DISCUSSION OF STRATIGRAPHY. 
When the attempt to unravel the stratigraphy of the group was begun, 
some trouble was encountered: (1) the unconformity which limits the 
group at the top; (2) the deposit of glacial drift in the area bordering 
Richland Creek; (3) the solution of the underlying Mitchell limestone on 
the eastern border, developing large folds and the collapse of strata; (4) 
selution of the limestone layers in the Solsberry formation; and (5) the 
fact that the Solsberry sandstones and shales have a tendency to be 
more or less cross-bedded and lenticular, as would be expected of a shore 
deposit. These factors detract somewhat from the correct interpretation 
of the stratigraphy. 
Sections in the underlying Mitchell limestone in the region studied 
show that in most cases the top of the latter formation consists of a very 
typical white odlite, differing materially from that of the Chester. Ash-
