Total damage repair costs from an engineering judg- ment prediction are provided. Spectral Matrix Method calcula- tions are now in progress. Also included are general safety recommendations. A summary of predictions follows: Structural Response Damaging motions are probable in the region inside 25 kilometers. Structural hazards exist in Grand Valley, at the Anvil Points Research Station, and at various small ranches out to a distance of 14 ki lometers from Ground Zero (GZ) . The area is much more densely populated than would appear from initial project informa- tion. Earth Structure Hazards Rockfall and hazards to slope stability create major problems. -
Geologic Map of the Central San Juan Caldera Cluster, Southwestern Colorado by Peter W
Geologic Map of the Central San Juan Caldera Cluster, Southwestern Colorado By Peter W. Lipman Pamphlet to accompany Geologic Investigations Series I–2799 dacite Ceobolla Creek Tuff Nelson Mountain Tuff, rhyolite Rat Creek Tuff, dacite Cebolla Creek Tuff Rat Creek Tuff, rhyolite Wheeler Geologic Monument (Half Moon Pass quadrangle) provides exceptional exposures of three outflow tuff sheets erupted from the San Luis caldera complex. Lowest sheet is Rat Creek Tuff, which is nonwelded throughout but grades upward from light-tan rhyolite (~74% SiO2) into pale brown dacite (~66% SiO2) that contains sparse dark-brown andesitic scoria. Distinctive hornblende-rich middle Cebolla Creek Tuff contains basal surge beds, overlain by vitrophyre of uniform mafic dacite that becomes less welded upward. Uppermost Nelson Mountain Tuff consists of nonwelded to weakly welded, crystal-poor rhyolite, which grades upward to a densely welded caprock of crystal-rich dacite (~68% SiO2). White arrows show contacts between outflow units. 2006 U.S. Department of the Interior U.S. Geological Survey CONTENTS Geologic setting . 1 Volcanism . 1 Structure . 2 Methods of study . 3 Description of map units . 4 Surficial deposits . 4 Glacial deposits . 4 Postcaldera volcanic rocks . 4 Hinsdale Formation . 4 Los Pinos Formation . 5 Oligocene volcanic rocks . 5 Rocks of the Creede Caldera cycle . 5 Creede Formation . 5 Fisher Dacite . 5 Snowshoe Mountain Tuff . 6 Rocks of the San Luis caldera complex . 7 Rocks of the Nelson Mountain caldera cycle . 7 Rocks of the Cebolla Creek caldera cycle . 9 Rocks of the Rat Creek caldera cycle . 10 Lava flows premonitory(?) to San Luis caldera complex . .11 Rocks of the South River caldera cycle . -
Oil, Natural Gas and Helium Potential of the Chupadera Mesa Area, Lincoln and Socorro Counties, New Mexico
Oil, natural gas and helium potential of the Chupadera Mesa area, Lincoln and Socorro Counties, New Mexico by Ronald F. Broadhead and Glen Jones February 27, 2004 New Mexico Bureau of Geology and Mineral Resources A division of New Mexico Institute of Mining and Technology Socorro, NM 87801 Oil, natural gas and helium potential of the Chupadera Mesa area, Lincoln and Socorro Counties, New Mexico By Ronald F. Broadhead1 and Glen Jones2 1 Principal Petroleum Geologist and 2 Assistant Director for Computer/Internet Services New Mexico Bureau of Geology and Mineral Resources, a division of New Mexico Institute of Mining and Technology, Socorro, NM 87801 ABSTRACT The Chupadera Mesa region encompasses 3900 mi2 in eastern Socorro and western Lincoln Counties, central New Mexico. The area includes varied geological elements including the broad Jornada del Muerto Basin in the west, and the Oscura Mountains and Chupadera Mesa in the medial area. The Laramide-age Sierra Blanca Basin and several isolated mountain ranges formed principally by Tertiary-age igneous intrusive bodies occupy the eastern third of the region. The Chupadera Mesa area has been sparsely drilled. A total of 45 wells have been drilled within the project area. This is a density of approximately one well for every 85 mi2. Many of the wells are shallow and reached total depth in Permian strata. Only 20 wells have been drilled to Precambrian basement. This is a density of one well per 200 mi2, or 6.4 townships. Neither oil, natural gas nor helium production have been established. Nevertheless, several of the wells have encountered promising shows of oil, natural gas, and helium. -

Coal Fields of Northwestern Colorado and Northeastern Utah
COAL FIELDS OF NORTHWESTERN COLORADO AND NORTHEASTERN UTAH. By HOYT S. GALE. INTRODUCTION. NATURE OF THE PRESENT INVESTIGATION. This paper is a preliminary statement of the results of work in the coal fields of northwestern Colorado and northeastern Utah during the summer of 1907.° In 1905 a preliminary reconnaissance of the Yampa coal field, of Routt County, was made.6 In the summer of 1906 similar work was extended southwestward from the Yampa field, and the Danforth Hills and Grand Hogback coal fields, of Routt, Rio Blanco, and Garfield counties, were mapped.6 The work of the past season was a continuation of that of the two preceding years, extend ing the area studied westward through Routt and Rio Blanco counties, Colo., and including some less extensive coal fields in^Uinta County, Utah, and southern Uinta County, Wyo. ACCESSIBILITY. At present these fields have no_ railroad connection, although surveys for several projected lines have recently been made into the region. Of these lines, the Denver, Northwestern and Pacific Railway ("Moffat road") is under active construction in .the eastern part of Routt County and bids fair to push westward not far from the lower Yampa and White River fields in the near future. An extension of the Uintah Railway has been surveyed from Dragon to Vernal, Utah, crossing the projected route of the "MofFat road" near Green River. The Union Pacific Railroad has made a preliminary survey south from Rawlins, Wyo., intending to reach the Yampa Valley in the vicinity of Craig. a A more complete report combining the results of the preceding season's work in the Danforth Hills and Grand Hogback fields with those of last season's work as outlined here, together with detailed contour maps of the whole area, will be published as a (separate bulletin of the Survey. -
Cliff Palace Teacher Resource
Teacher Resource Set Title Cliff Palace, Mesa Verde National Park Developed by Laura Douglas, Education ala Carte Grade Level 3 – 4 Essential Questions How can primary sources help us learn about the past and how the people lived at Cliff Palace in what is now Mesa Verde National Park? What natural resources were used by the Ancestral Puebloan people that lived at Cliff Palace? How did the natural environment effect the way in which Ancestral Puebloan built their shelters? Why did the Ancestral Puebloan people migrate from Cliff Palace? Contextual Paragraph Mesa Verde National Park is located in Montezuma County, Colorado in the southwestern corner of the state. As of its nomination to the National Register of Historic Places in 1978 it had more than 800 archaeological sites recorded or in the process of inventory. Today there are nearly 5,000 documented sites including about 600 cliff dwellings. Mesa Verde, which means, “green table” was inhabited by Ancestral Puebloans, a branch of the San Juan Anasazi Indians, from about 580 CE to 1300 CE. Today it is the most extensive and well-developed example of prehistoric cliff dwellings. For in depth information about Mesa Verde National Park visit the Colorado Encyclopedia at: https://coloradoencyclopedia.org/article/mesa-verde-national-park. Archaeologists have identified distinct periods during Mesa Verde’s habitation based on artifacts and ruins discovered there. The Cliff Palace was constructed during the Pueblo III period. According to dendrochronology (tree-ring dating), Cliff Palace construction and refurbishment happened from 1190 CE – 1260 CE, although most was done during a 20- year span.
