John Muir Trail 2019 - Week 1


Week 1: Mammoth to Bishop Pass

The trek begins with a ride on a free shuttle from the village at Mammoth Lakes up to Horseshoe Lake and the Mammoth Pass trailhead. Dead trees surround the first mile of trail. According to a volunteer I spoke with soon after leaving the trailhead, this area suffers from very high concentrations of CO2. Not wanting to linger in a potentially poisonous atmosphere, I continued up the trail, reaching the first of the innumerable lakes to come.
