GEOLOGY OF THE REMSEN QUADRANGLE 43 



veloped. The greatest accumulation of kame-moraine materials 

 (sand and gravel) is in the vicinity of Hinckley and for 5 or 6 miles 

 northward where it forms a ridge rising from 100 to 200 feet above 

 the surrounding country [see pi. 10]. Many kame hills and kettle 

 holes (not shown on the map) occur in this locality. 



Sand hill at the extreme southeast is another example of the 

 kame-moraine hills. The deposit here consists of sand and gravel, 

 is crudely stratified, and is several hundred feet deep. 



Minor kames occur i mile east of Bardwell Mill and 2 J miles 

 northwest of Enos, and 2 and 3 miles northeast of Remsen. 



A little over a mile south of Forestport there is a group of kame 

 hills in the midst of which lies a " kettle hole," 30 or 40 feet in depth. 

 Three such hills forming a group, 3 miles northeast of Forestport 

 have a deep " kettle hole " between them. 



Stratified clay deposits 



Thinly stratified or laminated cla3^s have been noted in a number 

 of locations, and they certainly indicate the former presence of 

 lakes. Such clay beds, lying between the 1200 and 1300 foot 

 levels, occur over the whole area between West Canada and Black 

 creeks and to an unknown distance eastward beyond the map 

 limits. These clays also extend a little north of West Canada creek 

 and for a considerable distance south of Black creek. The best 

 exposures may be found along the creek south of Northwood and 

 along Black creek between Grant and Gray. Sand everyw^here 

 rests upon the clay-above the 1300 foot level. The evidence is con- 

 clusive that an extensive body of water once occupied the area here 

 described. The water, in all likelihood was held in by the ice front 

 or morainic deposits or both on the south side and by the high 

 Precambric land on the north side. 



Similar clay beds outcrop extensively along Black river between 

 I and 2 miles southwest of Enos and again at the small lakes 2 

 miles east of Bardwell Mill. Between these points clay beds also 

 appear. The exposures all lie between the 1200 and 1260 foot 

 levels and argue for the existence of a lake of considerable size. 

 This water body and the one above described were at approximately 

 the same level and they may have been joined during part or all of 

 their „ . 



Strat...^ ' clays ma}^ be seen along West Canada creek south of 

 Trenton Fano at a much lower level (740 feet). This water body 

 was formed at a later time when the ice had retreated farther south. 



Another lake in the extreme northwest extending to an unknown
