To help make sense of the geology, the best source I can find on line is this
and also this series of diagrams illustrating the geological history by the same author, Dr. Stefan Lang
which include links to some more photos. From a research home page for Dr. Lang, it seems he was studying the geology here between 1996 & 2001
Here are my photos as a NextGen gallery of reduced images for easier loading. Originals available.
