The bill H.C.M. 2008 urges the U.S. Congress and the President to repeal or amend the Antiquities Act of 1906, which currently allows the President to establish national monuments on federal lands. The proposed changes emphasize that entire landscapes and common plants should not be classified as landmarks or objects under federal law. Additionally, it calls for any presidential proclamations regarding national monuments to specifically name and describe the locations of the landmarks being protected.

Furthermore, the bill seeks to limit the establishment or expansion of national monuments in Arizona without express authorization from the Arizona State Legislature and the county boards of supervisors in affected areas. It also requests that the Secretary of State transmit copies of this memorial to key federal officials. Overall, the new bill language introduces specific requirements and limitations regarding national monuments that are not present in the current law.
