Great Salt Lake

Way out west in the United States, in a state called Utah, you'll find the Great Salt Lake. It's like a huge, watery playground that doesn't have an end! It's so big that it can change its size, sometimes getting much larger and sometimes shrinking.

It's the biggest saltwater lake in the whole Western Hemisphere, which is a super long way to say it's the largest of its kind in a huge part of the world!

This lake is called the Great Salt Lake because it's super, super salty. It's much saltier than the ocean you might have visited! The water has lots of minerals, like salt, that get left behind because the water can't flow out anywhere.

When the sun heats the lake, the water evaporates and goes up into the sky, but the salt stays behind. This makes swimming there a funny experience – you float like a balloon!

Even though it's salty, the Great Salt Lake is a busy place for animals. Millions of birds come here to eat tiny brine shrimp and other yummy things in the water. It's like a giant rest stop and restaurant for them on their long journeys. You can see shorebirds and water birds all over the place. It's one of the most important places for these birds in the whole world!

This giant lake is actually a leftover from an even bigger lake that existed a super long time ago, called Lake Bonneville. Imagine a lake so big it covered a huge part of Utah! The Great Salt Lake is like a tiny piece of that ancient giant. It's a special place that tells us stories about what Utah was like thousands of years ago.
