Flaming Meteors, Dark Caves, and Raging Waters - Geological Curiosities of Western WI

Primary Leader: Jean Cunningham
Leader(s): William S. Cordua, S. Blaze Cunningham, Holly A.S. Dolliver
Field Trip Description: This one-day trip will introduce educators to some of the unique geological features of Western Wisconsin that can be incorporated into any K-12 science program. Four strikingly different stops will show you how to expose students to geology in the field. Crystal Cave, located in Spring Valley, is Wisconsin's longest cave at over 1km. The educational tour will take you 70 feet below ground, into a dynamic cave with active speleothem development. The Cave offers a distinctive educational program designed to expose students of all levels of the sciences of caves. A nearby stop will feature the Largest Earthen Dam in the Midwest. Built in the late 1970's for flood control, this stop offers a great place to learn about watersheds and how they affect our lives. Nearby is the site of an historic iron mining and smelting operation active from 1890-1910. The ore deposits, called bog ore, are probably related to Cretaceous weathering of Ordovician carbonates. The mining and processing of these rich deposits fueled a boom in the village of Spring Valley. This is a great location to learn how geology can influence history. To the south is the Rock Elm Disturbance, a 6 km wide Ordovician bolide impact site. One of less than 200 known impact sites, you'll see deformed stratigraphy which until recently was poorly understood. You'll take a short hike to examine the destructive power of meteors. Join us on this fun trip!
Field Trip will span: 1 day
