Karst Hydrogeology of the Haney Limestone, South-Central KentuckyArpin, Sarah Marie 01 May 2013 (has links)
South-central Kentucky has one of the world’s most intensively studied karstareas, with most work focusing on the Mammoth Cave System and related caves and aquifers. However, slightly higher in the stratigraphic section than Mammoth Cave, the Haney Limestone is a locally important but less well studied carbonate aquifer. This research provides the most comprehensive synthesis to date of the karst hydrogeology of the Haney Limestone of south-central Kentucky, focusing on the distribution and controls on cave and karst features developed within. In contrast to drainage systems within the major limestones below, joints are the most dominant control on passage development in the Haney Limestone within the study area and the orientation of these joints is consistent with that of regional joint sets. Bedding planes and the presence of insoluble rock at the base of the Haney also exert control on conduit development in the Haney Limestone. Most of the caves of the study area developed in the Haney Limestone are singleconduit caves that receive water through direct, allogenic sources. Cave entrances are frequently perennial spring resurgences and the presence of active streams suggests that the caves function within the contemporary landscape, acting as drains for localized recharge areas. The hydrology of the Haney Limestone plays an important, if localized, role in the regional hydrology of south-central Kentucky, integrated into the current system of surface and subsurface drainage of the regional karst landscape. Evidence supports the idea that caves of the Haney Limestone are, geologically, relatively recent phenomena. A majority of the cave passages in the study area are hydrologically active, the water resurging from the sampled springs is typically undersaturated with respect to limestone, and the caves in some case appear to be developed along potential stress release fractures associated with small, apparently young valleys. This suggests that caves in the Haney Limestone were not directly influenced by the incision of the Green River over vast periods, like Mammoth Cave, but that cave development is a largely contemporary process.

National Park Service Cave and Karst Resources Management Case Study: Great Smoky Mountains National ParkNolfi, Daniel C. 01 May 2011 (has links)
As discussed in the National Parks Service’s (NPS) Directors Orders/Natural Resources Management Reference Manual #77 and the 2006 NPS Management Policy Handbook, implementing a management plan specifically for cave and karst resources within a national park is paramount to afford these resources appropriate protection. With support from the Federal Cave Resources Protection Act and the National Park Service Organic Act of 1906, management actions protecting caves has begun to place significant importance outside the traditional cave environment onto a broader karst landscape. The need to understand and protect the karst environment and caves as a karst resource has taken a much larger role in the scientific literature and has increased interest in its federal management application. Proactive management through the use of holistic karst wide management plans and programs is shown to provide superior measures for resource protection when compared to the shortcomings associated with reactive cave focused management. The use of Great Smoky Mountains National Park (GRSM) as a case study supports the need to develop and implement a proactive cave and karst management plan specific to their resources. Management decisions with regards to cave and karst resources currently follow the park's general directives and Superintendent's Compendium. GRSM’s caves and karst areas represent unique resources, such as extensive vertical relief and rare biota, requiring special management in order to effectively protect them and to manage those who study and recreate within them. Characteristics such as these necessitate holistically addressing management of these resources.

Multiple Storm Event Impacts on Epikarst Storage and Transport of Organic Soil Amendments in South-Central KentuckyVanderhoff, Sean M. 01 December 2011 (has links)
The groundwater in agricultural karst areas is susceptible to contamination from organic soil amendments and pesticides. During major storm events during 2011, dye traces were initiated using sulphorhodamine-B, fluorescein and eosine in a groundwater recharge area where manure was applied to the ground. Fecal coliform samples were collected from significant storm events from January-September 2011. Water samples and geochemical data were collected every four hours before, during, and between the storm events from a waterfall in Crumps cave flowing from the known recharge area to track the transport and residence time of the epikarst water and organic soil amendments during variable flow conditions. Two dataloggers at the same waterfall were set up to collect 10-minute data, which included pH, specific conductivity, temperature, and discharge. Total rainfall amount and other surface meteorological data were collected from a rain station located above the cave. Cave water samples were collected for the analysis of anions, cations, bacterial count, and the presence of dye. The dye traces show variability in the characteristics of epikarstic response and flowpaths. The changes in geochemistry indicate simultaneous storage and transport of meteoric water through epikarst pathways into the cave, with rapid transport of bacteria occurring through the conduits that bypass storage. Fecal coliform counts were elevated all through the study period indicating survivability in soils through the seasons. The results indicate that significant precipitation events affect the storage properties and rapidly impact the various pathways and timing of contaminant transport through the epikarst zone, eventually allowing these contaminants to be transported unfiltered in to the groundwater supply. This study shows that current best management practices in karst lands need to be revisited to incorporate areas that do not have surface runoff but where contaminants are transported by seepage into local aquifer.

The search for ancient hair: a scientific approach to the probabilities and recovery of unattached hair in archaeological sitesTurner-Pearson, Katherine 15 May 2009 (has links)
A recent upsurge exists of archaeologists using ancient hair as a research tool, with new uses of this previously discarded archaeological material being introduced annually. Human hair deteriorates extremely slowly, and since the average modern human sheds approximately one hundred hairs per day, there should be copious amounts of hair debris left behind after humans leave a site; it is just a matter of how much of the hair survives in the archaeological environment. Most loose hair recovered from archaeological sites, however, is found fortuitously and in many cases, because archaeologists were not actively searching for ancient hair, it is possible they tainted the hair they later tested in ways that compromised their data, or more importantly contaminated their samples with modern hair and did not test ancient hair at all. No standardized method has previously been established for searching for ancient hair in an archaeological site. This paper considers (a) a method of soil extraction in the field that avoids contamination with modern hair and elements that might hinder later test data; (b) the processing of samples in the laboratory while continuing sample integrity; (c) identification of the types of soils and environments that are most favorable to hair preservation; and (d) an examination of the relevance of hair extraction from sites including the practicality and research potential. This paper examines five archaeological sites, using three different methods of hair extraction, examining the pros and cons of each. This should enable future researchers to find a method that works best for their particular site. It also analyzes the soil chemistry of the sites in order to study the soil and hair survival relationship, so that scientists can better determine which soils hold the best potential for hair survival. Laboratory methods that avoid contamination of the samples are also outlined in order to help researchers keep sample integrity after leaving the archaeological site.

Informal Karst Education in the United States and InternationallyNorth, Leslie A. 01 January 2011 (has links)
Despite the abundance of karst terrains and the important role they play in a wide variety of roles including supplying freshwater drinking supplies, no single, comprehensive study investigates the role of informal education for the improved understanding and protection of the terrains. Commonly overlooked anthropogenic karst disturbances partially occur because of the poor dissemination of scientific information to the general populace and policymakers and budgetary and time constraints of municipalities, thus generating a need to use informal education to fill these shortcomings. The purpose of this study was to: 1) establish the status of and quantify the amount of karst-related informal education efforts pursued in the United States and abroad, 2) reveal if any differences in the nature of educational material exist with ownership (i.e. private vs. governmental) at karst attractions, and 3) evaluate the outcomes of increasing the educational karst material presented to show cave visitors through guided tours. The results of this study reveal that karst education is overall lacking in the United States and internationally, the focus of most recent educational endeavors is bats, and educational programs for children far outnumber the quantity of programs available to adult learners. This research also reveals that disconnects between the actuality of current show cave program characteristics and tour guide and manager opinions about informal karst education are abundant. Furthermore, although differences exist in the nature of the educational material presented to visitors during guided tours, the quality and quantity of material at both privately- and publicly-owned facilities is often significantly lacking. Yet, through field-based research this research proves minimal changes to tour content and guide re-training, can result in successfully increasing visitor karst knowledge while simultaneously maintaining the entertainment value of show cave operations.
