The Eastern California Museum was founded in 1928, and has been operated by the County of Inyo since 1968. The mission of the Museum is to collect, preserve, and interpret objects and information related to the cultural and natural history of Inyo County and the Eastern Sierra, from Death Valley to Mono Lake. The Museum collection is held in public trust, and a computerized database with over 15,550 records is used to manage the Museum's extensive collections. In addition to those artifacts, the Museum also houses about 27,000 historic photographs of the Eastern Sierra region, the majority of which date from the late 1800s through the 1950s. The Museum is also an outstanding resource for researchers, and typically handles about 200 requests for information or photo reprints per year.
