The geologic quadrangle maps for the county were digitized from 2002 to 2007.
The geology of Hardin County consists of Upper Devonian New Albany Shale overlain by Lower to Upper Mississippian-age sequences of limestone, dolomite, sandstone and …
Hypogene Speleogenesis Of Ozark Caves, Jeff Miller
Hypogene Speleogenesis Of Ozark Caves, Jeff Miller
Proceedings of the International Conference on Creationism
This abstract is an update on my continuing study of the origin of north American caves. Since it is difficult to fit carbonic acid dissolution speleogenesis into the timescale of the Creation model, and the Flood model can generate the acidic waters needed for hypogene speleogenesis (HGS), I suggest HGS is the primary mechanism of cave formation. To test this hypothesis, I have been visiting commercial caves to determine what percentage of them show HGS features and are thus likely to have been formed by HGS. This paper offers continuing preliminary results of that test, focusing on the caves of …

Landscape/Atmosphere Interactions And Carbon-Dioxide Dynamics In The Great Onyx Groundwater Basin, Mammoth Cave National Park, Kentucky, Meghan Raines
Masters Theses & Specialist Projects
An increase in atmospheric CO2 since the Industrial Revolution has altered rates of global climate change and has motivated a need to better quantify the flux of carbon between Earth’s reservoirs. Attempts to quantify the exchange of atmospheric carbon between sources and sinks have led to an increasing interest in the terrestrial landscape, including the continental carbon sink associated with carbonate-mineral dissolution. This research sought to better inform an understanding of karst landscapes and their relationship with global climate change through carbon cycling. The study utilized high-resolution data collection of pH, temperature, and specific conductance of waters in the Cascade …
Kentucky Karst Dye Trace Database, Sarah M. Arpin, Benjamin W. Tobin, Maaz Fareedi, Adam Link, James C. Currens
Kentucky Karst Dye Trace Database, Sarah M. Arpin, Benjamin W. Tobin, Maaz Fareedi, Adam Link, James C. Currens
Research Data--KGS
This dataset provides the geographical locations of karst groundwater basins, groundwater flowpaths, and dye injection/recovery points in Kentucky. Dye tracing is a common method used for understanding groundwater movement. Dye is poured (or injected) into a sinking stream, well, sinkhole, or body of water, where it is carried down-gradient by flowing water. The locations at which dye is recovered (typically at artesian springs) indicates a connection from injection to recovery site. This connection is refered to as a groundwater flowpath. Conducting multiple dye traces across an area allows for the interpretation of regional groundwater flow by assessing where flowpaths either …
A Predictive Flood Model For Urban Karst Groundwater Systems, Trayson Lawler
A Predictive Flood Model For Urban Karst Groundwater Systems, Trayson Lawler
Masters Theses & Specialist Projects
Urban karst environments are often plagued by groundwater flooding, which occurs when water rises from the subsurface to the surface through the underlying caves and other karst features. The heterogeneity and interconnectedness of karst systems often makes them very unpredictable, especially during intense storm events; urbanization exacerbates the problem with the addition of many impervious surfaces. Residents in such areas are frequently disturbed and financially burdened by the effects of karst groundwater flooding. The Federal Emergency Management Agency (FEMA) offers limited protection to citizens living near flood-prone areas as they primarily focus on the areas near surface bodies of water. …

Predictive Modeling Of Cave Entrance Locations: Relationships Between Surface And Subsurface Morphology, William Blitch, Adia R. Sovie, Benjamin Tobin
Predictive Modeling Of Cave Entrance Locations: Relationships Between Surface And Subsurface Morphology, William Blitch, Adia R. Sovie, Benjamin Tobin
Faculty, Staff, and Affiliated Publications--KGS
Cave entrances directly connect the surface and subsurface geomorphology in karst landscapes. Understanding the spatial distribution of these features can help identify areas on the landscape that are critical to flow in the karst groundwater system. Sinkholes and springs are major locations of inflow and outflow from the groundwater system, respectively, however not all sinkholes and springs are equally connected to the main conduit system.
Predicting where on the landscape zones of high connectivity exist is a challenge because cave entrances are difficult to detect and imperfectly documented. Wildlife research has a similar issue of understanding the complexities of where …
Comparison Of Groundwater Chemistry And Associated Biodiversity Of Sulfidic Karst Habitats In Southcentral Kentucky, Kendall Wheeler
Comparison Of Groundwater Chemistry And Associated Biodiversity Of Sulfidic Karst Habitats In Southcentral Kentucky, Kendall Wheeler
Mahurin Honors College Capstone Experience/Thesis Projects
In most ecosystems, primary production is conducted by plants or photosynthetic microbes; however, extremophilic sulfur-oxidizing bacteria can use hydrogen sulfide gas (H2S) as an electron donor to produce metabolic energy in a type of metabolism called chemoautotrophy. These ecosystems are a prominent feature of some karst landscapes, and two have been observed in the Mammoth Cave system, Sulphur River in Parker Cave and Marianne’s Pass in Mammoth Cave National Park respectively.
Sulfidic water is ubiquitous in southcentral Kentucky and is strongly associated with hydrocarbon deposits. This oil boom of the 1880s in this region predates most environmental regulation and records …
Hypogene Speleogenesis In The Grand Canyon; Observational, Mineralogical, And Geochemical Investigations From The Bopper Cave System, Sierra Heimel
Hypogene Speleogenesis In The Grand Canyon; Observational, Mineralogical, And Geochemical Investigations From The Bopper Cave System, Sierra Heimel
Theses and Dissertations--Earth and Environmental Sciences
One of the most prominent features of the Grand Canyon is the iron-stained Redwall Limestone, which has been documented to contain extensive cave systems with significant storage potential in the karstic Redwall-Muav (R-M) aquifer. The hydrogeologic relationships between the R-M aquifer and cave formation in the Grand Canyon via descending (epigenic) surface waters have been well documented. However; the potentially large role of deeply sourced (hypogenic) waters rising from depth in relation to cave formation is poorly understood. The Bopper Cave System (BCS) is a relict feature of the ancient abandoned hydrologic system at Grand Canyon and displays unique network …
Hydrogeologic Investigation Of A Covered Karst Terrain, Joseph Peter Honings
Hydrogeologic Investigation Of A Covered Karst Terrain, Joseph Peter Honings
LSU Doctoral Dissertations
Increasing demand for water for agricultural use within the Dougherty Plain of the Southeastern United States has depleted surface water bodies. In karstic landscapes, such as the Dougherty Plain in southwest Georgia where the linkages between surface and ground waters are close, there is a need to understand the physical characteristics of the subsurface that allow these close linkages. Having a better understanding of the subsurface characteristics will aid numerical modeling efforts that underpin policy decisions and economic analyses. Two common features on this karstic landscape are draws and geographically isolated wetlands. Using LiDAR, aerial imagery, and ground-penetrating radar, this …
Geospatial Applications Of Cave Resource Data To Better Understand Epikarst And Unsaturated Zone Groundwater Flow Path Development, Sierra M. Heimel, Benjamin W. Tobin
Geospatial Applications Of Cave Resource Data To Better Understand Epikarst And Unsaturated Zone Groundwater Flow Path Development, Sierra M. Heimel, Benjamin W. Tobin
Faculty, Staff, and Affiliated Publications--KGS
The unsaturated zone is a critical component of karstic groundwater systems and is shown to provide substantial storage capacities. Understanding the spatial patterns and controls on flow path activation is often a challenge. Previous research focused on remotely sensed data or inferential analyses to quantify these patterns. Here, we use two cave systems—one in Arizona, USA and a second in Kentucky, USA—to show the value of the cave survey and inventory data in the direct observation of speleogenesis and unsaturated zone processes. Using geospatial statistical analyses, we show that passage size varies with distance from some faults, indicating that these …

The Flaherty 7.5-minute quadrangle is located southwest of Louisville and northwest of Elizabethtown along the boundary between Hardin and Meade Counties. The quadrangle includes mostly the Pennyroyal region of the Mississippian Plateau and also smaller areas of the Mammoth Cave plateau and the highly dissected Dripping Springs escarpment in the western half of the map area (McDowell, 1986). Topography is mostly characterized by pervasive sinkhole development in a lower elevation and low-relief plain, and high-relief plateaus, ridges, and knobs of the Dripping Springs escarpment scattered along the west side of the quadrangle. Swadley (1963) mapped the bedrock geology of the …
Dye Tracing And The Effects Of Infrastructure In Hidden River Cave, Horse Cave, Ky, Alexa G. Franks
Dye Tracing And The Effects Of Infrastructure In Hidden River Cave, Horse Cave, Ky, Alexa G. Franks
Master's Theses
Hidden River Cave is a stream cave system found in Horse Cave, KY with continuous water flow of its two branches, Wheet River and East River. The infrastructure of the city of Hose Cave, KY was originally designed to utilize natural sinkholes for drainage of all wastewaters. The city uses many of these, now modified, sinkholes for wastewater disposal and storm water drainage. Historically, Hidden River Cave has been severely impacted by unmonitored dumping of contamination. To better understand and identify specific flow paths from sinkholes and infrastructure into Hidden River Cave, this study documented various sinkholes and other infrastructure, …

Abstract
Chemical characterization of clastic cave sediments and insights into particle transport and storage in karst aquifers
Jill L. Riddell
Cave sediments can be divided into two groups: precipitates and clastics. Precipitates are speleothems, or lithologic or mineral features that are chemically precipitated in the cave environment. Clastic cave sediments are frequently described by depositional facies, sorting, and particle size (Bosch and White, 2004). Robust analytical chemical analyses of these sediments to quantify their physical and chemical components is rarely performed although some chemical characterization of mineralogy and paleomagnetism has become prevalent in recent years (Chess et al., 2010; Sasowsky …
Investigation Into Karst Of Southwest Missouri Using Electrical Resistivity, Donald Zachary Wormington
Investigation Into Karst Of Southwest Missouri Using Electrical Resistivity, Donald Zachary Wormington
MSU Graduate Theses
Nixa, Missouri is located on the southwestern edge of the Ozark Dome which has a karst geomorphological environment. Near surface geophysical methods can be used in determining the location and nature of karst features such as caves and sinkholes. Electrical resistivity methods have been shown to be among the most useful methods in deciphering sinkholes and caves. To investigate a known cave and related sinkholes and faults within Mississippian carbonates south of Nixa, Missouri, a series of two-dimensional electrical resistivity profiles were collected using the dipole-dipole and Schlumberger arrays. Terrain data was collected to include in modeling. The data were …

Porosity And Permeability Extremes In An Eogenetic Carbonate Platform: Mechanisms For Formation And Implications For Fluid Flow, Charles I. Breithaupt
Porosity And Permeability Extremes In An Eogenetic Carbonate Platform: Mechanisms For Formation And Implications For Fluid Flow, Charles I. Breithaupt
USF Tampa Graduate Theses and Dissertations
Carbonate rocks contain about a third of the worlds drinking water and host 60-70% of proven hydrocarbon reserves. Effective development and management of these resources relies heavily on geologic concepts used to predict the distribution, and magnitude of porosity and permeability in the aquifer or reservoir. Most geologic concepts used for flow prediction have been developed in telegenic limestones, where fracture networks, bedding plains, and conduits hosted in effectively impermeable bedrock control the movement of fluids, and evolution of porosity. However, a growing body of work has recognized fluid flow within eogenetic limestones is fundamentally different, and that new concepts …
Using Tidal Analysis To Examine Lake-Aquifer Connectivity On A Modern Carbonate Platform, Ronald A. Knoll
Using Tidal Analysis To Examine Lake-Aquifer Connectivity On A Modern Carbonate Platform, Ronald A. Knoll
USF Tampa Graduate Theses and Dissertations
Lake-aquifer connectivity on carbonate platforms is governed by basin morphology which is influenced by diagenetic and depositional processes. Both these processes cause aquifer permeability to vary significantly with scale of measurement (i.e., pore-scale, well-scale, and regional-scale). Because coastal aquifers are well-known to have tidally controlled water level fluctuations, inland lakes may be used to expand the areal measurement of permeability and establish a link between well-scale and regional scale connectivity in the aquifer. To evaluate the impact of lake basin morphology on aquifer connectivity, water level fluctuations were collected at high temporal resolution in the ocean and twenty-four surface water …

Bubble Trail And Folia In Cenote Zapote, Mexico: Petrographic Evidence For Abiotic Precipitation Driven By Co2 Degassing Below The Water Table, Rafael López-Martínez, Fernando Gázquez, José M. Calaforra, Philippe Audra, Jean Y. Bigot, Teresa Pi Puig, Rocío J. Alcántara-Hernández, Ángel Navarro, Philippe Crochet, Liliana Corona Martínez, Raquel Daza Brunet
International Journal of Speleology
Folia are speleothems that resemble bells, inverted cups, or bracket fungi, and whose origins are still controversial. Cenote Zapote (an underwater cave) in the Yucatán Peninsula (México), is home to some of the largest folia reported to date. These speleothems are currently growing in an active underwater system, meaning this site offers an excellent opportunity to constrain the different formation models proposed for folia, which have traditionally relied on inactive examples. In Cenote Zapote, folia are closely related to bubble trails and cupolas, suggesting an underwater CO2-degassing process. In thin section, they display a succession of columnar-open and …

Exploration of the cave has generated research questions about its evolution and geomorphology given the different vadose and phreatic zones impacted by tectonic and incision processes. Dye traces during this study of Cueva de La Peña Colorada confirmed it is a fossil resurgence of the cave system. An additional cave, Cueva Elysium, was connected hydrologically in 2019, expanding the …
Protean Caves And Cyrenean Grottos: The Subterranean World Of Vergil's Fourth Georgic, Kirby Schoephoerster
Protean Caves And Cyrenean Grottos: The Subterranean World Of Vergil's Fourth Georgic, Kirby Schoephoerster
Arts & Sciences Electronic Theses and Dissertations
Using the studies and methodologies spearheaded by the burgeoning field of geomythology, this project aims to reevaluate one of the most famous works of ancient literature, the Georgics of Vergil, within the context of karst geology. In other words, I plan to critically investigate the famous myth of Aristaeus using a geomythological lens that focuses on how Vergil treats caves and cave systems as related to (his) myth. The didactic poem as a whole, and much less so the myth of Aristaeus, has been assessed relatively little by archaeologists, and by geomythologists not at all. Yet, book four contains an …

Spatiotemporal Changes Of Microbial Community Assemblages And Functions In The Subsurface, Madison C. Davis
Spatiotemporal Changes Of Microbial Community Assemblages And Functions In The Subsurface, Madison C. Davis
USF Tampa Graduate Theses and Dissertations
The subsurface hosts diverse microbial community assemblages and functions. These communities play an important role in biogeochemical cycling and groundwater purification. Many physicochemical factors affect microbial communities and can cause short-term or long-term perturbations. Subsurface microbes are susceptible to anthropogenic changes in the environment, which can be caused by nutrient inputs or municipal groundwater extraction. Despite the importance of the subsurface microbiome, these microbial communities are poorly characterized. This dissertation describes the characterization of spatiotemporal drivers of subsurface microbial communities through a variety of techniques that include eDNA analyses, bioinformatics, hydrochemical analyses, stable isotope geochemistry, and multivariate statistics. Three coastal …
