Be a geologist for a day as you travel through the southwest United States studying dramatic rock formations and learning what they tell us about Earth's past — and future. Segments include:

Rocks: Arizona is a great natural laboratory for geologists. Travel with a film scout as he checks out igneous, sedimentary, and metamorphic rock formations for possible backdrops.
Erosion: The Earth may appear unchanged to us, but it is actually being forever reshaped by erosion over long periods of time. Learn how when the conditions are right, this long-term erosion can turn into a sudden and violent event — a landslide.
Grand Canyon: Explore the Grand Canyon and learn how this natural wonder was formed through a combination of erosion and shifting tectonic plates. And see how geologists search the canyon's sandstone layers for clues to the history of the Earth.
