We're hitting the open road — geologically speaking. This episode kicks off our new state-by-state series covering the most fascinating, scenic, or just plain weird geologic stops in the U.S. We’re going alphabetically (because of course we are), starting with Alabama, Alaska, and Arkansas. Some sites we've visited, others are firmly on our dream list, but every pick is guaranteed to bring a bit of science to your next adventure.
