Valentine Eastern Sierra Reserves (VESR) consist of two separate reserves, Valentine Camp and the Sierra Nevada Aquatic Research Laboratory (SNARL), located approximately eight miles apart. They are situated in Mono County on the eastern slope of the Sierra Nevada, near the Town of Mammoth Lakes, CA. VESR became part of the University of California Natural Reserve System (UCNRS) in 1973 and is administered through the University of California, Santa Barbara (UCSB). VESR provides protected wildlands, on-site experimental facilities, as well as the support facilities for conducting studies of natural systems over a large part of central, eastern California and western Nevada. The Reserve is open, by application, to any bona fide researcher or instructor. We welcome your interest and your inquiries.
