Chemical and biological conditions in Bald Eagle Creek and prognosis of trophic characteristics of Foster Joseph Sayers Reservoir, Centre County, Pennsylvania
Herbert N. Flippo Jr.
1970, Open-File Report 71-109
Foster Joseph Sayers. Reservoir will b.e impounded on moderately fertile soils; however, its water source, Bald Eagle Creek, is a bicarbonate-water stream that is over~y-enriched with nutrients. About 650 of the 1,730 acres to be inundated in summer are subject to infestation with aquatic weeds. Nuisance algal "blooms" are expected...

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...
Geologic map of the Arvada quadrangle, Colorado
Robert M. Lindvall
1970, Open-File Report 70-198
Many of the engineering-geologic problems in the Arvada quadrangle are related to the unconsolidated surficial deposits, which mantle the bedrock to depths of as much as 40 or 50 feet. In this report most of the emphasis is placed on the map distribution of these materials and on a description...
Various aspects of uranium ore rolls in the United States
Elbert Nelson Harshman
1970, Open-File Report 70-154
About 40 percent of the uranium ore reserves in the United States, minable at $8 per pound of contained U308, are in roll-type deposits in the State of Wyoming. The host rocks are arkosic sandstones, deposited in intermontane basins under fluvial conditions, and derived from the granitic cores of mountain...
