DEVELOPMENT OF THREE SUCCESSIVE PENEPLAINS IN KANSAS 

 BY J. W. BEEDE 



(Abstract) 



1. A pre-Dakotau peneplain extends westward from the east-facing Flint 

 HilLs escarpments and passes beneath the Comanche-Dakota rocks, north of the 

 latitude of Great Bend, and grades into the Great Bend lowland south of that 

 latitude, north of the Arkansas River. It also begins with the Gypsum Hills 

 escarpment and extends westward to the Comanche and Tertiary deposits 

 southwest of the Great Bend lowland in Kansas and Oklahoma. Both of these 

 regions are low plateaus and they are designated the Dwight and .^tna pla- 

 teaus respectively. 



2. The Cretaceous sediments of Kansas were peneplained prior to the deposi- 

 tion of the Pliocene sediments of western Kansas, and this peneplain is now 

 represented by the high divides of the central third of the State, and the 

 divides and valleys of the western edge of the State, north of the Arkansas 

 River. Much of this area is covered with Tertiary sediments. This peneplain 

 is designated the Paradise peneplain. 



3. Later a broad peneplain was developed within the Paradise plain, appar- 

 ently before the deposition of the early Pleistocene sediments of the Great 

 Plains. It varies from three or four miles to twenty miles in width with the 

 nature of the rocks of the region. This feature is designated the Wilson 

 peneplain and is regarded as latest Pliocene age. 



4. East of the Dwight Plateau two similar peneplains were developed that 

 seem to be continuous with the Paradise and Wilson peneplains along the 

 valley of the Smoky Hill River, and the two sets are regarded as identical.

HYPOTHESIS FOR THE RELATION OF NORMAL AND THRUST-FAULTS IN 

 EASTERN NEW YORK 



BY GEORGE HALCOTT CHAD WICK 



(Abstract) 



A theory is presented of the secondary or corollary relation of the Adiron- 

 dack-Mohawk step-faults to the great charriage movements of New England 

 over eastern New York, which, by overloading, may have depressed successive 

 fragments of the overridden area. The sedimentary contact of the Cobleskill 

 limestone on the translated mass of Normanskill shale at Catskill is cited as 

 proof of the early date at which this thrusting was initiated, and the similar
