POTD: Making Fossils #1

Making Fossils #1 Yellowstone National Park, Wyoming 2013

Although there is snow on the ground, these trees aren’t drowning in it; rather they are buried in and were killed by the spreading travertine deposits from Canary Springs on the Mammoth Hot Springs Terrace. Travertine is made of limestone and many fossils form in limestone, so it seems like there should be some major tree fossils hidden at Mammoth. But I’ve only seen micro-organism fossils mentioned in discussions of the terrace geology.]]>
