with subordinate dolomitic siltite and argillite. Stromatolitic 

 and oolitic beds and molar tooth structures described in upper 

 portions of the unit. Dips are to the east at 25 to 40 degrees. 



The upper portion of the range-front fan complex is mapped as a 

 band of colluvium below the Proterozoic outcrops. No other 

 information regarding surficial deposits of the sample site is 

 provided.

Title: Geologic map of Montana 



Series: U.S. Geological Survey, no series 



Date: 1955 



Statewide compilation at 1:500,000 scale shows the Creedman Coulee 

 basin in Montana underlain mainly by the Bearpaw Shale of Late 

 Cretaceous age, with some Late Cretaceous Judith River Formation 

 underlying the western tributaries. The geology of the Canadian 

 portion of the basin is not shown. 



This map shows generalized prequaternary geology only, and provides 

 no information regarding surficial deposits. Presumably the 

 Creedman Coulee basin surficial materials are glacial deposits of 

 unknown thickness and character. 



Neither the Geoindex lat-long search nor manual searching of the 

 Montana Bureau of Mines and Geology produced any more useful 

 geologic map coverage for this area.
