GEOLOGY AND PALEONTOLOGY OP THE SCHOHARIE VALLEY 255 



New Scotland slope to the Becraft Orlskany terrace, which is 

 reached by a final ascent over Becraft ledges. On this terrace 

 it continues to the home of Mr George Acker, near which the 

 following section is made. A section of this hill was published 

 by Prosser.^ The present section is largely based on that but 

 some corrections of measurement are made. 



Feet Inches 



o Onondaga limestone, forming the upper lime- 

 stone cliffs and the top of the hill which is 

 wooded. From 11 to 15 feet are shown in the 

 cliffs. The total thickness present is, accord- 

 ing to Prosser 56 



n Schoharie grit, not exposed on this side of the 



hill, estimated 6-8 



m Esopus shale, not exposed, except at the top 

 where large slabs with Spirophyton 

 caudagalli occur but forming with the 

 Schoharie a continuous steep slope from the 

 Oriskany terrace to the cliff of Onondaga^, . . 95 



1 Oriskany sandstones, well exposed in the yard 

 of George Acker. The red barn visible from 

 Schoharie stands on the top of this bed, where 

 the upper hard surface, marked by Spirophy- 

 tonlike tracings, have been laid bare by ero- 

 sion of the Esopus. Fossils numerous and 

 easily obtained from the loose blocks lying 

 everywhere 6 3 



k Port Ewen limestones, a dark rather fine crin- 

 oidal lime sandrock resembling the Coey- 

 mans. Approximately 9 3 



j Becraft limestone, forming a cliff below the 

 road in front of Mr Acker's house, 15J feet

2 Prosser writes me that his section included the 6 feet of Schoharie grit. 

 For that interval the barometer gave 108 feet ; but it v^^as leveled with a 

 hand level by an engineering student who reported 121 feet and that thick- 

 ness was used in his section.
