Kellere Department of Physics, California Polytechnic State University, San Luis Obispo, California 93407 ͑Received 15 February 2010; accepted 27 August 2010͒ We suggest that the existence of many of the rock-carved trails at Racetrack Playa in Death Valley National Park is predominantly due to the effect of arbitrarily weak winds on rocks that are floated off the soft bed by small rafts of ice, as also occurs in arctic tidal beaches to form boulder barricades. These ice cakes need not have a particularly large surface area if the ice is adequately thick—the ice cakes allow the rocks to move by buoyantly reducing the reaction and friction forces at the bed, not by increasing the wind drag. The parameter space of ice thickness and extent versus rock size for flotation is calculated and found to be reasonable. We demonstrate the effect with a simple experiment. © 2011 American Association of Physics Teachers. ͓DOI: 10.1119/1.3490645͔ I. INTRODUCTION literature.

Compare and Contrast the Water Environment Between Death Valley Pupfish Specie and Devil’S Hole Pupfish Specie
Compare and Contrast the Water environment between Death Valley Pupfish Specie and Devil’s Hole Pupfish Specie By Roy Tianran Gao 1 Table of Contents Title page 1 Abstract 3 Introduction and Background 3 Water Temperature 4 Salinity 6 Water Level 7 Conservation 10 Conclusion 11 References 12 2 ABSTRACT The two types of pupfish (Cyprinodon) in Death Valley National Park are Death Valley pupfish and Devil’s Hole pupfish. Death Valley pupfish has been existed over 10,000 years and Devil’s Hole pupfish has been existed for over 20,000 years. Both of the pupfishes are endangered species. The average number of Death Valley pupfish has decreased by about 100 since 1990s, and the number of Devil’s Hole pupfish has decreased by 400 since 1995. Comparing the water level, water temperature and the water salinity between the two species of pupfish would help to define the living requirements and reason of decreasing population. The research toward the result is based on 7 journal articles, 4 websites, and 1 book. As the result shows, Death Valley Pupfish and Devil’s Hole Pupfish live in different water environments and functioned differently. Understanding the water environment of the two types of pupfishes will help people building new habitats for pupfishes and increase their population so that would be possible to avoid the extinction of pupfishes from the earth. INTRODUCTION AND BACKGROUND Pupfish is a small killifish in the Southwest of America. There are five pupfish species in Death Valley which are Armargosa pupfish, Saratoga Pupfish, Devil’s Hole pupfish, Death Valley pupfish, and Cotton ball Marsh pupfish (National Park Service, 2008). -

Phylogenetic Relationships Within the North American Hydrobiid Snail Genus Tgonia: Taxonomic and Biogeographic Implications
Phylogenetic Relationships Within the North American Hydrobiid Snail Genus Tgonia: Taxonomic and Biogeographic Implications Robert Hershleri , Hsiu-Ping Liu2, and Margaret Mulvey3 'Department of Invertebrate Zoology, National Museum of Natural History, Smithsonian Institution, Washington, D.C. 20560; 2Department of Biology, Olin Hall, Colgate University Hamilton, NY 13346; 3Savannah River Ecology Laboratory, P.O. Drawer E, Aiken, South Carolina 29802. Introduction The aquatic biota of western North America is of interest from the standpoint of evolutionary biology and biogeography because elements often are profoundly isolated by inhospitable deserts and mountain ranges, live in extremely restricted and/or harsh environments, and present distributional and phylogenetic patterns which have been molded by the extremely complex and dynamic(Cenozoi physical history of the region. Biotic distributions and evolutionary relationships may also provide clues as to early regional drainage relationships for which geological evidence often/has been obscured by subsequent deposition, deformation and erosion. Whereas early regional biogeographic treatments of fishes (e.g., Hubbs and Miller 1948; Hubbs 1974) focused on dispersal opportunities afforded by a highly integrated late Pleistocene "pluvial" drainage, Minckley et al. (1986) accepted great antiquity (Oligocene- Miocene) of this fauna and consequently emphasized the complex role of geological events in effecting vicariance, and the likelihood that fishes have been introduced to and/or transferred within the region by rafting on allochthonous terranes, intra-continental microplates, and other tectonically displaced or extended crustal fragments. The limited phylogenetic data then available for western American fishes demonstrated partial congruence with hypotheses for historical area relationships advanced by these authors, although they emphasized the need for additional Sich studies. -

William Reamer, Chief HLWB/DWM/NMSS FROM: Jeffrey Ciocco, Hydrogeologist Philip Justus, Senior Geologist Geosciences Section HLWB/DWM/NMSS SUBJECT: DEATH VALLEY WORKSHOP, CONFERENCE ON STATUS OF GEOLOGIC RESEARCH AND MAPPING IN DEATH VALLEY NATIONAL PARK, LAS VEGAS, NV (APRIL 9-11) The conference sponsors included the United States Geological Survey (USGS), U. S. Department of Energy, National Park Service, and Death Valley Natural History Association. The purpose was to foster communication and increase awareness among parties conducting a broad range of geologic research in and around the Death Valley National Park. The program is attached, and the conference proceedings are published in the USGS Open File Report 99- 153 (Slate, 1999). Yucca Mountain is a hydrologic subsystem of the larger Death Valley ground-water flow system. Death Valley serves as the ultimate terminus of the flow system. The conference demonstrated the hydrologic, geomorphologic, hydrogeologic, paleoclimatilogic, and structural importance of this region. Sessions of the conference included: (1) regional structure, tectonics, and bedrock geology; (2) Neogene basin stratigraphy, geophysics, and hydrology; (3) posters on mapping in the Death Valley region and topical ones on Death Valley National Park; (4) imagery, Quaternary stratigraphy and geomorphology, and Quaternary geochronology; and (5) paleoclimate fnd active tectonics. A 1-day field trip was conducted on April 10 to Death Valley. The selection of stops was 2/ determined by the logistics of moving a large group through the Death Valley National Park ancd \ the opportunity to present participants with summaries of recent and ongoing research activities encompassing a broad range of topics. -

A Miniscule System of a 'Sailing Rock'

There exist different theories about how these movements happen, the most recent was that ice-rafts build up below and around the rocks, which are then pushed forward by moving ice floes. Earlier theories regarding this phenomenon describe the influence of wind, and flows of melting water on fine soil material (Hypothesis of ‘Sailing Rocks’). We describe here the same phenomenon, observed not in a large rock weighing several hundreds of kilograms, but in a small pebble of about 2 cm in size. A clear analysis of the conditions under which its movement took place has allowed the formulation of the minimum conditions under which a rock starts moving. Ice rafts may be sufficient but are not necessary. Here we show that pebbles sail driven by the wind over a watery surface that covers an icy but water- saturated substrate, similar to an aquaplaning car.
