Where does sand originate? How does it get into rivers and eventually the sea, or the desert? Explore these questions on local field trips, and put some sand under a microscope to learn more about how geologists view these fascinating grains. Then go west to the Colorado Plateau to see how modern winds are moving sand into ripples and dunes. Explore Zion National Park to learn about the deposition of ancient sandy deserts. Learn how geologists know that some of this sand in Utah came from the ancient Appalachians. Return home to explore the Appalachians to learn about long-ago seas and beaches, and rivers that carried the sand away from the Appalachians when coal swamps were forming in West Virginia. This is all what the GEOL 105: Earth Lab: SAND! class, Spring 2013 did!
