Great Salt Lake, Utah

The great Salt Lake, located in the northern part of the U.S. State that Utah, is the largest salt water lake in the west Hemisphere, and also the eighth-largest terminal lake in the world. In an mean year the lake consists an area of about 4,400 km2, however the lake"s dimension fluctuates substantially due to its shallowness. Because that instance, in 1963 it got to its lowest videotaped size in ~ 2,460 km2, yet in 1988 the surface ar area to be at the historic high of 8,500 km2. In terms of surface area, the is the largest lake in the United says that is not part of the great Lakes region.

The lake is the biggest remnant of Lake Bonneville, a prehistoric pluvial lake that once covered much of west Utah. The three significant tributaries come the lake, the Jordan, Weber, and Bear rivers together deposit approximately 1.1 million tons of mineral in the lake each year. As it is endorheic (has no outlet as well as evaporation), the has an extremely high salinity, much saltier 보다 seawater, which renders swimming similar to floating, and also its mineral contents is steadily increasing. Its shallow, warm waters cause frequent, sometimes heavy lake-effect snows from late autumn through spring. Back it has actually been dubbed "America"s Dead Sea", the lake gives habitat because that millions of indigenous birds, brine shrimp, shorebirds, and also waterfowl, including the largest staging populace of Wilson"s phalarope in the world. The great Salt Lake lends its name to Salt Lake City, originally named "Great Salt Lake City" through the president of The Church that Jesus Christ the Latter-day Saints (LDS Church) Brigham Young, who led a team of Mormon pioneers come the Salt Lake sink southeast the the lake ~ above 24 July 1847. The lake lies in parts of five counties: crate Elder, Davis, Tooele, Weber, and also Salt Lake. Salt Lake City and also its suburbs are located to the southeast and also east of the lake, in between the lake and the Wasatch Mountains, but land about the north and west shores are virtually uninhabited. The Bonneville Salt Flats space to the west, and the Oquirrh and Stansbury hills rise come the south.

Great Salt Lake is fed by three significant rivers and several boy streams. The three major rivers are each fed directly or indirectly from the Uinta Mountain variety in northeastern Utah. The Bear river starts on the north slope that the Uintas and flows north past Bear Lake, right into which several of Bear River"s waters have been sail via a fabricated canal right into the lake, yet later empty ago into the flow by means of the bear Lake Outlet. The river then turns southern in southerly Idaho and also eventually flows into the northeast arm of the great Salt Lake. The Weber River also starts top top the phibìc slope that the Uinta Mountains and flows right into the east edge the the lake. The Jordan flow does not obtain its water straight from the Uintas, quite it flows from freshwater Utah Lake, which itself is fed primarily by the Provo River; the Provo flow does originate in the Uintas, a couple of miles indigenous the Weber and also Bear. The Jordan flows from the north part of Utah Lake into the southeast edge of the an excellent Salt Lake.

We continue our tour roughly the human being in 2017 and also today we stop over the great Salt Lake. The lake is irregular in shape and is around 121km long from north to south and also 48 to 80km wide. The average depth the the lake is about 6m, but good seasonal sports occur. The lake is deepest in the spring, once it is fed by the melting eye from the surrounding Wasatch mountains to the east. Great Salt Lake occupies a section of what was, in Pleistocene times, the bed of the good Bonneville Lake. The existing lake has no outlets and loses water naturally only by evaporation, which concentrates the liquified salts brought into the lake through its tributaries and also causes its salinity. The salinity of an excellent Salt Lake, normally about 23 parts per 1,000, decreases once its area increases. The chief ingredient of the dissolved salts is salt chloride, which is recovered in advertisement quantities. The lake has been approximated to contain more than 5 million tonnes of salt chloride in solution. A few species of maritime life have actually been found, consisting of a brine shrimp variety.

In this latest Landsat comparison we aim to present in a time home window of 17 year (before - after) just how the great Salt Lake has actually changed. In these Landsat 7 and also 8 images, in fact, the lake is complete in June 2000 and in a dryness in may 2017, an especially in the area the the promontory peninsula.
