Seismicity map of the State of Minnesota
C. W. Stover, B.G. Reagor, S. T. Algermissen
1981, Miscellaneous Field Studies Map 1323
The earthquake data shown on this map and listed in table 1 are a list of earthquakes that were originally used in preparing the Seismic Risk Studies in the United States in the United States (Algermissen, 1969) which have been recompiled and updated through 1979.  These data have been reexamined...

Low-flow characteristics of streams in the Deschutes River basin, Washington
J. E. Cummans
1981, Open-File Report 81-639
The purpose of the study was to determine the magnitude and frequency of low flows of streams in the Deschutes River basin.The streams in the basin usually have their low flows in August and September. Seven-day low flows were smallest in 1952 when annual rainfall at the Olympia airport was...
The Accotink Schist, Lake Barcroft Metasandstone, and Popes Head Formation— Keys to an understanding of the tectonic evolution of the northern Virginia Piedmont
Avery Ala Drake, Peter T. Lyttle
1981, Professional Paper 1205
The newly named Accotink Schist and Lake Barcroft Metasandstone of the Eastern Fairfax sequence are the structurally lowest metamorphic rocks in the northernmost Piedmont of Virginia.

Modeled impacts of surface coal mining on dissolved solids in the Tongue River, southeastern Montana
Paul F. Woods
1981, Water-Resources Investigations Report 81-64
A computer model has been developed for spatial and temporal simulation of streamflow and dissolved solids in the Tongue River from the Tongue River Dam to Miles City, Montana. User-defined plans of surface coal mining and agricultural development permit evaluation of potential changes in dissolved solids resulting from leaching of...
