Hi all! I've been away from the site for a bit - I taught my first historical geology lecture this spring, and ended up spending three nights a week working on a lecture til the wee hours of the morning, and so the last month has left me without enough time to follow up on the forum. I'll try to get caught up over the next few days. I have a bazillion missed messages from people, so I'll get through them ASAP!
This weekend I wrote a new (and very long) blog post about the geology, paleontology, and history of the Ashley Phosphate Beds in the Charleston area - a must read for anyone confused about our stratigraphy!
