The Tortugas Mountain Observatory is an astronomical observatory owned and operated by New Mexico State University.  It was built in 1963 to observe the planets.  Regular use of the observatory ceased around 1999 but the equipment was never dismantled.  In 2010 efforts were made to reestablish the observatory.  As of 2011 the work was still on-going.  The observatory is located on Tortugas Mountain near Las Cruces, New Mexico, USA.
