Regional mapping of surficial glacial features at 1:500,000 scale 

 shows the wetland site just within a lobe of a mapped glacial 

 advance (apparently correlative with the advance repsponsible for 

 the Sweet Grass Hills end moraine) . The glacial deposits in the 

 area are mapped mainly as "ground moraine" , although there is a 

 thin band of end moraine shown associated with the ice advance 

 limit. Concentrations of drumlinoid features and crevasse-fill 

 deposits are shown within this advance lobe. Beyond the mapped 

 maximum position of this lobe, the surface is mapped as (presumably 

 older) "ground moraine".

The wetland is shown to be underlain by a broad area of 

 undifferentiated Colorado Shale. Generalized regional mapping 

 provides no information regarding surficial deposits.
