Marine terraces of the western Aleutian Islands, Alaska
Robert H. Morris
1971, Report
The islands of the Rat Islands group, which includes Amchitka Island, have active sea cliffs, well-developed intertidal platforms, and a prominent submarine platform at -100 m. These features have not been disturbed by tectonic activity for the past 17,000 years. The islands of the Delarof Islands group, located east of...
Calculated in situ rock density from gravity observations, UA-1 (Cannikin) emplacement hole, Amchitka Island, Alaska
D.L. Healey
1971, Report
Gravity observations were made on the ground surface and at a depth of 5,854 feet in drill hole UA-1. Two attempts to measure the free-air gradient utilizing the headframe over the drill hole were unsuccessful owing to mechanical vibrations in the structure. Because of the uncertainty in the measured free-air...

Bottom sediments on the continental shelf off the northeastern United States -- Cape Cod to Cape Ann, Massachusetts
John Schlee, David W. Folger, Charles J. O’Hara
1971, Open-File Report 1639
These reconnaissance maps have been constructed to show the areal distribution of major types of bottom sediment and some of their constituents on the sea floor off Massachusetts between Cape Ann and Cape Cod (41°45'N and 42°50'N and west of 70°-00W). They are intended to serve as a guide to...
Ground-water resources: Cumberland County, New Jersey
James G. Rooney
1971, Special Report 34
Cumberland County is located in the Atlantic Coastal Plain physiographic province along the northeastern shore of Delaware Bay in Southwestern New Jersey. An average annual hydrologic budget was computed for Cumberland County. Water gains are: precipitation, 1,050 mgd (million gallons per day); surface-water inflow, 142 mgd; ground-water inflow negligible. Water...
Floods in Arkansas, magnitude and frequency characteristics through 1968
James L. Patterson
1971, Arkansas Geological Commission Water Resources Circular 11
Techniques are presented for estimating the magnitude and frequency of floods on Arkansas streams. Modern topographic maps now available and computer techniques facilitate in making a comprehensive analysis in which physical and climactic characteristics of river basins are related to flood characteristics at gaging stations. Equations derived from the analysis...
Ground-water resources of Cass and Marion Counties, Texas
Mathew E. Broom
1971, Report 135
Cass and Marion Counties, an area of 1,325 square miles in northeast Texas, are underlain by the Cypress aquifer which is composed of the Wilcox Group, Carrizo Sand, Reklaw Formation, and Queen City Sand, all of Eocene age. These geologic units are for the most part hydraulically interconnected and generally...
