GENERAL INFORMATION

1. Title of Dataset: 
New Surficial Geologic Mapping along the I-65 Corridor in Bullitt, Hardin, and Nelson Counties, Kentucky

2. Description of Dataset:
This project presents new surficial geologic mapping that will address immediate societal needs and support new scientific discovery in an area of west-central Kentucky prioritized with the guidance of the Kentucky State Geological Mapping Advisory Committee (KSGMAC). The new mapping presented represents four new 1:24,000-scale (or greater) surficial geologic maps located along the actively developing I-65 corridor south of the Louisville metropolitan area. The study area is also situated in a geologically unique area that will provide an opportunity to examine relationships of surficial deposits to groundwater resources, geologic hazards (radon, sinkholes, and landslides), and Quaternary landscape evolution of the Midwest United States. This project has been designed to fulfill the long-range mapping plan of the Kentucky Geological Survey and the KSGMAC, will build upon previously funded (FY2013-2014, FY2014-15, FY2015-16, FY2018-2019) U.S. Geological Survey STATEMAP projects along the I-65 corridor, and provide detailed surficial geologic datasets for Bullitt County and Hardin County compilation maps.

METHODOLOGICAL INFORMATION

1. Description of methods used for collection/generation of data:
This map was generated using new field mapping, sample analysis, LiDAR elevation data (5-ft average horizontal spacing), and derivative maps, aerial imagery, and data compiled from water-well logs, oil and gas records, Kentucky Transportation Cabinet geotechnical reports, and landslide inventory mapping from Crawford (2014). Sinkholes in Hardin and Bullitt Counties were identified using the random forests algorithm by Zhu and Pierskalla (2016) and in Nelson Counties by inspection of LiDAR datasets. The extent of colluvium was determined using image classification analysis to detect areas exceeding slope stability (determined at approximately 12° by field evidence). Samples were described by Munsell color and petrography. Grain-size analysis was performed on sediment fractions of less than 2 mm with a laser particle analyzer; results were interpreted using methods discussed in Folk (1966) and grain size is reported using the modified Wentworth scale. Samples representative of major map units were analyzed by X-ray fluorescence and X-ray diffraction for bulk chemistry and mineralogy, respectively. Previously published reports by Peterson (1967) and Arms and others (1971, 1979) and Whitaker and Waters (1986) were also used for interpretation.
