The Great Salt Lake is a mysterious place that few take the time to appreciate or study. It originally was Lake Bonneville. During the ice ages of Pleistocene Epoch, it stretched from Southern Idaho, through parts of Nevada and covering much of present-day Utah. At its deepest point, the lake averaged a depth of 923 feet submersing almost all of the Wasatch Front which is the home of over 2.4 million people. Today, the average depth of the Great Salt Lake is only 16 feet.
