Kleinschmidt Lake underlain by "Younger Pinedale" till of the North 

 Fork provenance. The contact with the outwash gravels forming 

 Kleinschmidt Flat is about 1 mile northeast of Kleinschmidt Lake. 

 No information regarding stratigraphic relations is provided, but 

 from surface relationships it appears possible that advance outwash 

 deposits might underlie till in the vicinity of Kleinschmidt Lake.

Regional compilation of bedrock geologic mapping at 1:250,000 scale 

 shows the North Fork Blackfoot source area for the North Fork till 

 to be underlain by Proterozoic (Belt) formations from the Spokane 

 Formation through the Bonner Formation, including large areas of 

 Helena Formation (dorainantly carbonate lithologies) in the lower 

 and middle basin. The upper basin includes areas of 

 undifferentiated Cambrian and Devonian rocks.

Regional mapping at scale of approximately 1:125,000 shows the 

 entire contributing drainage underlain by the calcareous and 

 dolomitic Wallace Formation of Proterozoic Y (Belt) age. The 

 Quartz Creek Fault, a normal fault downdropped to the west, is 

 shown immediately underlying the Lafoe Lake wetland, raising the
