Limestone, arenite, and shale; Cambrian marine continental-shelf deposits; northern Idaho (IDCmn;0)

State	Idaho
Name	Limestone, arenite, and shale; Cambrian marine continental-shelf deposits; northern Idaho
Geologic age	Middle Cambrian
Original map label	Cmn; Cun
Comments	area of Cmn on state map was mapped as Cambrian unidivided by Miller and others (1999, ref. ID020), comprised of Gold Creek Quartzite, Rennie Shale, and Lakeview Limestone, all of which are Middle Cambrian. Polygons for the upper Cambrian Cun unit on the state map are therefore changed to Cmn, and the unit Cun is deleted.
