  Negit Island
The Negit Island volcanic complex is less than 2,000 years old.
But, if the lake falls to 6375 feet, a land bridge is formed to connect Negit Island to the northern shore line.
The formation of the land bridge eliminates Negit Island as a breeding ground that is safe from predators.

 Mono Lake
The level of the water went down so far that Negit island (dark colored island in picture - to be inserted later) became a peninsula which exposed the nests of gulls to coyotes.
The dark colored Negit island is of volcanic origin and is somewhat less than 2000 years old.
Pahoa Island is the larger and lighter colored island in the lake and was formed 300 years ago from uplift caused by magma movement.

 At Mono Lake Introduction   (Site not responding. Last check: 2007-09-05)
A fiery chapter in Mono's recent history began with the volcanic eruption of the Mono Craters and subsequent activity that formed Negit Island, Paoha Island and Black Point.
Throughout its history Negit Island has provided a home and safe breeding ground for 95% of the state's California gulls.
As a result a land bridge has formed to Negit Island, providing access for coyotes and other predators to prey on nesting gulls, and has destroyed this state-protected rookery.

The island is composed primarily of lake sediments.
The island is so valuable to birds because it provides them with a safe place secluded from humans, coyotes, and other mammals (Carle 15).
The islands are essential havens for the gulls’ nests, protecting the eggs and chicks from coyotes and other land predators (Carle 15).

 The Sierra Web | Mono Lake, California
After 1979, when the declining lake connected the main gull-nesting island to the shore, the media and the public focused attention on the plight of the gulls at Mono Lake.
Islands are of critical importance, where their nests can be safe from coyotes or other predators that might otherwise walk up and eat their eggs and chicks.
The scene on the islands is noisy and crowded.

Geomorphic Studies and Hazard Evaluation of Negit Island and Mammoth Mountain, Long Valley Caldera, California
Mammoth Mountain, a cumulovolcano emplaced during the Mammoth sequence (119-57 ka), and Negit Island, a small island in Mono Lake (generated during the Inyo sequence, 6 ka—present), are especially important because they represent the most recent volcanic activity in the region.
Geologic maps of both Mammoth and Negit will be compiled in order to provide an up-to-date snapshot of recent volcanic activity in the region.

 Mono Lake
Black Point is the remnant of a cinder cone volcano that erupted under water during on of the stands of Lake Russel.
In 1941 the city of Los Angeles extended an aquaduct system into the Mono Basin, diverting water that would otherwise have entered Mono Lake.
Enough water was diverted that evaporation soon exceeded inflow and the lake level fell rapidly, exposing alkaline sands and once-submerged tufa towers, and turning Negit Island into a peninsula, exposing the nests of gulls to coyotes.

Paoha Island is the large island in the middle of the lake created by uplift caused by the movement of magma.
The most recent eruptions in the area occurred from Negit Island (the small dark-colored island) in Mono Lake about 250 years ago.
To the south of Lake Mono in varying shades of purple, is the cluster of Mono Craters – the series of plug-dome volcanoes that make up the youngest volcanic chain in North America.

The youngest member of the Mono Basin volcanic family is Paoha, the white island in the middle of the lake, which formed only 300 years ago.
Paoha is, indeed, exposed lake-bottom sediment, pushed up over the surface of the lake in a volcanic upheaval that lacked the momentum to fully erupt.
Although there have been a few small lava flows on the north end of the island, Paoha has yet to let go in a full-scale eruption.

 Recent Changes in Mono Basin, California
The target lake level of 6392 feet, (which is still 25 feet below its pre-diversion elevation) is thought to incorporate an adequate buffer to protect the brine shrimp and other components of the ecosystem from extreme salinity during prolonged drought.
The islands will be surrounded by plenty of protective water, and the dust storms should be reduced to acceptable levels.
On the images, the growing of the islands and the appearance of a landbridge in the late 80 s is clearly visible.

 Mono Lake Summary
The lake's islands provide safe nesting for tens of thousands of California gulls and snowy plovers.
Nearly 90% of the state's population of California gulls, which live mainly along the Pacific coast, are hatched on these islands.
As the water level dropped, the lake's salinity increased and shoreline habitat for brine flies decreased.

The most publicized part of the issue was the threat to the breeding colonies of California Gulls on Negit Island.
As more and more water was diverted from the lake, a land bridge appeared between the island and the mainland, permitting predators to gain access to the gull colonies.
Furthermore, it was suspected that a continued lowering of the water would jeopardize the food resources of the lake, consisting of billions of tiny brine shrimp and alkali flies.
