Now, hikers have to add an additional mile of hiking before reaching the official TH.

Desert Peak (7,005 ft) is located in the Newfoundland Mountains in the Great Salt Lake, and is the highest point in the range. Getting to the unofficial trailhead takes quite a bit of effort, and it is very tricky timing it at just the right time of year. Because it's located in the middle of the Salt Flats, any recent precipitation will leave the dirt roads completely muddy and rutted out. There is zero cell service, so you don't want to risk getting stuck.
