Mono Lake Volcanic Field

Quick Facts

The Mono Lake volcanic field, east of Yosemite National Park and north of the Mono Craters, consists of vents within Mono Lake and on its north shore. The most topographically prominent feature, Black Point, is an initially sublacustral (below lake level) basaltic cone that rises above the northwest shore and was formed about 13,300 years ago when Mono Lake was higher. Lava domes and flows form Negit and parts of Paoha islands within Mono Lake. The most recent eruptive activity in the Long Valley to Mono Lake region took place about 300 years ago, when lake-bottom sediments forming much of Paoha Island were uplifted by intrusion of a rhyolitic cryptodome. Spectacular tufa towers line the shores of Mono Lake.
