Roosevelt Reservation, Border protection zone in Arizona and New Mexico, United States.
The Roosevelt Reservation is a 60-foot-wide strip of federal land running along the US-Mexico border through California, Arizona, and New Mexico. This federal zone stretches for miles across the border region and is managed by federal agencies to control access and movement in the area.
President Theodore Roosevelt established this reservation in 1907 through Proclamation 758 to prevent smuggling activities between the two countries. The measure became part of a broader border security system designed to strengthen control over this critical region.
The reservation marks a physical boundary between two countries, shaping how border communities on both sides move through and experience their shared region.
Access to this federal zone requires prior authorization from the appropriate authorities. Visitors should research which areas are accessible and what documentation is needed before attempting to visit, as the zone is closely monitored.
Texas is excluded from this reservation because the state retained control of its public lands when joining the United States. This makes the reservation unique in its geographic reach and is often overlooked by visitors learning about the border.
