'AS'2 1' REPORT OF PROGRESS. E. W. CLAYPOLE. 



Susquehanna ; Limestone ridge to Ickesburg and Millers- 

 tow n and mound Pfoutz's valley, and Dick's hill, by Little 

 mountain, to the Susquehanna at Marysville. The return 

 oi* Mahanoy ridge is prevented by the Perry county fault, 

 which cuts it off near the Perry Furnace. 



Prom the point of convergence these ranges continue as 

 a single simple anticline to the Susquehanna river ; gradu- 

 ally subsiding, it there sinks beneath the water forming a 

 reef of rocks and a rapid. Some additional details will be 

 found in the report on Buffalo township. 



A quarry was opened some years ago on the south side 

 of the mountain about a mile from the Susquehanna, or Big 

 river as it is commonly called in the district, but it has not 

 been worked recently. 



The Hamilton fossil ore. 



An outcrop of this ore exists along the southern side of 

 the Hamilton sandstone, but so far as I am aware no at- 

 tempt has been made to open or work it except at the two 

 ends of the range in the township. On the Susquehanna 

 at Girty s Notch several drifts were run in some years ago 

 and a considerable quantity of ore taken out. The prop- 

 erty is now in the possession of the Messrs. McCormick and 

 the ore is not worked. Its quality, so far as can be judged 

 from appearances, is the same as in most other exposures 

 along this line of outcrop. I was informed that the mine 

 had been abandoned on account of the poverty of the ore 

 but am not aware that the ore has been analysed. It is 

 said to be very sandy. 



Another exposure from which a few tons have been taken 

 is :it the other end of the mountain on the Juniata river. 

 Here a quantity of the ore is lying with the usual appear- 

 ance and of the usual quality bnt this opening also has been 

 abandoned. It lies on the south slope of the ridge brought 

 up by the fault. A few hundred yards farther south on 

 the upper surface of the sandstone of tin 4 arch above men- 

 tioned a small hole has been dug exposing the Hamilton 

 fossil <»re. but only imperfectly.
