Grind up from Guardsman Pass Road, passing the top of the Park City's Jupiter lift, and then out a ridge with amazing views both north and south. At the end, you can walk up to the very top of Jupiter Peak at 9,998'. I suggest you build a 2' cairn.
The surface is mostly small to medium sized loose rocks and not particularly nice, but this is a good way to connect some amazing trails like Scott's Bypass
, Dead Tree Trail
, and Apex Trail
