Protected areas

Organ Mountains–Desert Peaks protects many archaeological and cultural sites of interest. Before the Gadsden Purchase of 1853, this land included the border between Mexico and the United States. The Aden Lava Flow Wilderness Study Area is here and there are 243 known archaeological sites within the monument, including some of the earliest Native American settlements and petroglyphs known from three different tribes. The land also includes Shelter Cave and Conkling Cavern. Fossils of ground sloths have been found in the area.
More recently the land was used by William H. Bonney, better known as the outlaw Billy the Kid, and Geronimo, a leader during the Apache Wars, both of whom lived in various parts of New Mexico in the 19th century. It is said that Billy the Kid visited "Outlaw Rock", and there is a cave known as "Geronimo's Rock". The monument also includes of the historic Butterfield Stagecoach Trail.
The monument includes sites where World War II bombers practiced their targeting, as well as Kilbourne Hole in the Potrillo volcanic field, where American astronauts trained for lunar missions in the 1960s.

Campaign for establishment

The area was given national monument status following a campaign by conservation advocates that lasted several years. Several bills were introduced in Congress to protect the area through legislation, but they were blocked by House Republicans. In contrast with some previous monument designations, communities and governments of Doña Ana County were supportive of the application for designation. A poll found that 60 percent of the local voters favored establishing this land as a 500,000-acre national monument.
