Photo Gallery

Negit Island, capped by the dark-colored cinder cone at the right, was the source of one of the most recent eruptions of the Mono Lake volcanic field. Rhyodacitic lava flows overlie a 1240 CE tephra unit. The light-colored tufa deposits near the western shore of Mono Lake in the foreground were created by deposition of calcium carbonate beneath the waters of the lake.

Paoha Island in the center of Mono Lake at the left is seen from the flanks of Panum Crater on the south, at the northern end of the Mono Craters. The Mono Lake volcanic field consists of multiple volcanic vents on the northern shore of the lake and on Paoha and Negit Islands, which were last active a few hundred years ago.

The Mono Lake volcanic field consists of rhyolitic lava domes and flows, phreatic explosion craters, and cinder cones on islands in Mono Lake and on its northern shore. This view shows explosion craters on Paoha Island, with the Mono Craters dome complex and the Sierra Nevada in the distance to the south. The ages of the most recent eruptions of the Mono Lake volcanic field range from about 2000 to about 200 years.

Negit (right-center) and Paoha (far right) islands in Mono Lake are seen from Black Point, a basaltic cone on the NW shore of the lake. The most recent eruptive activity from the Mono Lakes volcanic field took place 100-230 years ago, when lake-bottom sediments forming much of Paoha Island were uplifted by intrusion of a rhyolitic cryptodome. Black Point is an initially sublacustral cone that formed about 13,300 years ago when the lake was higher. The White Mountains form the far right horizon.
