Wayne A. Van Voast, L.A. Jerabek, R.P. Novitzki
1970, Hydrologic Atlas 345
The Redwood River watershed contains 739 square miles underlain by glacial drift and sedimentary and crystalline rocks. The land surface slopes gently northeastward and eastward from altitudes greater than 1900 feet at the southwestern edge to less than 850 feet at the mouth of the Redwood River in the east. The...
Morphology, sedimentation, and seismic characteristics of an arctic beach, Nome, Alaska - with economic significances
H. Gary Greene
1970, Open-File Report 70-142
Arctic beaches exhibit characteristics that do not occur on beaches in more temperate zones. In the summer of 1967 morphological, sedimentological, and seismic refraction studies were made on an arctic beach near Nome, Alaska, in order to better define these distinguishing characteristics.Several distinct microrelief structures are developed during ice break-up...
Paleozoic and Precambrian rocks of Alaska and their role in its structural evolution
Michael Churkin Jr.
1970, Open-File Report 70-64
Acknowledging that there are large gaps in the knowledge of the geology of Alaska, the following threefold subdivision of Alaska into Paleozoic tectonic elements is proposed: Southern Alaska--the Alaska Range and farther south--is the northern end of the Paleozoic Cordilleran geosyncline that rims the eastern Pacific. Northern Alaska--the northeastern Brooks...

The Valentine Formation of A. L. Lugn, which is of late Miocene and early Pliocene age, contains diatomaceous and plant-bearing sediments at a locality on the north bluff of the Niobrara River, about 10 miles south of Kilgore, Cherry County, Nebr. The fossil flora has been studied by H. D....
Hydrologic effects of floodwater-retarding structures on Garza-Little Elm Reservoir, Texas
Clarence R. Gilbert, Stanley P. Sauer
1970, Water Supply Paper 1984
The Texas District of the Water Resources Division of the U.S. Geological Survey has collected and analyzed hydrologic data since 1953 to define the effects of systems of floodwater-retarding structures on downstream water and sediment yield. The district project includes 11 study areas ranging from 18 to 80 square miles...
Common marsh plants of the United States and Canada
Neil Hotchkiss
1970, Resource Publication 93
This is the fourth of a series of publications on field identification of North American marsh and water plants. It describes the emergent and semiemergent plants most likely to be found in inland and coastal marshes. It omits hundreds of uncommon marsh plants and plants less characteristic of marshes than...

Water resources of Racine and Kenosha Counties, southeastern Wisconsin
R. D. Hutchinson
1970, Water Supply Paper 1878
Urbanization and changes in regional development in Racine and Kenosha Counties are increasing the need for water-resources information useful for planning and management. The area is fortunate in having abundant supplies of generally good quality water available for present and projected future needs. Lake Michigan and ground-water reservoirs have great...
Water resources of the River Rouge basin, southeastern Michigan
R. L. Knutilla
1970, Hydrologic Atlas 356
The River Rouge basin is characterized by moderately hilly topography to the northwest graduating to a relatively level land surface to the south east.Stream gradients near the northwestern basin divide are relatively steep; but many become more steep in reaches where they cross beach lines of former glacial lakes. In...
Sediment transport by streams in the Palouse River basin, Washington and Idaho, July 1961-June 1965
P. R. Boucher
1970, Water Supply Paper 1899-C
The Palouse River basin covers about 3,300 square miles in southeastern Washington and northwestern Idaho. The eastern part of the basin is composed of steptoes and foothills which are generally above an altitude of 2,600 feet; the central part is of moderate local relief and is mantled chiefly by thick...
Floods in the upper Des Moines River Basin, Iowa
Harlan H. Schwab
1970, Open-File Report 70-296
Data on flood stages, discharges, and frequency are used in the design of bridges and other structures and the conduct of various operations on the flood plains of streams. This report provides these data in the form of flood-peak records, gaging-station records, frequency curves, and flood profiles. Information is provided...
Summary of floods in the United States during 1964
J.O. Rostvedt
1970, Water Supply Paper 1840-C
This report describes the most outstanding floods in the United States during 1984. The four most damaging floods during the year were in December in the Far Western States, in March along the Ohio River, in September in central and northern Florida and southern Georgia, and in June in northwestern...

Feasibility of surveying pesticide coverage with airborne fluorometer
George Eimert Stoertz, William R. Hemphill
1970, Open-File Report 70-315
Response of a Fraunhofer line discriminator (FLD) to varying distributions of granulated corncobs stained with varying concentrations of Rhodamine WT dye was tested on the ground and from an H-19 helicopter. By design the instrument detected fluorescence specifically at the sodium D2 Fraunhofer line (5890 angstroms). The granules are used...
Correlation of aeromagnetics and aeroradioactivity with lithology in the Spotsylvania area, Virginia
S.K. Neuschel
1970, Geological Society of America Bulletin (81) 3575-3582
The U.S. Geological Survey made a detailed aeromagnetic and aeroradioactivity survey of 1050 sq mi of the Spotsylvania area in the Piedmont province of eastern Virginia. The study area consists of sixteen 7 1/2-minute quadrangles in Spotsylvania and adjoining counties, Virginia. East-west traverses were flown at a spacing of 1/2...
A revision of stratigraphic nomenclature for middle precambrian rocks in Northern Michigan
W.F. Cannon, J. E. Gair
1970, Geological Society of America Bulletin (81) 2843-2846
The name Marquette Range Supergroup is proposed to supplant the term Animikie Series for middle Precambrian strata of the Northern Peninsula of Michigan and adjacent areas of Wisconsin. The Marquette Range Supergroup consists of the Chocolay, Menominee, Baraga, and Paint River Groups, as defined in previous literature. We feel that...

Michael Churkin Jr., Claire Carter, George Donald Eberlein
1970, Journal of the Geological Society (126) 319-330
The first discovery in North America of a succession of graptolite faunas across the Ordovician–Silurian boundary has been made on Esquibel Island, in south-eastern Alaska, where five graptolite zones are represented in an 18 m interval of shale in the Descon Formation. Despite the thinness of...
Radiometric ages and stratigraphic sequence of volcanic and plutonic rocks, southern Nye and western Lincoln Counties, Nevada
Richard F. Marvin, F.M. Byers Jr., Harald H. Mehnert, Paul P. Orkild, T. W. Stern
1970, Bulletin of the Geological Society of America (81) 2657-2676
The geochronology of Tertiary igneous events at the Nevada Test Site and adjacent area is outlined by 36 recently determined K-Ar ages, together with other published K-Ar ages. The first evidence of Tertiary igneous activity is the ash-fall bedded tuffs in the Horse Spring Formation. One such tuff has been...
A re-evaluation of basalt-obsidian relations at East Lake Fissure, Newberry Caldera, Oregon
Michael W. Higgins, Aaron C. Waters
1970, Bulletin of the Geological Society of America (81) 2835-2842
Andesite scoria, agglutinate, and small flows formed by thin lava gushes that erupted from East Lake Fissure on the north wall of Newberry Caldera carry numerous inclusions of platy rhyolite, partly melted platy rhyolite, and frothy obsidian. This association of obsidian and “basalt” has been...
Geochronology of Tertiary igneous rocks in central Nevada
Edwin H. McKee, Miles L. Silberman
1970, Bulletin of the Geological Society of America (81) 2317-2327
Potassium-argon dating of Tertiary igneous rocks in Lander County, central Nevada, indicates that igneous activity was episodic and can be separated into three periods. Igneous activity started abruptly about 37 m.y. ago with local extrusion of andesitic to quartz-latitic lava flows and intrusion of hypabyssal rocks of similar composition. This...
Deuterium content of snow cores from Sierra Nevada area
I. Friedman, G.I. Smith
1970, Science (169) 467-470
The relative deuterium content was measured on 37 snow cores collected in April 1969 in the Sierra Nevada. The deuterium content varies inversely with altitude of collection (approximately 40 per mil per 1000 meters) but is unrelated to latitude. The altitude relationship is particularly well defined west of the crest...
