Hi Guys! I'm planning a trip to CA in September, and will be doing a section near Mammoth Lakes. We'll be starting at the PCT (High Trail) trailhead at Agnew Meadows and traveling north towards Thousand Island Lake. We'll be arriving mid-day, and was hoping to find a campsite a few miles in. A few resources show a campsite a few miles from the trailhead, near an overlook, which seems to be about 5 miles from Thousand Island Lake, and other sources do not show any camping areas. Just wanted to get some clarification of this area. Also, what type of elevation gain will I be reaching before things level off. I know Agnew Meadows is at 8400,, so wondering what type of climb I have. Thanks!
