Charles W. Mase, S.P. Galanis, Robert J. Munroe
1979, Open-File Report 79-1136
With the exception of values from one borehole drilled at Palm Spring and three boreholes drilled around Saline Valley dry lake, eight new heat-flow values in Saline Valley, California, are within or somewhat below the range one would expect for this region of the Basin and Range heat-flow province. The...

Effects of uranium development on erosion and associated sedimentation in southern San Juan Basin, New Mexico
Maurice E. Cooley
1979, Open-File Report 79-1496
A reconnaissance was made of some of the effects of uranium development on erosion and associated sedimentation in the southern San Juan Basin, where uranium development is concentrated. In general, the effects of exploration on erosion are minor, although erosion may be accelerated by the building of access roads, by...

During gas and oil exploration efforts in the Washakie Basin in Sweetwater County, Wyoming, undertaken by Ladd Petroleum Co. (a subsidiary of Utah International Inc.) core from the Upper Cretaceous Almond Formation of the Mesaverde Group was collected from their 1-22 Federal well. (See figure 1 for location.) From this...
Magnitude and frequency of floods in western Oregon
David Dell Harris, Larry L. Hubbard, Lawrence E. Hubbard
1979, Open-File Report 79-553
A method for estimating the magnitude and frequency of floods is presented for unregulated streams in western Oregon. Equations relating flood magnitude to basin characteristics were developed for exceedance probabilities of 0.5 to 0.01 (2- to 100-year recurrence intervals). Separate equations are presented for four regions: Coast, Willamette, Rogue-Umpqua, and...
Hydrologic data for wells, springs, and streams in Boulder County, Colorado
Dennis C. Hall, Elaine L. Boyd, Doug Cain
1979, Open-File Report 79-979
Hydrologic data collected in 1975-77 as part of a comprehensive water-resources investigation of Boulder County, Colo., by the U.S. Geological Survey in cooperation with the Boulder County Health Department and the Colorado Geological Survey are presented in this report. The data, in tabular and graphic form, consist of water-quality analyses...
Titaniferous magnetite in the layered intrusive complex at Lakathah, Kingdom of Saudi Arabia
Conrad Martin, Ralph Jackson Roberts, D. B. Stoeser
1979, Open-File Report 79-1210
The Lakathah layered intrusive complex about 90 km east of Qunfudhah contains significant resources of low-grade titanium-bearing rock. The complex is about 10 km in diameter and consists of three principal units: an outer syenite ring, an intermediate diorite-gabbro zone, and a central pyroxenite-hornblendite core. The principal mineralization zone is...

Hydrogeologic features of the alluvial deposits in the Nowood River drainage area, Bighorn Basin, Wyoming
M. E. Cooley, William J. Head
1979, Open-File Report 79-1291
In the Nowood River drainage area, Wyoming, the principal deposits comprising the alluvial aquifer include the flood-plain and younger (generally undissected) alluvial-fan deposits and a unique boulder-fan gravel. Other deposits mapped, but virtually nonwater yielding, are the older (dissected) alluvial-fan, pediment, and terrace deposits. Terraces are capped by gravel and...

Water budget and mathematical model of the Coconino Aquifer, southern Navajo County, Arizona
Larry J. Mann
1979, Open-File Report 79-348
The main source of water in the 3,400-square-mile area of southern Navajo County is the large volume of ground water in storage in the Coconino aquifer, which consists of the Coconino Sandstone, the uppermost part of the underlying Supai Formation, and the overlying Kaibab Limestone. The amount of water withdrawn...
Water-level predictions for Indian Wells Valley ground-water basin, California, 1978
Michael J. Mallory
1979, Open-File Report 79-254
Ground-water pumpage in Indian Wells Valley, virtually a closed basin in the Mojave Desert of southern California, has increased gradually since 1945 and presently exceeds the long-term mean annual recharge (perennial supply). In order to aid in the understanding and management of the ground-water basin, a digital ground-water model was...
Chemical analyses of ground water related to geothermal investigations in the Teton River area, eastern Idaho
E. G. Crosthwaite
1979, Open-File Report 79-687
Water samples were collected from 31 wells and springs in eastern Idaho and western Wyoming to help evaluate the potential geothermal resources in the Teton River area, Idaho. The water analyses included the common anions and cations, oxygen-18, deuterium, and several minor elements. Actual temperatures of the sampled thermal waters...

Techniques used for the cleaning, concentration, and observation of chrysomonad cysts from sediments
Albert D. Mahood, David P. Adam
1979, Open-File Report 79-1431
This report documents the techniques that we use to clean and concentrate chrysomonad cysts prior to examining them under a scanning electron microscope. Like diatoms, chrysomonad cysts are composed of opaline silica; the method we use is basically the same as one of the methods commonly used to prepare diatoms....
Two oil types on the North Slope of Alaska: implications for future exploration
Leslie B. Magoon, George Edwin Claypool
1979, Open-File Report 79-1649
Forty oil samples from across the North Slope of Alaska have been analyzed by the U.S. Bureau of Mines and the U.S. Geological Survey. Results of these analyses suggest two separate genetic oil types. The first type, the Simpson-Umiat oil type, occurs in reservoir rocks of Cretaceous and Quaternary age...
