This dataset contains digitized points for cover-collapse, karst sinkhole locations using bare-earth lidar elevation data for the State of Illinois acquired during the leaf-off periods of 2009, 2011-2012, 2014-2015, and 2017-18. Each sinkhole point is assigned a unique identification number, the elevation at the base of the sinkhole feature, the geologic formation in which the sinkhole is developed, the prevailing land cover, the Illinois County name, and the specific latitude/longitude location.
