Castle Rock Quarry BE0211 - 12/10/2002

Prev | Index For This Date | Next
Most leaves at Castle Rock are on the horizontal plane. However, we occasionally recover specimens that came to rest on the diagonal in a flood event. It seems to indicate that the flood events that preserved the Castle Rock rainforest were small but quick events. Each layer averages no more than 6 inches thick. Most leaves are found in leaf mat layers in a horizontal position. They are in between layers of mud deposition. However, we sometimes find very nice specimens in the middle of the flood event - in an extremely hard grey matrix material. One can just picture the leaf coming to rest in the dynamic sediments - washing up against an enbankment, a tree or some other obstacle - never to move again.
