The Gipsy-1 ({{lang-rus|Гипсы-1||ˈɡʲipsɨ ɐˈdʲin}}) is a system of 2680 m long interconnected adits in Kamsko-Ustyinsky District, Tatarstan, Russia, where gypsum was mined in 1930-1950s. It is the only mine in the area that can be visited by outdoor tourists, since other similar mines have been buried or flooded.[1] References1. ^http://speleo.ucoz.ru/faq/
