Monument Closures for Missile Tests
Due to missile testing on the adjacent White Sands Missile Range, it is occasionally necessary for visitor safety to close the road into the monument for periods of up to three hours. U.S. Highway 70 between Alamogordo and Las Cruces is also closed during times of missile testing. Visitors on a tight schedule are encouraged to call the monument at 575-479-6124 ext. 236 the day before arrival to confirm hours of operation.
