  Mono Lake - Wikipedia, the free encyclopedia
Mono Lake is an alkaline and hypersaline lake in California, United States that is a critical nesting habitat for several bird species and is one of the most productive ecosystems in North America.
Mono Lake was spared the same fate on September 28, 1994, when the California State Water Resources Control Board issued an order to protect Mono Lake and its tributary streams.
Mono Lake is a vital resting and eating stop for migratory shorebirds and has been recognized as an International Reserve in the Western Hemisphere Reserve Network.

 Russell's Report on the Mono Craters   (Site not responding. Last check: 2007-10-08)
The craters that were points of eruption for lapilli and lava may again be divided into two classes: (1) Those in which the lava did not escape from the bowls formed by the eruption of lapilli, and (2) those that were the sources of the coulees.
The Mono Craters are grouped in a north and south line, and, from the nature of volcanic eruptions in general, we conclude that they were formed along a fissure, probably a branch of the great Sierra Nevada fault.
The majority of the craters immediately south of the hydrographic rim of the Mono basin and on a line with the Mono Craters are of a dark basaltic lava, very different from the erupted material forming the numerous cones to the northward.

 Storm over Mono: CHAPTER ONE
Chemically, Mono is known as a triple-water lake: it is saline; it is alkaline; and, due to its volcanic surroundings, it is sulfurous.
Mono Lake's population of several hundred birds is one of the largest in the state.
Mono water was too salty for them even then, and the lake too choppy when the wind blew, so they gathered in sheltered spots where the surface layer of water was fresher: near creek mouths, in coves, and on the brackish lagoons that bordered the northeast shore of the lake.

Mono Craters includes 3 large rhyolitic (obsidian) flows, 6 to 8 steep-sided rhyolite domes, a number of explosion craters, as well as the islands in Mono Lake, and Black Point, the basaltic lava flow on the north shore of the lake.
The Mono domes and flows are steep, blocky, and barren, reflecting their glassy texture and youthful age.
The arcuate shape of the Mono crater chain has lead scientists to suggest that the Mono Craters may be analogous to the Glass Mountain rhyolite and hence a precursor to caldera formation (the dashed line on the map to the left).

The Mono Craters comprise a young volcanic chain associated with the Long Valley caldera in eastern-central California.
Mono Craters are part of a larger structure that includes the Inyo Craters to the south and the volcanoes of Mono Lake to the north, which together form a 40-km-long chain of Late Pleistocene and Holocene craters, domes, and flows.
Mono Craters lie just south of Mono Lake, and can be easily viewed from the lake, as well as from Highways 395 and 120.

 Recent Changes in Mono Basin, California
It is a shallow depression surrounded by the Sierra Nevada on its west, volcanic uplands on its north and east, and a chain of young explosive volcanoes, the Mono Craters, on its south.
From the sedimentary record Mono Lake is estimated to be at least 730,000 years old, and therefore one of the oldest bodies of water in North America.
Almost all Mono Lake dust particles are of a size of about 11 m or smaller, and are therefore capable of causing irritation to the human respiratory tract.

Mono Lake, located in Mono County CA, is a closed lake system that experienced multiple transgressive-regressive cycles that have produced many noticeable lake terraces.
During the mid-Holocene, Mono Lake transgressed to form one of its highest terrace that is comparable to it previous counter part, viz.
Of particular interest is the deformation of the the mid-Holocene terrace by the intrusion of magma beneath the Mono Craters which occurred around the 14th century.

 Volcanoes of the Eastern Sierra Nevada
The Mono Crater chain that will be the focus of this paper is just outside the caldera and is a part of a larger structure that forms a 40km chain of craters, domes, and flows dated to the late Pleistocene and Holocene era4.
The Mono Craters are special because they are towards the end of the line in the Mono-Inyo Crater chain and exist as examples of very young volcanic activity.
The Mono Craters are well preserved and play a role in better understanding the formation, intrusion and movement of a magma body in relation to the extremely complicated tectonics of the Long Valley region.
