James H. Dover, William B. N. Berry, Reuben James Ross Jr.
1980, Professional Paper 1090
Recent geologic mapping in the northern Pioneer Mountains combined with the identification of graptolites from 116 new collections indicate that the Ordovician and Silurian Phi Kappa and Trail Creek Formations occur in a series of thrust-bounded slices within a broad zone of imbricate thrust faulting. Though confirming a deformational style...
Estimating the costs of landslide damage in the United States
Robert W. Fleming, Fred A. Taylor
1980, Circular 832
Landslide damages are one of the most costly natural disasters in the United States. A recent estimate of the total annual cost of landslide damage is in excess of $1 billion {Schuster, 1978}. The damages can be significantly reduced, however, through the combined action of technical experts, government, and the...

Experiments using a convertible data collection platform
Stanley R. Addess
1980, Open-File Report 80-123
Experiments under the sponsorship of the U.S. Geological Survey in the use of a convertible data collection platform (CDCP) were performed by 13 organizations. Success in its use was related directly to the resources applied by the experimenter. After design faults were corrected by the manufacturer, most of the problems...
Geophysical-geological analysis of Fairfax County, Virginia
David L. Daniels
1980, Open-File Report 80-1165
Aeromagnetic, aeroradioactivity, and gravity surveys of Fairfax County, Virginia, are interpreted with the aid of existing geologic data and local geophysical measurements. Highly magnetic metasedimentary rocks of the Peters Creek Schist and Sykesville Formation produce most of the magnetic anomalies of Fairfax County. In contrast, the granitoid rocks of the...
Makah Formation — A deep-marginal-basin sequence of late Eocene and Oligocene age in the northwestern Olympic Peninsula, Washington
P. D. Snavely, A. R. Niem, N. S. MacLeod, J. E. Pearl, W. W. Rau
1980, Professional Paper 1162-B
The Makah Formation of the Twin River Group crops out in a northwest-trending linear belt in the northwesternmost part of the Olympic Peninsula, Wash. This marine sequence consists of 2800 meters of predominantly thin-bedded siltstone and sandstone that encloses six distinctive newly named members--four thick-bedded amalgamated turbidite sandstone members, an...
Technique for estimating magnitude and frequency of floods in Maryland
David H. Carpenter
1980, Open-File Report 80-1016
A method is presented for estimating flood magnitudes for natural drainage basins without urban development or regulated flow. The method was developed by multiple-regression techniques and applies to floods with recurrence intervals from 2 to 100 years.The State is divided into three regions, and sets of equations for calculating peak...
Paleozoic and Mesozoic deformations in the central Sierra Nevada, California
Warren J. Nokleberg, Ronald Wayne Kistler
1980, Professional Paper 1145
Analysis of structural and stratigraphic data indicates that several periods of regional deformation, consisting of combined folding, faulting, cataclasis, and regional metamorphism, occurred throughout the central Sierra Nevada during Paleozoic and Mesozoic time. The oldest regional deformation occurred alono northward trends during the Devonian and Mississippian periods in most roof...

A review and evaluation of alternatives for updating U.S. Geological Survey land use and land cover maps
Valerie A. Milazzo
1980, Circular 826
Since 1974, the U.S. Geological Survey has been engaged in a nationwide program of baseline mapping of land use and land cover and associated data at a scale of 1:250,000.

Relationships between basic soils-engineering equations and basic ground-water flow equations
Donald G. Jorgensen
1980, Water Supply Paper 2064
The many varied though related terms developed by ground-water hydrologists and by soils engineers are useful to each discipline, but their differences in terminology hinder the use of related information in interdisciplinary studies. Equations for the Terzaghi theory of consolidation and equations for ground-water flow are identical under specific conditions....
