Published June 18, 2026 04:07AM Editor’s note: On Friday, June 5, Yosemite guidebook author Erik Sloan re-ignited a fierce debate by adding more than a dozen bolts to Snake Dike (5.7 R; 800ft), a 1965 classic route on Half Dome that’s known for its sparse protection. Since then, some of the new bolts have been removed. When I think about the retro-bolting of Snake Dike, I think about surfing. YouTube videos of big wave surfing now routinely get millions of hits.
