The department’s Missouri Geological Survey provides assistance to citizens by performing geologic evaluations to aid in determining if a collapse is attributed to a natural karst feature, such as a sinkhole, or is associated with the failure of a man-made feature.Sinkholes are a characteristic featuer of a karst terrain. In well-developed karst terrain, chains of sinkholes form what are known as solution valleys and streams frequently disappear underground. Sinkhole collapse, either slow or dramatic, can cause considerable damage to buildings, highways, rails, bridges, pipelines, storm drains, and sewers.
