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.
