Mount Robie. One and one-half miles north of Ranger Peak is a flat topped summit (10,850 feet), the east ridge of which was climbed from Jackson Lake June 23, 1957 by Leigh and Irene Ortenburger. A cairn but no record was found. A difficult unexpected tower blocked an otherwise easy ridge. We rappelled to by-pass the tower on the south and then climbed it through a notch which separated it from the mountain. The long ridge was then traversed to Ranger Peak. On June 24 we also made the first ascent of a small sedimentary peak, immediately west of Ranger Peak, by its rotten east ridge.
