It was one small group who blew the rock in the Salt River Canyon (HCN, 10/10/25). The guy who lit the fuse was too incompetent to get himself or his customers past an irreplaceable, completely natural challenge.
It broke my heart, even though my rafting is defined by the inner tube. No one has a right -- none at all -- to take such an action for safety, economic gain or because they're too gutless to face the challenge.
Nature has had the same attitude since the Big Bang and it's only our privilege, not our right, to face her machinations. If you can't get past that particular truism, please stay in the kiddie pool.
