Are the Mono Inyo Craters active?
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.
Which volcano type is Mono Craters?
phreatic
Most of the Mono Craters, which make up the bulk of the northern part of the Mono–Inyo chain, are phreatic (steam explosion) volcanoes that have since been either plugged or over-topped by rhyolite domes and lava flows.
When did mono Inyo Craters last eruption?
about 270 years ago
The Mono–Inyo volcanic chain is a system of craters, domes, and lava flows that began erupting around forty thousand years ago [Alt and Hyndman, 2000], with the most recent eruption occurring about 270 years ago [Tierney, 2011].
What type of volcano is panum?

Is Mono Lake a volcano?
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.
Is Long Valley caldera still active?
Long Valley Caldera and the Mono-Inyo Craters chain form a large volcanic complex in eastern California that has had persistent earthquake activity and ground uplift in recent decades. Volcanoes have been active in the area for millions of years, and future eruptions are certain to occur.
Is Mono Lake a caldera?
Mono Lake is located north of the Long Valley Caldera, a 20-mile long depression that is the aftermath of a volcano that erupted 760,000 years ago. In a massive explosion the volcano sent huge volumes of earth and ash into the sky and buried the surrounding area in hundreds of feet of volcanic debris.
Is Mono Lake volcanic?
The Mono Lake volcanic field east of Yosemite National Park and north of the Mono Craters in central eastern California is a series of cinder cones in Mono Lake and on its shore. It is one of the most recently active volcanoes in California, the last eruptions having occurred at Paoha Island only 100 or 230 years ago.
Is Panum Crater extinct?
Overview. Panum Crater is a small, dormant, single crater to the north of the Mono Craters Chain in the Mono Basin of the Eastern Sierra Nevada, California, immediately south of Mono Lake and east of Highway 395. It lies within the Mono Basin National Scenic Area and can easily be reached from Highway 120.
Can you go swimming in Mono Lake?
A swim in Mono Lake is a memorable experience. The lake”s salty water is denser than ocean water, and provides a delightfully buoyant swim. Old timers claim that a soak in the lake will cure almost anything. Keep the water out of your eyes or any cuts, as it will sting.
Is Mono Lake toxic?
Mono Lake sits in a sealed basin close to California’s Yosemite National Park. With no outlet connecting it to other bodies of water, any chemicals flowing into the lake tend to stay there. As a result, the lake has built up some of the highest concentrations of arsenic on the planet.
Will the Long Valley Caldera erupt again?
The pattern of volcanic activity over the past 5,000 years suggests that the next eruption in the Long Valley area will most likely happen somewhere along the Mono-Inyo volcanic chain.
Is it safe to swim in Mono Lake?

What is the white stuff at Mono Lake?
The delicate white tufa towers along the shore of Mono Lake are calcareous (calcium carbonate) deposits formed where fresh-water springs percolate through lake-bottom sediments and saline lake water.
Is the Panum Crater dormant?
Panum Crater is a small, dormant, single crater to the north of the Mono Craters Chain in the Mono Basin of the Eastern Sierra Nevada, California, immediately south of Mono Lake and east of Highway 395.
Can obsidian be purple?
When tiny bubbles of gas are trapped in the rock and result in a reflection of purple color, a purple sheen obsidian happens. Sometimes, the two different colors exist in the same specimen of the obsidian rock.
