When you see a bunch of tents, you are at Trail Camp. If you find yourself trudging up a series of 97 switchbacks, you are past it. It would be useful to get a map of the trail and look at the major landmarks: Lone Pine Lake, Bighorn Park, Outpost Camp, Mirror Lake, Trailside Meadows, Consultation Lake, Trail Camp, 97 switchbacks, Trail Crest, John Muir trail junction, the Summit.
