Deeper Nature Study: Bacteria at Yellowstone

I know this is a field trip that won't happen for my small group of homeschooled bacteria hunters anytime soon, but we traveled to Yellowstone a few years ago with my own family, and have photos to prove it.  This was taken before our bacterial-hunting days, but it's a fine photo of hyperthermophilic bacterial (archea) growth patterns, demonstrating iron oxidation (rust colored sediment).
