. Casa Grande Ruins National Monument, located in Coolidge, Arizona, was set aside as the first Federal archaeological reservation in the United States on June 22, 1892, by President Benjamin Harrison, and was established as a national monument on August 3, 1918, by President Woodrow Wilson by presidential proclamation. It consists of approximately 473 acres of land that contain numerous resources closely associated with the Hohokam culture, including the remnants of the Casa Grande, the great house, constructed in the 14th Century. S. 1321 would authorize the Secretary of the Interior to acquire from willing sellers approximately 406 acres of land for addition to Casa Grande Ruins National Monument. Approximately 146 of those acres are owned by private landowners along the monument’s western boundary and include a prehistoric canal and other archaeological sites identified by affiliated tribes. An additional 60 acres, to the east of the monument, are owned by the Archeological Conservancy. The remaining 200 acres are non-contiguous State of Arizona trust lands that contain above-ground prehistoric standing ruins as well as a prehistoric ball court. Given the excellent preservation of archaeological resources, the state site is an ideal location for visitor use and interpretation. As an alternative to acquiring the State lands, the Secretary would be authorized to enter into an agreement with the State to cooperatively manage the State land. In addition, S. 1321 would provide for several relatively small land transfers among three Departmental bureaus for more efficient and effective administration of land in the vicinity of the monument. The bill would transfer approximately 7.41 acres of land from the Bureau of Indian Affairs and approximately 3.8 acres of land from the Bureau of Land Management to the National Park Service. This transfer would provide broader opportunities to interpret the significant resources. And, 3.5 acres of land from the National Park Service and 3.7 acres of land from the Bureau of Land Management along the monument’s southern boundary would be transferred to the Bureau of Indian Affairs, which would allow the Bureau of Indian Affairs to widen and pave part of the Pima Lateral Canal and rationalize boundaries among the three bureaus. Lands transferred to the monument by this legislation and any lands acquired pursuant to this legislation would be administered as part of the monument, and the boundary of the monument would be adjusted accordingly. Mr. Chairman, this concludes my statement. I would be pleased to answer any questions you or other members of the Subcommittee may have.
