United States National Monuments are regulated by the Federal Antiquities Act. They are managed by a variety of organizations including the National Park Service, Bureau of Land Management, and others.
As of 03/20/2020, there are 128 National Monuments in the United States1.
I would like to visit all of them, so this is a running list of the monuments I have visited and photographed.
Some of the items on this list will have links if I have written about my travels to them.
