Water resources of the Yellow Medicine River Watershed, Southwestern Minnesota
R.P. Novitzki, Wayne A. Van Voast, L.A. Jerabek
1969, Hydrologic Atlas 320
Glacial drift and Cretaceous sedimentary rocks are the major aquifers in the Yellow Medicine River watershed unit. The Yellow Medicine and Minnesota Rivers are the major sources of surface water. For physiographic regions – Upland Plain, Slope, Lowland Plain, and Minnesota River Flood Plain – influence surface drainage, and the flow...
Cretaceous sedimentation and tectonism in the southeastern Kaiparowits region, Utah
Fred Peterson
1969, Open-File Report 69-202
Upper Cretaceous strata in the southeastern Kaiparowits region of south-central Utah consist of approximately 3,500 feet of interfingering sandstone, mudstone, shale, and coal in the Dakota Formation (oldest), Tropic Shale, Straight Cliffs Formation, and Wahweap Formation (youngest). The formations consist of several depositional facies that can be recognized by characteristic...
Water resources of the Pine River Basin, southeastern Michigan
R. L. Knutilla
1969, Hydrologic Atlas 327
The land surface of the Pine River basin, an area of 194 square miles, is a relatively flat or gently undulating northwest to southeast trending glacial lake plain.The plain is interrupted by small streams and by a series of former glacial lake beaches. Other irregularities are the morainal hills in...
Ground-water resources of the St. James area, South-central Minnesota
L.H. Ropes
1969, Hydrologic Atlas 334
The purpose of this investigation was to evaluate the quality and quantity of the ground-water resources in the area of St. James, Minnesota. St. James is located in the center of Watonwan County in south-central Minnesota. The area is covered by a thick layer of glacial drift which is underlain...
Water resources of the Belle River basin, southeastern Michigan
R. L. Knutilla
1969, Hydrologic Atlas 317
This hydrologic atlas represents a part of a comprehensive study of the water resources of southeastern Michigan. The purpose of the atlas is to present data on (1) the physical features of the Belle River and its tributaries, (2) the characteristics of streamflow, (3) the quality of ground and surface...
Optical method for determining particle sizes of coarse sediment
John R. Ritter, Edward J. Helley
1969, Techniques of Water-Resources Investigations 05-C3
A particle-size analyzer was used to determine particle sizes of sediment by an optical technique based on an adjustable circle of light which determines the intermediate axis of the sediment particles shown on a photograph. Data from counting particles in various size ranges can be presented either in the form...
Estuarine studies in upper Grays Harbor, Washington
Joseph P. Beverage, Milton N. Swecker
1969, Water Supply Paper 1873-B
Improved management of the water resources of Grays Harbor, Wash., requires more data on the water quality of the harbor and a better understanding of the influences of industrial and domestic wastes on the local fisheries resources. To provide a more comprehensive understanding of these influences, the U.S. Geological Survey...
Establishment of gold-quartz standard GQS-1
Hugh T. Millard, John Marinenko, John E. McLane
1969, Circular 598
A homogeneous gold-quartz standard, GQS-1, was prepared from a heterogeneous gold-bearing quartz by chemical treatment. The concentration of gold in GQS-1 was determined by both instrumental neutron activation analysis and radioisotope dilution analysis to be 2.61?0.10 parts per million. Analysis of 10 samples of the standard by both instrumental neutron...
