Ben Reichardt and I spent three days hiking part of the John Muir Trail from Happy Isles in Yosemite Valley to Devil's Postpile. Ray and Serene joined us for the first day and headed back to the valley the next day. We covered about 14 miles the first day and gained 5000 feet to reach Sunrise High Sierra Camp. The second day, we covered about 22 miles and 1000 feet to camp below Donohue pass. The last day was also the most spectacular but unfortunately the light wasn't ideal for photography.
