Our virtual trip begins at the visitor center. The center is built with local stone called "phyllite." This photo shows an "augen," (German for "eye"), which is a larger piece of rock embedded in sediment before it underwent the change from sedimentary to metamorphic rock. These "eyes" are believed to have originally come from undersea landslides.
Close at hand to the visitor center are rocks that appear to have come form a river or stream bed, but this is the highest location around. How did this occur?
Some of these rocks contain fossils. The horizontal lines in this rock are fossilized worm cases. Even though this spot is now hundreds of feet above river level, we can thus tell that it was once under water.
