Citizen Science: Reporting on Wisconsin’s geologic outcrops
Beginning in 1976, geologists at the Survey prepared over 100 descriptions of outcrops from around the state. These outcrops showed important or typical geologic formations, features, and characteristics.
A lot has changed since the descriptions were first written. Narrow roads have been made into 4-lane highways, bypasses have been routed around interesting geology, and roadcuts have been graded and seeded to prevent rock and debris slides. Some of our original outcrops may just be on “old highway xx”; some are on dangerous side roads; some are covered over and lost.
Help us enrich this collection by visiting these outcrops and updating the information. If you send us digital photos of the outcrops, we'll post them along with the descriptions.
Thanks for all your help!
