Conditions for Sinkhole Development

	Bare or thinly covered limestone. Sinkholes are few, generally shallow and broad and develop gradually. Solution sinkholes dominate.
	Cover is 30 - 200 feet thick. Mainly incohesive and permeable sand. Sinkholes are few, shallow of small diameter and develop gradually. Cover-subsidence sinkholes dominate.
	Cover is 30 - 200 feet thick. Mainly cohesive clayey sediments of low permeability. Sinkholes are most numerous, of varying size, and develop abruptly. Cover collapse sinkholes dominate.
	Cover is more than 200 feet thick. Cohesive sediments interlayered with discontinuous carbonate beds. Sinkholes are very few, but several large-diameter, deep sinkholes occur. Cover-collapse sinkholes dominate.
