The John Muir Trail runs 212 miles along the crest of California's High Sierra, from Yosemite to Mt. Whitney. Did you know that its creator was the direct descendant of the only Jewish clergyman in attendance at George Washington's inauguration in 1789? Michael Hoberman tells the story of Theodore Seixas Solomons' 1890s explorations of the Sierra, as well as of his tireless (and largely unrecognized) contributions to the creation of the nation's most scenic high-elevation footpath.
