What are the most dangerous aspects of the John Muir Trail? A hiker uses data to discover
When John Ladd began surveying long-distance hikers on the John Muir Trail in 2012, he hoped to fill a void of critical information about the trail’s most dangerous elements.
He had recently become chief moderator of the Yahoo hub where thousands of hikers gather to swap stories and tips on how to tackle the famous trail, which stretches 221 miles through the High Sierra between the Valley of Yosemite and Mount Whitney. Backpackers find themselves caught up in dangerous situations on the trail each season – swept away by stream crossings, blighted by snowfields, and endlessly harassed by mosquitoes.
