As the largest natural lake west of the Mississippi River and the largest salt water lake in the western hemisphere, the Great Salt Lake is perhaps the best known geologic feature in the area. The city even takes its name from the lake - originally it was Great Salt Lake City, but the "Great" was dropped from the name in 1868. The lake has a rich history, interesting features, plays an important role in the ecosystem and provides abundant recreational opportunities.

Prehistoric origins

The Great Salt Lake is the remnant of Lake Bonneville, an enormous prehistoric lake that covered a large portion of western Utah. If you look around the Salt Lake Valley, you can see remnants of the shoreline of Lake Bonneville as terraces on the mountainsides. You can evenhike or bikealong that ancient shoreline if you follow the Bonneville Shoreline trail. The lake was well known to Native Americans, but was first seen by Europeans Jim Bridger and Etienne Provost in 1824. After the area was settled in 1847, some settlers (and later others) claimed to see what has become known as the North Shore Monster - the Great Salt Lake's version of the Loch Ness Monster.

Just the facts - depth, area and more

The lake is very shallow (current maximum depth is only 35 feet), so the area it covers varies depending on how much snow melt and runoff reaches the lake. During an average year the lake covers about 1,700 square miles. In 1963 the surface area reached a historic low at 950 square miles. Just 25 years later, in 1988, it reached a record high of 3,300 square miles. The large surface area of the lake and shallow depth contribute to area snowfall with "lake effect" snowstorms in winter and thunderstorms in summer generated by warm evaporating water meeting colder air as it reaches the nearby mountains.

Recreation in, and around, the lake

The lake and its islands offer residents and visitors opportunities to sail, kayak, float, birdwatch, hike, bike and more. At theGreat Salt Lake Marinayou can launch a kayak or boat, go on a sunset cruise, or take in the spectacular view. Nearby is the Saltair - a resort that has been rebuilt three times in its history, and is currently used as a concert venue. The best place to swim or float in the lake is atAntelope Island State Park, where white oolitic sand beaches provide easy access to the lake without the brine flies that are prevalent on other areas of the shoreline. The beach area also has showers to rinse off the salty water. Floating in the lake is a unique experience because the high salt content makes it easier to float.Antelope Island also has hiking and biking trails, spectacular views, and the historic Fielding Garr Ranch.If you visit near the end of October, check out the annual Bison Round-up where the free ranging bison on the island are gathered together on the north part of the island. If your visit happens during other parts of the year, be sure to check out theother events happening at Antelope Islandorthe Marina.

What about fishing?

It's a lake, so what about the fishing? There is some limited fishing available near the marina and the other fresh water inlets to the lake. Because the lake has no outlet and only loses water by evaporation most of the lake is too salty to support fish or other aquatic life larger than algae and brine shrimp-the larvae of brine flies. The lake has salinity that ranges from two to seven times as salty as the ocean. The salt and other minerals in the lake come from the minerals in the water from the ancient lakebed and the river water that flows into it. There are very small amounts of minerals in the water from the Weber, Jordan and Bear Rivers—the three major rivers that feed into it—but the water evaporates from the lake leaving the salt (and other minerals) behind.

Birdwatching at the lake

​There might not be fishing or other large aquatic creatures in the lake, but the lake is an essential part of the ecosystem because of the extensive wetlands that are along the shore of the lake and the brine flies and shrimp are essential food sources in those wetlands. TheGreat Salt Lake Shorelands Preserveis part of the wetlands of the Great Salt Lake. The preserve and other wetlands of the lake provide an essential stopping point in the migration of millions of migratory birds including: Wilson's phalarope, red-necked phalarope, American avocet, black-necked stilt, marbled godwit, Snowy Plover, western sandpiper, long-billed dowitcher, tundra swan, American white pelican, white-faced ibis, California gull, eared grebe, peregrine falcon, bald eagle, and various ducks and geese. This makes the area around the lake a great place to gobird watching. The Shorelands Preserve even has a handicapped accessible boardwalk that provides close up access to see the birds.

Arts & Culture

In addition to spectacular views of the surrounding mountains, the lake itself and the wildlife, the northwest arm of the Great Salt Lake is home to a land art installation work byRobert SmithsoncalledThe Spiral Jetty. Constructed in 1970, the land art is visible above the water as white salt encrusted rocks in a spiral formation. When the lake is high enough to cover the rocks, the installation is still visible from the air during ascenic flight.

FAQs

What is the history of the Great Salt Lake? ›

What we now know as the Great Salt Lake started as Lake Bonneville, a predominantly freshwater lake that formed about 32,000 years ago, and at its greatest extent, covered about 20,000 square miles — almost a quarter of present-day Utah.

What are 3 fun facts about the Great Salt Lake? ›

The Great Salt Lake boasts some of the world's largest populations of birds! The area is a regionally, nationally and hemispherically important ecosystem for migratory birds. No fish can survive in the North or South arms of the lake. The largest aquatic animals in the lake are brine shrimp and brine fly larvae!

Did people used to swim in the Great Salt Lake? ›

Utahns considered bathing in the Great Salt Lake as healthful long before Saltair opened. Travel guides in the 1870s compared the Great Salt Lake to the Dead Sea, touting it as a natural remedy for respiratory conditions, digestive disorders, and other chronic illnesses.

Who was the first person to see the Great Salt Lake? ›

The first white explorers whose accounts are fully credited were the trappers Étienne Provost and Jim Bridger, who came upon the lake independently in 1824–25.

Why is the Great Salt Lake famous? ›

Great Salt Lake is the largest saline lake in the Western Hemisphere and the eighth largest in the world. The ecology of the lake is an extraordinary example of the rich web of relationships between people, land, water, food and survival.

Was the Great Salt Lake once an ocean? ›

It was called Lake Bonneville, and northern Utah, southern Idaho, northern Nevada was all underwater, a freshwater lake. But as the Earth warmed up, ice dams broke, and water evaporated, and all the water seeping out left behind this salty puddle in the bottom of the bathtub, and that's what we call Great Salt Lake.

Why is the Great Salt Lake so gross? ›

The saltiest of the Great Salt Lake's water sits on the bottom of the lake. The heavy brine traps organic material (i.e., algae and plant and animal remains) and gases at the bottom of the lake.

What makes the Great Salt Lake smell bad? ›

The eighth largest saline lake in the world is a Utah icon. More than 10 million birds take sanctuary there every year. And sometimes, Great Salt Lake smells like rotten eggs. That distinct tang is caused by hydrogen sulfide, a colorless gas that can be harmful in high concentrations.

Is there any life in the Great Salt Lake? ›

The Great Salt Lake is home to many important biological and wildlife species, from archaea, to bacteria, to phytoplankton (400+ species). Perhaps the three most apparent species that can be seen with the naked eye are brine shrimp (tons), brine flies (billions) and birds (millions).

What is at the bottom of the Great Salt Lake? ›

The shallow bottom of Great Salt Lake supports a microbial carpet that harness the sun's energy through the process of photosynthesis. This carpet is made up of a community of microbes, including several types of cyanobacteria (also known as blue-green algae), algae and other organisms.

Were there ever whales in the Great Salt Lake? ›

According to the article, two juvenile Australian whales, one female and one male, were “planted” in Great Salt Lake in 1873. James Wickham imported them and commissioned special rail cars filled with seawater to transport the whales from San Francisco to the lake.

Does the Great Salt Lake freeze? ›

Even when the water temperature is in the 20's (°F), the lake does not freeze, due to the high salt content of the water; but icebergs have been ob- served floating on the lake's surface, formed from freshwater that flows into the lake from tributaries and freezes on the surface before it mixes with the brine.

What happened to the Great Salt Lake in the 1980s? ›

These images show the dramatic effects of the Great Salt Lake's high water levels in the 1980s. These effects included a great increase in the lake's area, the opening of the causeway crossing the lake, and the creation of a new evaporation basin west of the lake.

Why was the Great Salt Lake pink? ›

Halophiles are extreme salt-loving microorganisms that have a unique pigment, giving the water its peculiar pinkish color. The South Arm of the lake averages about 12–15% salinity, while the North Arm averages around 26–30% and contains halophiles with a purple to pink hue.

Why is the Great Salt Lake not a sea? ›

Water flows downhill, and the ocean is at the bottom of the hill, right? But Great Salt Lake sits at the bottom of a "closed basin". It's a terminal lake. The only way water can leave is through evaporation.

What caused the Great Salt Lake to be salty? ›

As rain water and snow melt run down the mountains, minerals and salts are eroded and eventually end up in the Great Salt Lake. Since the lake is a terminal lake, the only way water can leave is through evaporation, leaving the salt and minerals behind. Different parts of the lake are saltier than others.

How deep was the Great Salt Lake originally? ›

Why is the Great Salt Lake disappearing? ›

Utah officials have pushed the Great Salt Lake to the brink of an ecological collapse because they allowed upstream water to be diverted for decades to farmers growing alfalfa, hay and other crops, according to a lawsuit filed Wednesday by a coalition of environmental groups.
