Mount Laguna Observatory, Cleveland National Forest

Mount Laguna Observatory is an astronomical observatory owned and operated by San Diego State University. The telescope was operated in partnership with the University of Illinois at Urbana-Champaign until 2000. MLO is located approximately 75 kilometers east of downtown San Diego, California on the eastern edge of the Cleveland National Forest in the Laguna Mountains on the SDSU Astronomy Campus near the hamlet of Mount Laguna. MLO was dedicated on June 19, 1968, seven years after SDSU's Department of Astronomy became an independent academic department of SDSU's College of Sciences. The dedication took place during the 1968 summer meeting of the Astronomical Society of the Pacific. Currently SDSU is working with University of Kansas, and UNC Chapel Hill on various projects. ()
