 broad story in the West very broad is it was squeezed and raised and then it fell apart. Do the twist. Every high spot shall be made long. See that the the food is way cool. This rack fell off. This rack fell off. Tritar and I teach a class at Penn State that reaches about 700 students per year. We're working to build an online version of our course to do that. We have this wonderful group of students who are traveling around the West with us learning filmmaking. They will put together materials that then go online so the thousands of students will be able to share in what this small group of students has done. We got to understand the world if we're gonna get along with it and understanding the world is climate and it's living things and ecosystems and its water and its oceans and its ice and its geology. We have taken the really great pieces of geology and set them aside for us to enjoy and us to study. For the public our goal as professors is to have a discourse with everyone because we really do believe it's important we really do believe it matters to real people. Big processes in geology are physics chemistry and biology acting over deep time. Deep time is this notion of the earth being billions of years old. All these different canyons we've seen have been carved by rivers and they've been carved at rates that are remarkably low. A sheet of paper a year and a few million years and you have a canyon. It is an extraordinary notion that water and wind can modify a landscape like this and the only way you can believe it is if you believe that the earth is billions of years old. Charles Darwin came along he came up with this wonderful elegant theory called evolution and his theory needed time and the geologists are the ones that came along and said you got all the time in the world because the earth is old. Your theory can work because we got all the time in the world for you and it's recorded in the rocks. Notice and by itself doesn't stick together at all it's very loose and it bounces around and it's very easy to blow and I just made a little sand dune you'll notice that I eroded on this side and I deposited on this side. Well that's a conglomerate isn't it? It is. Look at that babe that's the conglomerate we were looking for. That's beautiful. Before the hooters formed it was one solid rock layer and when rain came from above... Okay so what this is and again I think I told most of you this already this is an old fiddle tune called Red Wing. It exists in a whole bunch of different forms over the years including a song by Woody Guthrie who set words to it that are completely different but it's got a catchy tune. To break the film so rain begins to sculpt the arching show on Mesa Verde's crown Caves ring it all around Ancestral Pueblo people live till dryness force him down And the rivers are carving through the deeper timetaps Garving ever deeper through the red rocks May they keep carving forevermore This is spectacular look at that look at that oh my god oh my god look at that we sat there last night in the Green River overlook and watched the sunset over the green and canyon lands and it was just breathtaking and I've occasionally heard this bizarre fiction that somehow being interested in this understanding this knowing the research of it in the depth of it takes away the beauty and all you see is a subject for experimentation and it was gloriously beautiful I do love what I do I do love geology and I'm not sure why it's beautiful the patterns are sweet I like what I see I like getting under the skin of the earth and understanding why it is where it is I believe it's useful I believe that we're doing things that will help people I know we're doing things that are fun
