AREA I. BARE OR THINLY COVERED LIMESTONESinkholes are few, generally shallow and broad, and develop gradually. Solution sinkholes dominate.AREA II. COVER IS 30 TO 200 FEET THICKConsists mainly of incohesive and permeable sand. Sinkhole are few, shallow, of small diameter, and develop gradually. Cover-subsidence sinkholes dominate.AREA III. COVER IS 30 TO 200 FEET THICKConsists mainly of cohesive clayey sediments of low permeability. Sinkholes are most numerous, of varying size, and develop abruptly. Cover-collapse sinkholes dominate.AREA IV. COVER IS MORE THAN 200 FEET THICKConsists of cohesive sediments interlayered with discontinuous carbonate beds. Sinkholes are very few, but several large diameter, deep sinkholes occur. Cover-collapse sinkholes dominate.
