Mono-Inyo Craters in California, U.S.A., are a nearly straight line of small volcanoes that stretch from Mammoth Mountain and Long Valley Caldera in the south to Mono Lake in the north.
Mono Craters to the north sit along the eastern edge of Pumice Valley, a large caldera volcano.
Panum Crater is the northernmost volcano in the sequence and is a good example of both a tuff ring (a type of volcano created in a phreatic eruption) and a rhyolite dome.

Spanning from the ancient Mono Lake which still remains today, to a rather new chain of craters referred to as the Mono-Inyo Craters, the Mono Basin portrays the evolution of this area in a physical sense during very active and thus exciting times, including present day.
Because of the Mono Basin's lower elevation compared to the mountain borders, it might be hard to believe that this lake at one time was large enough to overflow its rim.

Volcanic eruptions are not as common as earthquakes in California, but, like earthquakes, they have played a significant role in shaping the landscape along the eastern Sierra Nevada range.
Scientists estimate that eruptions have occurred in the area for nearly four million years and that two volcanic systems - the Long Valley Caldera and the Mono-Inyo Craters volcanic chain - are responsible for most of the activity.
Mammoth Mountain, the Mono Craters and Inyo Craters also owe their existence to volcanic activity in the Mono-Inyo Volcanic Crater chain.
