QUATERNARY GEOLOGIC MAP of AUSTIN 4° X 6° QUADRANGLE, UNITED STATES
QUATERNARY GEOLOGIC MAP OF AUSTIN 4° x 6° QUADRANGLE, UNITED STATES QUATERNARY GEOLOGIC ATLAS OF THE UNITED STATES MAP I-1420 (NH-14) State compilations by David W. Moore and E.G. Wermund, Jr. Edited and integrated by David W. Moore, Gerald M. Richmond and Ann Coe Christiansen 1993 NOTE: This map is the product of collaboration of the Texas Bureau of Economic Geology and the U.S. Geological Survey, and is designed for both scientific and practical purposes. It was prepared in two stages. First, the map and map explanations were prepared by the State compiler. Second, information on the map was integrated with that of adjacent maps, locally supplemented, and related to a uniform map symbol classification by the editors. Map unit descriptions were edited, supplemented, and coordinated with those of other maps of this series so that individual unit descriptions are applicable throughout both this map and all other maps of the series. Problems of mapping or interpretation in different areas were resolved by correspondence to the extent possible; most simply reflect differences in available information or differences in philosophies of mapping and serve to encourage further investigation. Less than forty percent of the surficial deposits of the United States have been mapped and described. Traditionally, mapping of surficial deposits has focused on glacial, alluvial, eolian, lacustrine, marine, and landslide deposits. Slope and upland deposits have been mapped in detail only in restricted areas. However, an enormous amount of engineering construction and many important problems of land use and land management are associated with regions that have extensive slope and upland deposits (colluvium and residuum, for example). -

McCoy , August 2011 Acknowledgements I would first like to thank my wonderful and thoughtful husband, Travis. Your unconditional love, support, and humor have brought me through some hard times. I would not be where I am without you and our fur-babies, Wednesday, Katt, and Bear. I would like to extend my gratitude and appreciation to my thesis advisor, Dr. Tom Lehman, and my thesis committee, Drs. Eileen Johnson, Hal Karlsson, and Peter Holterhoff. Dr. Lehman, your educational guidance, which often took the form of weekly pep-talks and humor-laden e-mails, has proved to be invaluable in the course of this research. The extent of your knowledge in geology and, for that matter, silcretes, which apparently only six people in the whole world care about, still astounds me. Dr. Lehman, I guess you are one of those six people, afterall. Dr. Johnson, your financial support during my time at Texas Tech is greatly appreciated. Also, your constructive criticism and knowledge of Southern High Plains archaeology has proved invaluable in finishing this project. Dr. Karlsson, thank you for your help in stable isotope geochemistry and hydrous minerals. -
A Big Colorful Hole in the Ground
A Big Colorful Hole in the Ground The first account I had of Palo Duro Canyon was from my son. He had been out to Lubbock to attend the swearing in of a friend from college as a County Judge. My nephew, Ben, who lives in Lubbock, said, because my son had some free time, they should go see Palo Duro Canyon. So, according to my son’s account, “Off we went at a high rate of speed” as the West Texans are disposed to do. My immediate family members are life-long residents of the coast and East Texas. We are accustomed to seeing trees and lots of greenery. The cap rock country is a different world to us. “We were cruising along slightly below the speed sufficient to become airborne, in that barren desert country,” my son recalled. “Ben told me I would not believe my eyes, and I did not!” ”! After a few twists and turns off the interstate, a road plunged down 800 feet into a vast depression in the ground. And this is exactly as I found it some years later. We went there to camp in the canyon and see this marvelous 16 thousand acre plus Texas treasure, The Grand Canyon of Texas (and the second largest canyon in the US). The multi-colored canyon walls were striking but had little effect on Brigid. Her first sighting of a flock of wild turkeys that came “grazing” by our camper about day break was quite another matter. Her behavior reminded me of that of our son when at 5 years of age he saw an elephant for the first time. -

Observations of Turbulent Kinematics and Lightning-Inferred Electric Potential Structure in a Severe Squall Line Eric C
XV International Conference on Atmospheric Electricity, 15-20 June 2014, Norman, Oklahoma, U.S.A. Observations of turbulent kinematics and lightning-inferred electric potential structure in a severe squall line Eric C. Bruning1∗ Vicente Salinas1, Vanna Sullivan1, Scott Gunter1, and John Schroeder1 1Texas Tech University, Lubbock, TX, U.S.A. ABSTRACT: Recent work by Bruning and MacGorman [2013] proposed an energetic measure of lightning flashes based on flash size (area) and rate. The resulting energy spectrum as a function of flash size had a consistent shape, and had an apparently linear scaling regime at the same length scales where a turbulent thunderstorm’s inertial subrange would be expected. They hypothesized that electrical potential was organized by the (possibly turbulent) character of the convective flow. Since then, flash extent has also been applied to the energy available for NOx production by lightning, and the geometric, space-filling character of the lightning channel itself. A severe squall line that moved across West Texas on the night of 5 June 2013 caused extensive dam- age, including much that was consistent with 80-90 mph winds in the vicinity of Lubbock. The storm was samplednear Pep, TX during the onset of severe winds by two Ka-band mobile radars operated by Texas Tech University (TTU), as well as the West Texas Lightning Mapping Array (WTLMA). In-situ observa- tions by TTU StickNet probes verified the severe winds. Vertical scans with the radars were taken ahead of the storm and continuously for one hour behind the line in conditions consistent with the conceptual model for the transition zone of a mesoscale convective system. -

Phase II Contaminants Investigation of Buffalo Lake National Wildlife Refuge, Texas 1993-1994
U.S. Fish and Wildlife Service Region 2 Contaminants Program PHASE II CONTAMINANTS INVESTIGATION OF BUFFALO LAKE NATIONAL WILDLIFE REFUGE, TEXAS 1993 - 1994 by Denise L. Baker 1, Joel D. Lusk 2, and Craig M. Giggleman U.S. Fish and Wildlife Service Arlington Ecological Services Field Office 711 Stadium Drive, East, Suite #252 Arlington, Texas 76011 September 1998 PHASE II CONTAMINANTS INVESTIGATION OF BUFFALO LAKE NATIONAL WILDLIFE REFUGE, TEXAS 1993 - 1994 ABSTRACT Buffalo Lake National Wildlife Refuge is located in the Southern High Plains in Randall County, Texas. The lake from which the Refuge received its name has not contained water since the 1980s. In 1987, a Phase I contaminants investigation of the Refuge was conducted by the U.S. Fish and Wildlife Service, Arlington, Texas, Field Office. The results of this investigation indicated that elevated concentrations of nutrients (nitrogen and phosphorus compounds), salts, copper, strontium, and zinc were found in and downstream of cattle feedlot waste retention lagoons; Tierra Blanca Creek, the major lotic contributor of the Refuge, had degraded water quality, primarily attributed to run-off and discharges from cattle feedlots; and that nutrient concentrations retained in soils in the dry reservoir bed in Buffalo Lake National Wildlife Refuge were elevated to the extent that inundation could create unacceptably high nutrient concentrations in the surface water. Consequentially, in 1993, a Phase II contaminants study was initiated at the Refuge by the U.S. Fish and Wildlife Service to evaluate the extent of contamination in stormwater run-off entering the Refuge via Tierra Blanca Creek; to determine the extent of contamination in soils and vegetation within the Refuge; to evaluate the ability of crops grown in the Refuge to reduce soil contaminant concentrations; and to monitor contaminant levels in soils, surface water, and vegetation of moist soil management units constructed in the southern portion of the Refuge. -

Geological information is no exception, but in Texas such data are often readily at hand. The state has one of the highest concentrations of practicing geologists per capita in the United States; and Texans in general are very conscious of the importance of fossil fuels, earth materials, and land and water resources in the state's economy, history, and quality of life. -

Fisher, Director The University of Texas at Austin University Station, P.O. Box X Austin, Texas 78713 1983 I I 3.3.2.4 Jointing History I Joints are fractures in a rock that exhibit no detectable displace ment between one face of the fracture and the other. Previous work on I the origin of joints has determined different mechanisms to explain I 'fracturing. Some researchers have explained joints in terms of their relationship to tectonic deformation and major structural elements I (Harris and others, 1960; Price, 1966; Stearns and Friedman, 1972). Others have shown that joints may develop independently from tectonic deformation I and that joints may form in sedimentary rocks early in their history (Parker, I 1942; Hodgson, 1961; Price, 1966; Cook and Johnson, 1970). Price (1974) investigated the development of joints and stress systems in undeformed I sediments during the accumulation of a sedimentary series, its downwarping and subsequent uplift, and accompanying de-watering of the sediments: Joints I can also result from unloading due to erosion (Chapman, 1958). The formation of I joints in sedimentary rocks is dependent on three factors (Hobbs, 1967): (1) physical properties of both the fractured rock bed and the surrounding I rock beds; (2) thickness of the rock bed; and (3) degree of tectonic deforma tion of the beds.
