Cave of the Bells is located in Sawmill Canyon on the eastern slopes of the Santa Rita Mountains of Santa Cruz County, Arizona. The cave contains a lake which is 80 meters below the entrance level.

The Sahuarita Air Force Range, also known as the Sahuarita Bombing & Gunnery Range, was built just east of Sahuarita, Arizona, in 1942. It was used for the training of bombardiers, aerial gunners, anti-aircraft gunners, and others during World War II and the Korean War. The abandoned Sahuarita Flight Strip (31°57′50″N 110°55′29″W) is located in the southwestern corner of the range, and was used as an emergency flight strip until 1978. Before deactivation, the airspace over the range was protected by its own restricted area, R-310.

The Infrared Optical Telescope Array (IOTA) was a stellar interferometer array. IOTA began with an agreement in 1988 among five Institutions, the Smithsonian Astrophysical Observatory, Harvard University, the University of Massachusetts Amherst, the University of Wyoming, and MIT/Lincoln Laboratory, to build a two-telescope stellar interferometer for the purpose of making fundamental astrophysical observations, and also as a prototype instrument on which they could perfect techniques which could later lead to the development of a larger, more powerful array. On site construction went on for all 1993 and 1994, with first fringes in December 1993. It is located at Fred Lawrence Whipple Observatory. In 2000 the third telescope came online providing closure phase observations, allowing aperture synthesis imaging to be performed for the first time at IOTA. The array was decommissioned and disassembled in summer 2006 due to lack of funding.
