This map is one of a series of three reconnaissance geologic maps of the southern Misheguk Mountain quadrangle (fig. 1). Because the geology in all three map areas is similar, a composite map explanation has been designed to facilitate their combined use and provide the reader with a better perspective of the regional geology. There are some rock units and allochthons which do not occur on all three maps. For this reason, the explanation contains more rock units than occur on any one map. Rock units which appear on the accompanying map are indicated by an asterisk beside the map symbol in the explanation.
