This trailhead from June Lake is extremely steep and strenuous, and is recommended for folk that have extensive peak bagging experience, and endurance. Permit for 4 more. The first day is 12-14 miler from Rush Creek Trailhead, to Thousand Island Lake and then south along it to Lake Ediza. Approximately 3000 feet of climbing. We will camp at the base of Mt. Banner and Mt. Ritter. The second day will be climbing these peaks. The approach to the saddle will require crampons and ice ax, the rest is a tallus slog. Third day, easy day hiking out.
