Sinkholes are depressions in the ground surface generally associated with subaerially- exposed carbonate rocks that undergo water dissolution over an extended period of time. This weathering process creates a surface depression or a void below ground that either gradually enlarges as loose soil particles are drawn into the sink, or catastrophically collapses when the roof of the subterranean cavity is thinned and weakened. In areas like Jefferson County, Indiana, sinkholes are common, but are not studied or monitored regularly. The existing sinkhole map for Jefferson County is based on a survey of topographic maps provided by the Indiana Geological Survey from more than fifty years ago. Remote-sensing data like LiDAR are extremely useful in recognizing and locating sinkholes for mapping, and in areas underlain by cavernous sinkholes, can lead to a decreased risk to property or injury from collapse if well monitored. Using LiDAR imaging, I aimed to improve the sinkhole mapping available in Jefferson County, Indiana.
