This was all Jerry’s idea. He wanted to go out to the Beaver Dam Mountains and look at the cool metamorphic rocks. There is a canyon on the other side of the mountains, he said. Why don’t we go check it out? Now, Jerry is a geologist but he is also a paleontologist, one of those peculiar people who studies dead things in mud. He claims metamorphic petrology sets his head to spinning. I only have an undergraduate degree in geology but I completed three years worth of field research in these rocks and did my senior project on them (you can read about some of that here!). He figured I could help him recognize a few things and so I said I would do my best to enlighten him.
