Bristol Bay is the portion of the Bering Sea between the Alaska Peninsula and Cape Newenham on mainland Southwest Alaska. The Bering Sea ecosystem includes resources within the jurisdiction of the United States and Russia, as well as international waters in the middle of the sea (known as the "Donut Hole" [8]). The interaction between currents ...
California's geography is largely defined by its central feature—the Central Valley, a huge, fertile valley between the coastal mountain ranges and the Sierra Nevada. The northern part of the Central Valley is called the Sacramento Valley , after its main river, and the southern part is called the San Joaquin Valley / ˌ s æ n w ɑː ˈ k ...

The sea which is normally repleted by contact and inflow from the ocean is now no longer replenished and hence dries up over a period of time, which can be very short if the local climate is arid. In this scenario, rivers that previously flowed into the sea at a sea level elevation now can cut far deeper into the bottom of the bed now exposed.
It spans nearly all of Nevada, much of Utah, and portions of California, Idaho, Oregon, Wyoming, and Baja California. It is noted for both its arid climate and the basin and range topography that varies from the North American low point at Badwater Basin in Death Valley to the highest point of the contiguous United States , less than 100 miles ...
The Franciscan Group of California is interpreted as an ancient accretionary prism in which underplating is recorded as tectonic mélanges and duplex structures.
