A Miocene Flora From Grand Coulee, Washington

Description: From introduction: The fossil plants described in the present report were collected at the north end of Grand Coulee during the summer of 1927 by Messrs. T. A. Bonser, F. A. Roberts, and Walter Bruce, of Spokane, and F. W. McCann, of Coulee City. The locality is in the big bend of the Columbia River near the northern boundary of Grant County, Wash., about 85 miles west of the plant-bearing Latah sediments around Spokane. The outcrop in Grand Coulee is about the same distance east of the crest of the Cascade Mountains, about 100 miles northeast of the plant beds at Ellensburg, which are of approximately the same age, and some 200 miles west of beds in Idaho yielding a similar flora and assigned to the Payette formation by Knowlton and others.

Preliminary Report on Uranium and Thorium Content of Intrusive Rocks in Northeastern Washington and Northern Idaho

Description: From summary: The purpose of this study was to delineate favorable areas for uranium resources in northeastern Washington and northern Idaho by identifying granitic rocks with relatively large amounts of uranium and (or) thorium. Results are based on analyses of 344 rock samples; 230 were collected during this study, and data for the rest were taken from previous publications.

Preliminary Report of Reconnaissance for Uraniferous Granitic Rocks in Montana, Idaho, Oregon, Washington, and California

Description: From abstract: A reconnaissance to determine the uranium content of granitic rocks in the western states was made during parts of October and November 1951. The paucity of our knowledge of the granitic rocks that are most likely to contain significant quantities of uranium has prevented all but a very general isolation of areas or types of granitic rocks for reconnaissance examination.

Approximate Quantitative Microscopy of Pulverized Ores, Including the Use of the Camera Lucida

Description: Technical paper issued by the Bureau of Mines over microscopy of pulverized ores. As stated in the introduction, "this paper, which deals with the study of pulverized ores and the use of the camera lucida in such work, discusses an investigation undertaken at the Seattle and the Golden mining experiment stations of the Bureau of Mines" (p. 3). This paper includes tables, illustrations, and photographs.

Surficial Geology of Mount Rainier National Park, Washington

Description: From introduction: Much of the ground surface around Mount Rainier volcano is directly underlain by loose geologic deposits that veneer the hard rock formations. Examples of these deposits are sand and gravel bars along the rivers, ridges of loose rock debris beside the glaciers, and sloping aprons of rock fragments beneath almost every cliff. Even though they are generally thin and inconspicuous when compared with the rock formations, these surficial deposits are clues to geologic events that. have profoundly influenced the shape of the park's landscape. Thus, from the character and extent of glacial deposits one can judge the age and size of former glaciers that carved the cirques and deep canyons of the park; from the mudflows which streamed down nearly every valley one can infer the age and size of huge landslides of the past that helped determine Mount Rainier's present shape; and from the pumice deposits some of the volcano's recent eruptive activity can be reconstructed.

Geologic Study of Kettle Dome, Northeast Washington: Final Report

Description: From abstract: This geologic study of Kettle dome, northeast Washington, encompasses an area of approximately 800 square miles (2048 sq km). The evaluation of uranium occurrences associated with the igneous and metamorphic rocks of the dome and the determination of the relationship between uranium mineralization and stratigraphic, structural, and metamorphic features of the dome are the principal objectives. Evaluation of the validity of a gneiss dome model is a specific objective. The principal sources of data are detailed geologic mapping, surface radiometric surveys, and chemical analyses of rock samples.

Analyses of Washington Coals: Supplement to Technical Papers 491 and 618

Description: From Washington Coalfields: The geographical distribution of the principal coal areas of Washington is shown in figure 1. Detailed information concerning these fields is given in Bureau of Mines Technical Paper 491. Further information on the minor coal areas is given in two bulletins of the Washington Division of Mines and Geology. Analyses, plastic properties, free-swelling indexes, and agglutinating values of the separate coals, together with data on yields of carbonization products and properties of the cokes produced in laboratory tests and under operating conditions."

Carbonizing Properties: British Columbia, Matanuska Valley (Alaska), and Washington Coals and Blends of Six of Them with Lower Sunnyside (Utah) Coals

Description: From Introduction and Summary: "This report gives results of an investigation of the carbonizing properties of 18 coals, including 2 from Alaska, 12 from British Columbia, 3 from Washington, and 1 from Utah. Each coal was carbonized in the standard 13-inch Bureau of Mines-American Gas Association (BM-AGA) retort at 900 degrees C."

Midnite Mine Summary Report

Description: The Midni'e Mine is an inactive, hard-rock uranium mine in Stevens County, WA. Oxidation of sulfide-containing minerals in the ore body produces large quantities of acidic water. The U.S. Bureau of Mines was directed by Congress in Fiscal Year 1994 to perform technological research on the treatment of radioactive water and disposal of treatment residues at the Midnite Mine and en overall site reclamation. This Report of Investigations summarizes the studies that were completed on: 1) treatment alternatives for uranium contaminated acid mine drainage, and 2) overall site reclamation, including: ground water flowpaths in the bedrock, radiation, and waste rock reactivity. As an aid to site reclamation, a Geographic Information System database was also produced that contains available current and historic data and information on the Midnite Mine. This report explains the scope of the Bureau's study and summarizes the results of its investigations.

The second part of the report discusses in detail the relationship between between meteorological conditions in the valley and atmospheric diffusion processes. The third part gives the provisional operating regimes in force during the investigation, the amount of sulfur fixed and amount emitted to the atmosphere, and summary of data from the permanent recorders."

Impact of Changes in Land Use on the Ground-Water System in the Sequim-Dungeness Peninsula, Clallam County, Washington

Description: From purpose and scope: In 1978, the U.S. Geological Survey, in cooperation with the State of Washington Department of Ecology and the Board of Clallum County Commissioners, began a study that would (1) make a general assessment of the water resources of the developed area of the county, (2) identify present and potential water-resource problems in these areas, and (3) make in-depth analyses of selected problem areas. The first two items have been completed and documented in a forthcoming report by Drost.

Water Resources of Clallam County, Washington: Phase 1 Report

Description: From purpose and scope: The objectives of this study are (1) inventory the existing surface- and ground-water supplies of the county, and assess their quantity and quality; (2) determine the effects of irrigation on ground-water recharge in a northeastern part of the county (Sequim area); and (3) identify present and potential sources of contamination of the county's water resources and to determine if these present or potential contaminants will affect the quality of availability of water.
