I need to make it crystal clear that none of this is my own research. The pictures on this and associated pages were taken on a GSA field trip in 1994 led by Richard B. Waitt of the U.S. Geological Survey, and the interpretations presented here are largely those of Dr. Waitt as presented on the field trip and its guidebook. I thank Dr. Waitt and his colleagues for a stupendous field experience.
