2001 INVENTORY OF PALEO RESOURCES FROM NPS CAVES 1 AN INVENTORY OF PALEONTOLOGICAL RESOURCES ASSOCIATED WITH NATIONAL PARK SERVICE CAVES ABSTRACT More than 3,600 caves and karst resources have been identified in at least 79 units of the National Park System. In 1998, the National Park Service Geologic Resources Division initiated a servicewide inventory of paleontological resources occur- ring in association with these caves. The inventory documented at least 35 park areas that preserved fossils within cave resources. Cave-paleontological resources are identified in two categories: 1) fossils preserved within the cave-forming bedrock, and 2) fossils accumulated within the caverns, chambers, or other openings in karst systems. Caves occur in both karst and non-karst areas. Karst caves, and features within them such as stalactites and stalagmites, are formed by a variety of processes. These processes include the dissolution and erosion of sedimentary and evaporitic rocks, and later deposition of minerals from the dissolution process. Within limestones, the remains of marine invertebrate and vertebrate fossils are typically preserved. Paleozoic limestones constitute the parent rock in which many cave and karst features develop in NPS administered areas. Therefore, the fossilized remains of Paleozoic fauna are often the most common types of paleontological resource associated with caves. Caves also form as the result of lava flows (lava tubes), wave action (littoral caves), and by the fracturing of rock (earth cracks). Cave feature development is documented from the Holocene back to the Eocene. Caves, sinkholes, solution tubes, and other karst features attract and can trap animals. Pleistocene and Holocene vertebrate remains are abundant in many caves. Rich deposits of fossil bone can develop either through the accumulation of remains associated with organisms inhabiting the cave, such as Neotoma (packrats), or through a variety of transport mechanisms.

    United States Department of Agriculture Wilderness Visitors and Forest Service Recreation Impacts: Baseline Rocky Mountain Research Station Data Available for Twentieth General Technical Report RMRS-GTR-117 Century Conditions September 2003 David N. Cole Vita Wright Abstract __________________________________________ Cole, David N.; Wright, Vita. 2003. Wilderness visitors and recreation impacts: baseline data available for twentieth century conditions. Gen. Tech. Rep. RMRS-GTR-117. Ogden, UT: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 52 p. This report provides an assessment and compilation of recreation-related monitoring data sources across the National Wilderness Preservation System (NWPS). Telephone interviews with managers of all units of the NWPS and a literature search were conducted to locate studies that provide campsite impact data, trail impact data, and information about visitor characteristics. Of the 628 wildernesses that comprised the NWPS in January 2000, 51 percent had baseline campsite data, 9 percent had trail condition data and 24 percent had data on visitor characteristics. Wildernesses managed by the Forest Service and National Park Service were much more likely to have data than wildernesses managed by the Bureau of Land Management and Fish and Wildlife Service. Both unpublished data collected by the management agencies and data published in reports are included. Extensive appendices provide detailed information about available data for every study that we located. These have been organized by wilderness so that it is easy to locate all the information available for each wilderness in the NWPS. Keywords: campsite condition, monitoring, National Wilderness Preservation System, trail condition, visitor characteristics The Authors _______________________________________ David N.

  • Maya Settlement Patterns and Land Use in Buena Vista, Cozumel, México
    FAMSI © 2004: Adolfo Iván Batún Alpuche Maya Settlement Patterns and Land Use in Buena Vista, Cozumel, México Research Year: 2003 Culture: Maya Chronology: Post Classic Location: Cozumel, México Site: Buena Vista Table of Contents Abstract Resumen Introduction Project Goals Research Design and Methods Preliminary Results Microenvironmental Zones Main Transects Transects Limiting Quadrants Selected Areas Soil Profiles Summary and Conclusion Acknowledgments List of Figures Sources Cited Abstract The Buena Vista Archaeological Project is a study of postclassic Maya settlement patterns and land use on the island of Cozumel, México. Field work carried out in the site during the months of June–August 2003 was sponsored by the Foundation for the Advancement of Mesoamerican Studies, Inc., (FAMSI). Previous archaeological research in Buena Vista had focused in a central area of seven hectares and reported the existence of an extensive wall system and platforms at the site which was interpreted as a storage center for exchange and resupply transactions. In this interpretation, the platforms supported perishable structures used to store trade commodities, and the wall system was built to protect these trade goods from possible pirate attacks (Sabloff and Rathje 1975, Freidel and Sabloff 1984). However, the nature and extension of the wall system around the central area had not been investigated in detail. The research objectives of this project were to analyze the Buena Vista settlement pattern following a settlement ecology model (Stone 1996, Killion 1992), which seeks to understand the relationship between population and agricultural practices in an ecological setting. The project followed a program of surface survey and mapping of the wall system, related structures, and natural features located in an area of 4 km2 around the center of the site.

Miller2, and Thomas H. Morris2 ABSTRACT.—While a variety of mammalian megafauna have been recovered from sediments associated with Lake Bonneville, Utah, sloths have been notably rare. Three species of ground sloth, Megalonyx jeffersonii, Paramylodon har- lani, and Nothrotheriops shastensis, are known from the western United States during the Pleistocene. Yet all 3 are rare in the Great Basin, and the few existing records are from localities on the basin margin. The recent discovery of a partial skeleton of Megalonyx jeffersonii at Point-of-the-Mountain, Salt Lake County, Utah, fits this pattern and adds to our understanding of the distribution and ecology of this extinct species.

  • New Species of Snake Described with the Help of a 185-Year-Old Painting 14 May 2021
    New species of snake described with the help of a 185-year-old painting 14 May 2021 Since it is so widespread, many people have studied these snakes and given them lots of different names." "But one of the biggest problems is that the names between two of the most common species of snakes found in India have been frequently confused." This confusion can be traced back to a scientist called Albert Günther, who worked at the Museum between 1875 and 1895 and originally mixed up the species. The new species has been named Joseph's racer, Platyceps josephi, after a late colleague of the researchers. Credit: Surya Narayanan The species of snake that has caused all this confusion was previously known as the banded racer, or Argyrogena fasciolata. The description of this species was, in part, based on snake skins A new snake species has been described from the collected in 1796, which are now part of the Indian state of Tamil Nadu. The new species, now Museum's collections. known as Joseph's racer, was first collected in the mid-19th Century, but the confusion around this This gave Deepak the extraordinary chance to go snake goes back over two centuries as it has been back to these original collections and reassess the mixed up with another similar species found across snakes.
