Technical Abstract: A review of Ohio's geological and soils literature indicates that while the first descriptions of "joints" in clay tills were made in 1880, the first comprehensive inventory of fractures were made by Ohio's soil scientists. In March 1993, a working group was called together by The Ohio State University and Bennett & Williams, a private consulting company. The working group organized a one day field event, August 28, 1997. The site was a large, three tiered pit approximately 11 meters x 26 meters and 3.5 meters deep. This site was manned by glacial geologists and soil scientists. The site, which required three days of preparation by as many as 15 people, was used to demonstrate: 1) the soil profiles and how they were formed, 2) the relationship of the underlying glacial till deposits with associated polygonal fracture patterns and 3)the difference in unsaturated hydraulic conductivity between area of fractures and areas of no fractures. The Lake Plains Working Group, now undergoing renaming to reflect their larger mission, are currently planning additional educational outreach efforts. Five presentations will be made at the 1998 Annual Meeting of the Ohio Academy of Science, summarizing the research for 1997. A special issue of the Ohio Journal of Science is being planned to fully document the research efforts here in Ohio and create a summary of efforts under way around the world.
