Photographic And Sediment Monitoring Procedures And Initial Results For A Brazilian Iron Ore Cave, Vitor Moura, Augusto Auler, Marina Leão, Luciana Alt

National Cave and Karst Management Symposium 2013

The definition, development and application of monitoring procedures for caves are currently in demand in Brazil. The need for environmental licensing processes and effective environmental control actions has been increasing since the beginning of this century due to the intensification of economic activities.

This work discusses the development of a method of photographic and sediment monitoring and the application of this method in an iron ore cave.

Icaverns: Interpretation, There's An App For That!, Sandra Dianne Joop

National Cave and Karst Management Symposium 2013

A quarter of a century ago, cave and karst resources were declared irreplaceable with the passing of the Federal Cave Resources Protection Act. Yet, today, few understand the importance or fragility of these resources. Human interactions in karst areas make these resources highly susceptible to damage. Nonpersonal interpretation digital media products could serve as an important tool to bridge this informational gap.

Worldwide, there are hundreds of parks or parklike attractions focusing on cave, spring, or sinkhole resources. Their visitors have a built-in curiosity about these places. Engaging this audience in interpretive programming could greatly increase their speleological knowledge. Paradoxically, …

National Cave and Karst Management Symposium 2013

Belize is a developing country that faces water resource issues in the forms of both quality and quantity, stemming from a long history of environmental stress and population threats, from the ancient Maya to present. Belize’s karst landscape, which comprises a large part of the country from the coast to the Maya Mountains, is characterized by springs, caves, sinkholes, and aquifers systems formed from the dissolution of carbonate (limestone, dolomite) rock. This research presents several different case studies, spanning from the ancient Maya and issues with drought to modern communities that rely on groundwater resources quickly being depleted. Past drought …

Postglacial Faunal Records From Cave Deposits In Jasper National Park, Alberta, Canada, Christopher N. Jass, Greg Horne, Dave Critchley

National Cave and Karst Management Symposium 2013

In 2009, we initiated an on-going, long term research project that focuses on exploration of fossil-bearing cave deposits in Jasper National Park. Specifically, we were interested in understanding patterns of mammalian re-colonization of mountainous regions following late Pleistocene deglaciation. Our work has focused on the identification of fossil-bearing cave deposits, excavation and sampling of those deposits, and radiocarbon dating of recovered remains. Examined sites have at least an age of 9600 years BP. Research at four cave sites, located in relatively close proximity to one another, is contributing to an improved understanding of the late Quaternary record of Jasper National …

Understanding A Globally Unique Nexus Of Acid Mine Drainage, Karst And World Heritage Site, Philip J. Hobbs, P.J. (Peter) Mills

National Cave and Karst Management Symposium 2013

The Cradle of Humankind World Heritage Site (COH WHS), South Africa, is the only UNESCO-protected karst landscape in the world that is under threat from acid mine drainage (AMD). This has generated wide and considerable concern for the preservation of the fossil sites and karst ecosystems of the WHS. A recent assessment of the water resources environment and continued water resources monitoring has better informed this situation, providing support for management efforts to protect the aquatic environment and outstanding universal value of the site.

Paleohydrology And The Origin Of Jewel Cave, Mike Wiles

National Cave and Karst Management Symposium 2013

With more than 267 m (166 miles) of mapped cave passages, Jewel Cave is the third longest cave in the world. The passages are beneath an area of 775 ha (3 mi²), located almost entirely within the Hell Canyon drainage basin. The canyon itself is situated in the bottom of a south-plunging syncline and most of the cave passages are located within the east limb. A down-dip cross section shows the cave passages assuming the shape of an elongate lens, located just below the Pahasapa/Minnelusa contact. The lower boundary is a maximum of 75 m (250 feet) below …

Caver Quest 3d Virtual Cave Simulation Of Snowy River In Fort Stanton Cave, Ronald J. Lipinski, Pete Lindsley

National Cave and Karst Management Symposium 2013

Virtual worlds, or 3D simulations through which an avatar can travel, is becoming a common means to display products or provide training in new environments. This paper describes the steps in producing the 3D virtual simulation of Snowy River in Fort Stanton Cave, New Mexico. A traditional cave survey and map with cross sections was used to produce a 3D meshed surface of the cave walls using the Blender software package. Photographs were taken of the walls, ceiling, and floor and merged together. The merged montage was applied to the 3D mesh walls as a “texture”. Unity3D was used to …

The Nps Cave Visitor Impact Vital Signs Monitoring Protocol, Rodney Horrocks

National Cave and Karst Management Symposium 2013

The national Cave Visitor Impact Vital Signs Monitoring Protocol is an attempt to standardize visitor impact monitoring in all National Park Service managed caves. With standardized monitoring in place, it will be feasible for the first time to compare monitoring data from caves across the country. This cave monitoring protocol was initiated at the NPS Cave Vital Signs Workshop held in Lakewood, Colorado in 2008. That workshop identified the vital signs that were common to all caves, including cave visitor impact. A committee convened at that workshop decided that the cave visitor impact monitoring protocol would address four parameters of …
