I haven't posted since early August. I've been very, very busy with the start of the fall semester and work always comes first. I do hope to at least start posting weekly again (and have several half-written posts waiting to go).
For now, here's a picture of me leading a group of geology students through a local cement mine during a field trip a couple of weeks ago.
I could write a book about these mines (if only I had the time...).
