Imagine strolling through Yosemite Valley some 140 years ago with naturalist John Muir listening to his poetic descriptions of Half Dome and learning about his legendary adventures. As one of Yosemite Conservancy’s unique Outdoor Adventures in 2012, visitors to Yosemite National Park can take a step back in time by retracing Muir’s steps with his great-great-grandson Robert Hanna and Muir actor Frank Helling. The four-mile hike this April will explore where Muir lived and worked in Yosemite Valley, and his favorite spots and discoveries. https://www.nps.gov/yose/learn/news/ycjohnmuiradventure.htm
