I'm wondering from the photos if the bush didn't just fly into the void taking all the dirt with it in its roots as the newly exposed rock looks remarkably clean. Could have happened during heavy rain with the extra weight of water. Something similar happened to the large tree at the first belay of Debutante in 1984. That was snow, but the principle is the same. The roots just take all of the dirt with it, and leave clean(ish) rock. |
