The Mono Craters, lying on the eastern side of the Sierra Nevada between Mono Lake and Long Valley caldera, form an arcuate, 17-km-long group of 30 or more dominantly rhyolitic lava domes, lava flows, and tephra rings. The partially overlapping dike-fed domes were erupted near the margin of a pull-apart basin on the east side of the Sierra Nevada. Explosive eruptions began more than 50,000 years ago from now-buried vents, but almost all of the exposed domes and flows are of Holocene age. Activity has propagated both north and south from the center of the chain during the late Holocene. The latest eruptions occurred about 600 years ago, nearly contemporaneously with the eruptions from Inyo Craters to the south, producing a series of tephra rings and obsidian lava domes and flows at the northern end of the chain accompanied by eruption of locally extensive tephra layers.

The Mono Craters volcanic field, between Mono Lake in the foreground and Long Valley caldera at the upper left, is a 17-km-long chain of rhyolitic lava domes and thick, viscous lava flows. Mono Craters have been frequently active during the Holocene. Panum crater (the vent nearest to Mono Lake), is partially filled by a lava dome and was the site of the latest eruption from Mono Craters, about 600 years ago.

The hackly surfaced Panum lava dome, filling a tephra ring at the northern end of the Mono Craters chain, was one of five rhyolitic lava domes and flows emplaced at the end of a major eruption about 600 years ago. The eruption, which began with powerful plinian explosive eruptions accompanied by pyroclastic flows and surges, occurred just a year or two prior to another major eruption at Inyo Craters to the south.

Flow-banded rhyolitic obsidian of the Panum Crater lava dome was erupted about 600 years ago at the northern end of the Mono Craters. The greenish-yellow areas are lichens on the surface of the dome.

The Mono Craters volcanic field south of Mono Lake at the upper left, is a 17-km-long arcuate chain of rhyolitic lava domes and thick, viscous lava flows. Mono Craters has been frequently active throughout the Holocene, along with the Inyo Craters chain to the south. The Inyo Craters chain, which includes the Wilson Butte, Obsidian and Glass Creek domes, which are oriented diagonally along a N-S line from the left center to lower right of the photo. The latest eruptions of Mono Craters and Inyo Craters occurred nearly simultaneously around 600 years ago.

The Mono Craters volcanic field, seen here from the NW, is a 17-km-long arcuate chain of lava domes, lava flows, and tephra rings. The latest eruptions took place about 600 years ago from several vents at the northern end of the chain, producing rhyolitic lava domes and flows.
