Interestingly when I set up this page I relied on my GPS, and USGS topo software. Both these units record the summit of Perkins Peak at 40.44547 N, 111.46387 W. However, when trying to get the peaks to jive up with the map provided by SP, the peaks were way off. The coordinates on the page, 40.74485 N, 111.76366 put the tag directly over the summit on the SP map. Please use you own discretion with these GPS readings if using them to venture out to the peak.
