Muir was my first 14er in 1988. It was just a 30-minute detour on the way to my first Whitney summit. The last time I was there was April 2013. I had just done the MR with Happy Trails and NYker. They waited on the Whitney summit while I scurried down to Muir and back. That was a two-hour round trip, with 30 minutes from the trail to the summit and back to the trail.
