How best to spend one's Yosemite time, as accounted by John Muir in 1912, and retraced in 2013. Naturalist John Muir, in his 1912 book "The Yosemite", prescribes in Chapter 12 "How Best to Spend One's Yosemite Time". Turn for turn he drafts a one-day, two-day, and three-day excursion for best experiencing Yosemite, at a time when the park's borders were very much still in their infancy.
