    Hiking

    The water that feeds Dunning Spring comes from near the base of the Galena Aquifer. Beneath this aquifer is the much less permeable Decorah Shale, which acts as a "confining bed" or "floor" for the aquifer. When the Decorah Shale is exposed near the surface of the land, particularly on the sides of river valleys, it causes groundwater to discharge. This process creates beautiful waterfalls and springs, such as Dunning Spring.

    Hiking

    Dunning's Spring Park is named after the waterfall that highlights the area. The trails in the park are well-marked and fairly easy for all trail users. This network of trails connects over to the Barnhart-Van Peenen Park trail system.
