Seismicity map of the state of South Dakota
B.G. Reagor, C. W. Stover, S. T. Algermissen
1981, Miscellaneous Field Studies Map 1325
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 1977.  These data have been reexamined...
Map showing paleontological control of Paleozoic stratigraphy in New England
Marland P. Billings, Peter T. Lyttle
1981, Miscellaneous Field Studies Map 1302
Assignment of Phanerozoic stratigraphic units to their proper place in the geologica time scale is based primarily on paleontology.  Radiometric methods are becoming increasingly important (Naylor, 1976), particularly where paleontological data are lacking.  This map and text are concerned only with the paleontological data bearing on the Paleozoic stratigraphy of...

Map showing vegetation distribution in the central part of the East Tintic Mountains, Utah
Nancy Milton, Daryl P. Madura
1981, Miscellaneous Field Studies Map 1195
With the development of remote sensing technology has come the capability of defining and mapping plant communities by means of their spectral properties.  Such maps will be an important aid in resource evaluation and management, especially in densely vegetated and remote areas of the world. This study in part of a...
