Fractures in till may be horizontal, parallel high- to low-angle, or polygonal (when viewed on a horizontal surface). They have been attributed to several geologic processes, the most important of which are desiccation, freeze-thaw, glaciotectonics, and lodgement till deposition. A literature review, a field study, and core examinations have identified many areas in Ohio where fractures are relatively common. All types of fractures are present within the state, but the depths, relative abundance of types, and their concentrations differ among physiographic regions.
