Map showing slope movements in the Oak Forest Quadrangle, Greene County, southwestern Pennsylvania
J. S. Pomeroy
1986, Miscellaneous Field Studies Map 1794
This map is the first example in the eastern United States of a 1:24,000-scale 7.5– minute quadrangle map that identifies areas with slope—stability problems in detail. Such a map enables the user to make a rapid evaluation of the potential for mass movement. Furthermore, detailed slope movement inventory of this...

Thermal maturity map of the lower part of the Upper Cretaceous Mesaverde Group, Uintah Basin, Utah
Vito F. Nuccio, Ronald C. Johnson
1986, Miscellaneous Field Studies Map 1842
The ability of rock to generate oil and gas is directly related to the type and quantity of kerogen and to its thermal maturity; therefore, thermal maturity is a commonly used tool for oil and gas exploration. The purpose of this study ws to provide a thermal-maturity map for the...

Estimated resources of non-leased federal coal, Powder River Basin, Montana and Wyoming
V. A. Trent
1986, Miscellaneous Field Studies Map 1887
Maps are generated by combining digital ownership data with geologic resource estimates and other spatial coal data in a geographic information system (GIS). For example, we merged the newly compiled Federal coal ownership files with resource calculations from the 1970's for the Powder River Basin (Trent, 1986). For the first...
