In 2006, that smaller slide left a loosely-packed mass of debris perched dangerously above the Steelhead Haven development and its neighbors.</p><p> Tue, 22 Jul 2014 23:34:30 +0000 Gabriel Spitzer 17839 at http://kplu.org Scientists Say Smaller 2006 Landslide Set The Stage For Oso Disaster The oldest rock in the world tells us a story http://kplu.org/post/oldest-rock-world-tells-us-story It's hard to imagine how this teeny little rock — it's not even a whole rock, it's just a grain, a miniscule droplet of mineral barely the thickness of a human hair — could rewrite the history of our planet. But that's what seems to be happening.<p>What is this? It's a zircon, from the Persian word "zargun" meaning "golden colored," an extremely durable mineral found all over the world. This one turned up in a dry, hilly region of Western Australia. It was sitting inside a larger rock, and when scientists checked, it turns out this little grain formed around 4.4 billion years ago.
