NOTE
    Geologic data for the Wyoming State map were derived principally from compila-
tions of 1 degree x 2 degree quadrangles, which in turn incorporated data from many 
other geologic maps.  All quadrangle maps were generalized as necessary to fit require-
ments of scale; some sources were modified by individuals listed at the end of the refer-
ence or by the authors of the Wyoming map.  The numbers following most references 
are keyed to the 1 degree x 2 degree quadrangles shown in figure 3; although the maps 
in the references may cover a larger area, only the quadrangles for which data were used 
in the preparation of this map are cited.
