It's been a rough Summer in the high Sierras. I am in the planning stages of an attempt to hike the John Muir Trail from Yosemite. I need time to get my business to where it can run without me for a month in Summer, so I'm shorting for 2015. What will the weather be then? Will the streams be too high to ford? Will the passes be too snowy. Will thunderstorms come up every afternoon making hiking over 12,000' passes precarious. You picked a rough Summer, my fingers are crossed for July into August, 2015.
