This study considers the temporal and spatial distribution of Steller's Eiders (Polysticta stelleri) during molt along the north side of the Alaska Peninsula from Port Heiden to Bechevin Bay. Subadult eiders molted primarily at Nelson Lagoon, adult males at Nelson Lagoon and Izembek Bay, and adult females primarily at Izembek...

The standard thermodynamic properties of phases in the lime‐alumina‐silica‐ water system between 273.15 and 1800 K at 101.325 kPa (1 atm) were evalated from published experimental data. Phases included in the compilation are boehmite, diaspore, gibbsite, kaolinite, dickite, halloysite, andalusite, kyanite, sillimanite, Ca‐Al cliniopyroxene, anorthite, gehlenite, grossular, prehnite, zoisite, margarite,...

A reconnaissance geochemical stream-sediment sampling survey was conducted in a 1,150-km2 (440 mi2) area in the central part of the Okanogan Range, adjacent on the west to a 2,000-km2 (800 mi2) area previously studied. About 75 percent of the bedrock is composed of a mosaic of elongate northwest-trending Mesozoic plutons,...

The alluvial valley of the North Fork Solomon River is an important agricultural area. Reservoir releases diverted below Kirwin Dam are the principal source of irrigation water. During the 1970'S, severe water shortages occurred in Kirwin Reservoir and other nearby reservoirs as a result of an extended drought. Some evidence...

Uranium in the Marysvale volcanic field is known to occur in several geologic environments and is thought to occur in others. These known and hypothetical occurrences are of various kinds, ranging in derivation from rhyolite magma, through porphyry-type deposits, hydrothermal vein deposits, dispersed hydrothermal deposits, and, after secondary transport in...

We have taken advantage of the recent increase in strong-motion data at close distances to derive new attenuation relations for peak horizontal acceleration and velocity. This new analysis uses a magnitude-independent shape, based on geometrical spreading and anelastic attenuation, for the attenuation curve. An innovation in technique is introduced that...

A 2.1-m core from Laguna de las Trancas, a marsh atop a landslide in northern Santa Cruz County, California, has yielded a pollen record for the period between about 30,000 B. P. and roughly 5000 B. P. Three pollen zones are recognized. The earliest is characterized by high frequencies of...

Sands of Miocene, Pliocene(?), and Pleistocene age contain fresh-water in central Rapides Parish, La. In this area the base of fresh ground water ranges from 900 feet to more than 2,500 feet below National Geodetic Vertical Datum of 1929. The principal sources of water are the Carnahan Bayou, Williamson Creek,...

Sulfate is known to be an active oxidizing agent at high temperatures; however, both experimental and geologic evidence indicate that as a hydrothermal solution cools (to about 200 degrees C, depending on pH) kinetic factors slow the rate at which sulfate enters into redox reactions. This retardation of sulfate reduction...

The Antlers aquifer, which consists of as much as 900 feet of friable sandstone, silt, clay, and shale, crops out in an area of 1,860 square miles and underlies about 4,400 square miles in southeastern Oklahoma. Precipitation ranges from 35 to 50 inches per year across the outcrop area, which...

The Rincon and Mesilla Valleys of New Mexico extend from Caballo Reservoir to El Paso del Norte, west of El Paso, Texas. Water supplies for this area are obtained from the Rio Grande and from the saturated sediments filling the intermontane basins of south-central New Mexico.The two major aquifers are...

The upper Virgin River and Kanab Creek basins area occupies parts of Iron, Kane, and Washington Counties in south-central Utah. It includes about 1,300 square miles (3,370 square kilometers) in the upper Virgin River basin and about 650 square miles (1,680 square kilometers) in the upper Kanab Creek basin. The...
