  1. Billy-
    What an excellent, informative, and charming video you have here. Well done, sir. I hope you are having fun up North. Take ‘er easy.

  2. love the NYC analogy, and the soda in the straw analogy too. makes it really easy to understand. so THAT’S what you guys are doing up there. i get it! but now of course it just makes me want to learn more about what the next steps are–how you take a hockey puck of mud and figure out what the climate was like thousands of years ago. i’ll stay tuned…

  3. billy, i am a friend of your father and also a retired earth science teacher. i’m impressed that you are able to explain what you are doing in plain english. the fact that you can do so in understadable terminology with practical examples makes this a great resource. i will pass your website on to other earth science teachers.

  4. really nice video; i need this for my limnology classes! cool stuff
