The Incredible Geology of Pluto

Back when I was a kid, I had no idea we'd ever be doing geology at the ends of the solar system. If I'd known then I could combine my love of astronomy with my passion for geology, I might even have abandoned my dreams of fiction writing and poured myself into a degree in the planetary sciences. Now we have robots in space, doing actual geology on other worlds. We've seen what the rovers on Mars have been up to. Now we'll turn to distant Pluto, which recently got downgraded to dwarf planet status. But just because a world is small doesn't mean it can't have world-class geology, and the things we're finding on Pluto are truly phenomenal.
