Yosemite's "Leave No Trace" certification requires removable gear like hexes instead of pitons. Routes now get two ratings - difficulty and environmental impact. The shift changed climbing culture; 78% of new ascents in 2023 used clean techniques. Some purists grumble about "nanny state" rules, but parks report 60% less visual scarring. The compromise? Historic piton routes remain but new developments must be reversible. Brands like Black Diamond now design gear specifically for low-impact climbing.
