7. JUNIATA TOWNSHIP. F 2 . 239 



Except at the eastern end it forms the northern escarpment 

 of Middle ridge, the top> and slope of which are covered 

 with its wreckage. It may be seen on the Ridge road near 

 the western end of the township, but is most conspicuous 

 on the northern side of the syncline w T est of Walnut Grove 

 school-honse, where the land is strewn and the road is 

 fenced with its loose blocks. In texture and appearance 

 it very closely resembles the same bed at its southern out- 

 crop, but fossils are exceedingly scarce. Sufficient, how- 

 ever, have been found to establish its place on palaBontolo- 

 gical grounds. The position it occupies in Juniata township 

 is analogous to that in Carroll ; time, however, did not al- 

 low exact measurement. 



Buffalo creek has cut its way through the northern wall 

 of the syncline at Walnut Grove school -house, and the rest 

 of its course lies in the trough formed by the Kingsmill 

 sandstone, which otherwise continues unbroken to the 

 Juniata river at Newport and Rope Ferry. 



In the upper part of the group occur the hard solid beds 

 of green and red sandstone, which in the southern part of 

 the county form the range of hills skirting the Cove mount- 

 ain and which are well shown in the cutting on the North 

 Central railroad opposite Duncannon. Here, however, in 

 the north of the county they are much less hard and form 

 no conspicuous ridge on either the east or west side of the 

 Juniata. Their presence is only indicated by a steep low 

 hill skirting the plain of the Buffalo and gradually diverg- 

 ing as the syncline opens toward the river.
