Information Circular--KGS
Over the last 20 years, researchers at the University of Kentucky have collected seismic-reflection and refraction data to characterize seismic velocity models of the soil-sediment overburden throughout the central United States. The data are in different forms, such as published reports, theses, and journal articles, and in digital form. In order to construct a unified database for easier management, access, and use, Microsoft Access was used to design the data structure and field properties. The database consists of four tables with unified field names, data type, and units. An ArcGIS geodatabase with the same data structure as the Access database …

Joint Orientations In The Red River Gorge Geological Area, East-Central Kentucky, Steven L. Martin
Information Circular--KGS
The Red River Gorge Geological Area and Clifty Wilderness Area of Daniel Boone National Forest and Natural Bridge State Park in east-central Kentucky provide an excellent opportunity to observe and study differential weathering and erosion, mass wasting, and jointing in the development of cliffs, rock shelters, and natural arches. Joints in the study area have varying orientations, but dominant northeast- and northwest-striking orientations are prevalent. Jointing in the study area is related to unloading of overburden and regional tectonic stresses. Unloading joints result from removal of overburden from a rock mass, and orientations of joints are controlled by either residual …
