geology. Sample site is shown to be near the contact of modern 

 alluvium and "valley facies" of late Pleistocene till. The till 

 facies is described as loose and having a sandy matrix. The knob 

 elevated above the valley floor is shown as a kame deposit on this 

 map, rather than a drumlin as it is described elsewhere. There is 

 no subsurface or hydrologic information included.

Regional mapping at 1:125,000 scale shows the Tew WPA apparently 

 underlain by the Lebo Shale member of the Fort Union Formation, 

 with mappable accumulations of "alluvium" (probably lacustrine or 

 paludal sediments) shown within two or three nearly-closed basins. 

 The text provides no description of these surficial sediments nor 

 any discussion of the hydrologic characteristics of the map area.
