Looking at a map of this trail might cause a little bit of confusion considering the name, since the shoreline it follows is that of an ancient lake that covered most of what is now northwest Utah. Lake Bonneville, which was a freshwater lake, existed in its largest form around 14,500 years ago. Today, the Great Salt Lake is all that is left of the Pleistocene-era lake that was nearly the size of Lake Michigan. The trail that is being built along this long-ago shoreline is currently in segments totaling 100 miles, but there is a proposal to expand the trail into 280 continuous miles stretching south from the Idaho border to the town of Nephi, Utah.
