2011 Wapama Falls rock fall
Fresh rock debris at the base of a rock wall and impact marks on the wall.
A rock fall approximately 1 km east of Wapama Falls at the three switchbacks connecting a lower bench with a higher bench. The rock fall source area was above the bench trail in an overhanging, already-weathered roof area with a tree nearby. The rock fall detached, impacted the cliffs near the base. This debris cut through the middle of all three switchbacks on the trail, with boulders coming to rest above, on, and below the trail.
