My son Dylan and I were starting a five-day hike in the Cathedral Range near Tuolumne Meadows. Cathedral Peak is an icon among climbers, and one first "must-see" locations of the John Muir Trail. It is an enjoyable classic 5.6 alpine climb with a spectacular view from the summit of the entire Tuolumne Meadows area. I have climbed it countless times. Four times before this, I photographed here with mediocre results. This time, there was a wild lightning storm in the afternoon. The clouds cleared just at sunset. For once, I was all set up and ready when the alpenglow appeared. I vividly remember Dylan saying: "Don't do a mess up, Dad." At age 6, he was already translating a successful photo into trips to the local department store to buy toys.
