The massive lake would have wind-driven waves that would crash onto the tuff ring, eroding the rocks. This created a wave-cut platform. You can see the two folks from our group on that platform. The holes in the rock are from wave erosion as well. Eventually, the waves weakened the rocks on this side of the ring, and the walls collapsed.
