I'm winding up the month with a couple of new posts about unusual topics. First is an appreciation of those ubiquitous roadside attractions "Rock Shops: What Are They Good For?" I think they're good for a lot, and while I no longer care personally about the run-of-the-mill specimens every shop has, I still find pleasure in poking around them and talking to the owners.
The second is about something I've been mulling for quite a while: what's the difference between geology and Earth science? I think that I'm probably just an old fogy, caught in a long transition between an old term and a new one that should mean exactly the same thing but at the moment have different connotations.
