there is also a good dayhike to the top of mount starr from the north. Start at the hilton lakes trailhead just above Rock Creek Lake and climb up the bowl to the top of Half Moon pass. After descending over a short class 3 section of the pass on the other side, go south and climb back up to the top of the ridge via a small saddle on the very northern end of Mt. Starr (easy class 2). follow the ridge south to the summit and exit via the mono pass trail back down to Rock Creek. This route makes a great dayhike for those who want to hike a cross country loop.
The summit is a long ridge running north-south with several summit blocks of similar height. While the northern ones seems to be the highest, the southernmost one is where the register is located.
