Description: This map layer contains known landslide locations (points) across Kentucky compiled in a landslide inventory database. The locations come from Kentucky Geological Survey research, state and local government agencies, and the public. Many of the points represent larger landslide features that have not been mapped in detail and may fall within different parts of the slide area (crown, head scarp, middle, or toe). The landslides are active or have historically been active. Slide locations are collected at different times and contain varying amounts of attributes. The inventory does not capture work by private industry or other agencies that document landslides but do not make them available. Many attribute values are "Null" and data is only present if the slide was visited or could be collected another way. Landslide inventory points that fall within a landslide polygon layer represent the centroid of that polygon so it could be catalogued in the inventory database.
The SourceDesc field describes the source of the landslide location.

Description: These landslide locations (polygons) were mapped on the 7.5-minute, 1:24,000-scale geologic quadrangles published jointly by the Kentucky Geological Survey and US Geological Survey from 1960 to 1978. Attributes include original map symbol and formation name, as well as county, quadrangle, and Area Development District. Landslides were not mapped on all quadrangles.
Description: These landslides (polygons) were mapped using 1 m resolution (horizontal) Light Detection and Ranging (LiDAR) data. Using hillshade digital elevation models, potential landslide locations were identified and digitized. Locations were field verified, where possible. Comments included are notes and observations taken during the mapping of these slides. For more information regarding these landslides and LiDAR see KGS RI_24_12.

Description: This layer (polygons) represents mapped landslides including earthflows, debris slides, and slumps. The data come from a series of Landslide and Related Features Maps and Landslide Potential Maps that cover most of southeastern and south-central Kentucky. Landslides were interpreted from aerial photographs and historical records. The features digitized (lines) depict generalized slope conditions as they existed at the time of field checking (1977-1981). Slope stability may decrease by excavation, loading, and changes in drainage conditions. The data are from preliminary type maps and are suited for general planning purposes only.
Description: This layer (lines) represents debris flow deposits or areas susceptible to debris flows. Primarily these areas are shallow, narrow ravines containing variable accumulations of colluvium. The data come from a series of Landslide and Related Features Maps and Landslide Potential Maps that cover most of southeastern and south-central Kentucky. The features were interpreted from aerial photographs and historical records. The debris flows digitized depict generalized slope conditions as they existed at the time of field checking (1977-1981). Areas of thick colluvium are susceptible to rapid movement during intense rainfall. The data are from preliminary type maps and are suited for general planning purposes only.
