CONCLUSIONS. 



There is an unconformity of varying, but considerable, re- 

 lief between the Permian and Cretaceous systems. 



The eastern part of the Dakota sediments was deposited in 

 shallow water along the shore and in estuaries and lagoons, as 

 shown by the nature of the formation and the fossil content. 

 Some of them may be of sub-serial origin. 



The shore-line of the Cretaceous sea was probably some dis- 

 tance to the east of the main body of the Dakota outcrop, as 

 is shown by the presence of outcrops east of Hanover, Wash- 

 ington county, and in the vicinity of Junction City.
