Those living in Fillmore County and in the Harmony area, are likely familiar with the phenomena of sink holes and the aspects of the karst geology that exists in this area. However, there is more to learn and the Harmony Area Historical Society has made a commitment to provide information about the area's karst limestone formations to both local residents and to visitors to the area.
