Nearby is the Magna Kennecott Smelter with its huge tailings pond visible easily in this satellite image. Look also at this topographic map of the Saltair / Magna area west of Salt Lake City. |
In the surrounding mountains there are also many active and abandoned mines including famous Ghost Towns that trace man's history of minerals extraction in the region. See for instance:
Ophir Ghost Town |
Mercur |

Mining companies have also extracted important evaporite resources from the lake. Pictured here is the pump and pipeline of the Great Salt Lake Minerals Corporation which brings saline water over the Behrens Trench to its evaporation ponds. You can also study more about salt production at the Salt Industry page. |
Brine-shrimp fishing has also become a major extractive
economic activity that is generating controversy and concern. In fact,
the industry has gone through a recent boom that resembles a type
of resource rush. This activity is of concern to biologist who
wonder whether the carrying capacity of the Great Salt Lake is
being threatened. Most of the shrimp ends up as an export to
Japan where it is used for commercial purposes.
Learn more from the Great Salt Lake Project at Westminster College of Salt Lake City. See some of th materials by Ty Harrison a biological ecologist and his students such as the Great Salt Lake Playa Foodweb Project. Read also about brine-shrimp ecology at the USGS site as well as Planktonic and Benthic Ecology of the Great Salt Lake.
Modern industrial and military activities of several types have come to impact the region besides the traditional salt extraction and mining. Recent economic activities such as power generation, brine shrimp fishing, and military weapons testing including the Toole / Dugway Chemical Weapons Incinerator has generated considerable local debate and even protest.
Its siting has caused some concern. It is located within a zone that is the last region in the lower 48 states with almost perfect visibility--often over a 100 miles. Unfortunately, this powerplant and others projected to come will decrease that pristine visibility.
This site along with many others across southern Utah have
become heavily embroiled in the much larger national and statewide
debate about how much land in Utah should be declared as
wilderness. See some of the websites listed below which
explore the pro's and con's of this major land debate focused on the
value of open space and wilderness. In summary, the Greater Salt
Lake Ecosystem Region, which many assume to be barren, desolate and even
dead ,is being threatened in several ways and is increasingly the focus
of controversy. This type of debate is growing around the
Inter-American West.
Quite early the Great Salt Lake became an oddity to be visited by tourists. One of the favorite places to visit was around famous Saltair Pavilion (see below):

The famous Saltair Pavilion and surrounding tourist facilities was flooded (1983-84) by the rising waters of the Great Salt Lake. During the Roaring 20's (see historical images) and in the early post-World War II era Saltair's large dance floor hosted some of the era's greatest Big Bands. Today it often hosts major Rock-Concerts. |

Modern recreational boaters also use the lake extensively--see the Great Salt Lake Yacht Club site. As the yacht club declares--it is home to the world's saltiest sailors! |
The Bonneville Salt Flats are world-famous as the site
where the land-speed record has been broken several times!

Some of the most recent land-speed record events, in fact, chose to do attempt their feat in the Black Rock Desert in Nevada partially because of this growing problem. |
In
sum, many types of people have come to the Great Salt Lake in search of
fun, adventure and profit--some even to break the world land
speed-record. The debates, public and private, about the lakes
importance or uniquesness and how to manage and preserve it continue
unabated. See some of the issues as described by the Friends of the Great Salt
Lake group.
The lake remained a formidable barrier to western expansion for a long time. The most famous group to be literally stuck in the mud flats and thus delayed in getting across the Sierra Nevada mountains was the tragic Donner party of 1846.

The Bonneville Salt Flats and the Great Salt Lake were also a significant barrier for the Pony Express (History). Part of that famous route still exists and crosses some of the most desolate parts of the West Desert (see Utah Pony Express Trail). |
In 1902 the Southern Pacific Railroad built its Lucin Cutoff across the lake from Ogden to Lucin. Tis shaved-off over seven hours of travel time. Building this required over 28,000 wooden piles to be driven into the soft lake bottom to support the trestle. Huge amounts of gravel and rock fill were also used eventually creating a permanent dike that has blocked off much of the northeast arm of the lake.

Railroad-builders from the past and even today have labored intensely to build causeways across this formidable barrier. The photo above shows the newest causeway across the southern end of the lake near Magna. |

What remains of the old wooden trestle that once crossed the lake from north of Ogden to Promontory Point? |

As mentioned earlier, Antelope Island (see State Parks page) has become the focus of a land use controversy regarding plans to build a causeway direct from Salt Lake City to the southern tip of the island (see the Antelope Island Draft Access Management Plan - 2004 (PDF) ). That is but one evidence of growing pressure on open land resources that continues--even in this supposedly protected state park. How the resources are managed--in this case for tourism--will also impact the island significantly. Debates are also increasing over management of the adjacent canyons, e.g. Little and Big Cottonwood Canyons.
The most recent controversy is just developing over the adviseability--or not--of building a new freeway system called the Legacy Highway. This major transportation corridor would cut through many of the most fragile wetlands along the lake's east side. Some of the issues involved are discussed by the Friends of the Great Salt Lake.
In addition, plans for a major expansion of the Salt Lake International Airport--now one of the nation's busiest--is also causing serious debate. The airport would also have to expand into sensitive wetlands near the mouth of the Jordan River.
I hope you have enjoyed your tour! Keep tuned to this site. Our goal is to continually add information and photos that update trends on Antelope Island as well as in the Great Salt Lake Ecosystem region at large. Thanks for coming and do give us your evaluation of this virtual tour and suggestions on improvement.
