Antiquities Act Monuments

This dataset contains information on national monuments designated under the U.S. Antiquities Act.

It includes data on each monument's name, the president or congress who designated it, the year of designation, the state(s) in which it is located, the total area protected, and whether the monument was later expanded or reduced in size.

This dataset can be used to analyze trends in the use of the Antiquities Act over time, including the geographic distribution of protected areas and presidential actions related to conservation.
