SMITH 1Nevada Bureau of Mines and Geology, University of Nevada, Mail Stop 178, Reno, NV 89557 2Department of Geology, University of Iowa, Iowa City, IA 52242 *Now at Exxon Mobil Development Company, 16825 Northchase Drive, Houston, TX 77060 3Department of Geology, Vanderbilt University, Nashville, TN 37235 4Department of Geoscience, University of Nevada, Las Vegas, NV 89154 ABSTRACT The northern Colorado River extensional corridor is a 70- to 100-km-wide region of moderately to highly extended crust along the eastern margin of the Basin and Range province in southern Nevada and northwestern Arizona. It has occupied a criti- cal structural position in the western Cordillera since Mesozoic time. In the Cretaceous through early Tertiary, it stood just east and north of major fold and thrust belts and also marked the northern end of a broad, gently (~15o) north-plunging uplift (Kingman arch) that extended southeastward through much of central Arizona. Mesozoic and Paleozoic strata were stripped from the arch by northeast-flowing streams. Peraluminous 65 to 73 Ma granites were emplaced at depths of at least 10 km and exposed in the core of the arch by earliest Miocene time. Calc-alkaline magmatism swept northward through the northern Colorado River extensional corridor during early to middle Miocene time, beginning at ~22 Ma in the south and ~12 Ma in the north. -

Duebendorfer, Ph.D. Graduate Faculty Representaf , Donna E.Weistrop, Ph.D. Dean of the Graduate College, Ronald W. Smith, Ph.D. University of Nevada, Las Vegas December, 1993 ii Abstract The Tuff of Bridge Spring (TBS) is a regionally-widespread, andesite to rhyolite (59 .50 to 74.91 wt. %) ash-flow tuff of mid-Miocene age (ca. 15.2 Ma) that is exposed in the northern Colorado River extensional corridor of southern Nevada and northwestern Arizona. Determination of the areal distribution, geochronology, lithology, geochemistry, and internal stratigraphy of the TBS is important for its establishment as a reliable stratigraphic reference horizon for tectonic reconstructions of the extensional corridor during the middle Miocene. -

Birds AMERICAN PEREGRINE FALCON Falco peregrinus anatum Covered Species Family Falconidae (Falcon Family) Gerald & Buff Corsi/CalPhoto Gerald & Buff Description: The American peregrine falcon is a medium-sized raptor, total length 41 - 51 cm (16 - 20 in.). Adults have a dark gray back and crown, dark bars or streaks on a pale chest and abdomen, and heavy malar (cheek) stripes on the face. Young birds, prior to first molt, are brownish above and underparts streaked vertically with brown. Nesting season from March to June; clutch size 3 - 4 eggs; incubation approximately 33 days; only 2 - 3 chicks hatch and fledge 42 days later. Diet: Peregrines prey almost exclusively on medium-sized birds (pigeons, doves, ducks, swifts, and others), and occasionally on bats. It hunts for its food by diving after the prey and catching it mid-air. Habitat: Peregrines inhabit mixed conifer, pinyon-juniper, sagebrush, lowland riparian, and grassland habitats, as well as agricultural and urban areas. Nests are shallow hollows in soil, rock ledges, small caves on high cliffs, old raptor nests, or tree cavities. These falcons also are known to nest on various man-made structures within the Las Vegas Valley. Range: Known throughout the southern half of North America. In Clark County, Nevada, known from the Spring Mountains, Desert National Wildlife Range, Logandale, Overton State Wildlife Management Area, and Newberry Mountains. Known to nest in the Black Mountains, Lake Mead area, and within the Las Vegas Valley area. Special Remarks: The American peregrine falcon was removed from the Federal list of endangered species on August 25, 1999; the species will be monitored for at least 13 years. -

A COMPILATION OF THE GEOLOGY AND HYDROLOGY OF THE BLACK MOUNTAINS-BULLHEAD CITY AREA, ARIZONA by Raymond C. Harris Arizona Geological Survey Open-File Report 98-26 December, 1998 Arizona Geological Survey _ 416 W. Congress, Suite #100, Tucson, Arizona 85701 (Includes 40 pages text) Produced in cooperation with the US Geological Survey This report is preliminary and has not been edited or reviewed for confonnity with Arizona Geological Survey standards A COMPILATION OF THE GEOLOGY AND HYDROLOGY OF THE BLACK MOUNTAINS-BULLHEAD CITY ARE~ ARIZONA INTRODUCTION This report presents a compilation of geologic and hydrologic information for the Bullhead City-Black Mountains area of we stem Arizona. The purpose of the project is to determine the significance of mining, geology, and geohydrology in the chemistry of Bullhead City area groundwater. Mining in the Black Mountains has taken place since the 1800s, and the region provides a good opportunity to investigate any links between mining and water quality. The study encompasses the area from the crest of the Black Mountains on the east, the Colorado River on the west, latitude 35 0 on the south and the top of township 2IN at the north (Figure 1). Information was compiled from published and unpublished sources including U.S. Bureau of Land Management, U.S. Geological Survey, U.S. Bureau of Mines, U.S. Natural Resources Conservation Service (Department of Agriculture), Arizona Geological Survey, Arizona State Land Department, Arizona Department of Water Resources, and Arizona Department of Environmental Quality. LAND STATUS AND LAND USE Land ownership in the Black Mountains-Bullhead City area includes State, Federal, Indian Reservation, and private lands. -

Cenozoic Evolution of the Abrupt Colorado Plateau–Basin And
The Geological Society of America Field Guide 11 2008 Cenozoic evolution of the abrupt Colorado Plateau–Basin and Range boundary, northwest Arizona: A tale of three basins, immense lacustrine-evaporite deposits, and the nascent Colorado River James E. Faulds* Nevada Bureau of Mines and Geology, MS 178, University of Nevada, Reno, Nevada 89557, USA Keith A. Howard* U.S. Geological Survey, MS 973, Menlo Park, California 94025, USA Ernest M. Duebendorfer* Department of Geology, Northern Arizona University, Flagstaff, Arizona 86011, USA ABSTRACT In northwest Arizona, the relatively unextended Colorado Plateau gives way abruptly to the highly extended Colorado River extensional corridor within the Basin and Range province along a system of major west-dipping normal faults, including the Grand Wash fault zone and South Virgin–White Hills detachment fault. Large growth-fault basins developed in the hanging walls of these faults. Lowering of base level in the corridor facilitated development of the Colorado River and Grand Can- yon. This trip explores stratigraphic constraints on the timing of deformation and paleogeographic evolution of the region. Highlights include growth-fault relations that constrain the timing of structural demarcation between the Colorado Plateau and Basin and Range, major fault zones, synextensional megabreccia deposits, non- marine carbonate and halite deposits that immediately predate arrival of the Colo- rado River, and a basalt fl ow interbedded with Colorado River sediments. Structural and stratigraphic relations indicate that the current physiography of the Colorado Plateau–Basin and Range boundary in northwest Arizona began developing ca. 16 Ma, was essentially established by 13 Ma, and has changed little since ca. -
