Save to calendar
Long ago, the potholes and their depths were a mystery. Today, discover the measurements of several of them using the sounding technique of early explorers. Make guesses about pothole depths and receive prizes for the closest. This is a great walk for parents and children. Meet at the Visitor Center. This program is free, but a Minnesota State park vehicle permit is required of any vehicle entering the park. This permit can be purchased at the park entrance office for $5/day or $25/year.
