THE ADIRONDACK GRAPHITE DEPOSITS 1/ 



the anticline are pitching southward, as can be seen from figure 2. 

 The mine openings to the west are on the western side of the syncline 

 and thus the dip is greater than is the case in the eastern group of 

 pits ; hence the reason to question the presence of the fault suggested 

 by Professor Crosby. 



Future of the property. Although specimens can be gathered 

 that show a good display of graphite, the deposit, like most of 

 them in the northern area, is of the limestone and contact type which 

 experience has shown to be rarely of sufficient regularity to have 

 commercial importance. 



The writer is indebted to Mr D. G. McGrew and Mr Charles 

 Rowland for information about the Buck mountain locality. 



The Penfield Pond Prospect 



Located near the southern boundary of the township of Crown 

 Point, one-half of a mile west of Penfield pond, very close to the 

 8o° angle in the boundaries between Crown Point and Ticonderoga. 



It is a small limestone deposit of rather striking characteristics 

 but of no commercial importance. Specimens of white, grading to 

 pink and red, limestone carrying large flakes of graphite (one-fourth 

 of an inch in diameter) may be obtained. The Crown Point 

 Graphite Company first opened a deposit near Penfield pond, but 

 whether or not this is the locality is not known. 



The Crown Point Graphite Company 

 Location. This recently abandoned property is situated in the 

 township of Ticonderoga 2 Y / 2 miles southwest of Ironville, one- 

 fourth of a mile south of the road which runs west past Eagle 

 lake (Lake Chilson on the map), and 7^2 miles southwest of Crown 

 Point Center and 10 miles from Ticonderoga. It lies within the 

 Paradox Lake quadrangle. The mine, located on the northern slope 

 of a low r ridge overlooking a swamp, w r as opened about 1907 and 

 has lain idle since 1910. 



Workings. The workings consist of four inclined shafts 

 nearly in line (three abandoned and one recently worked). The 

 dip of the rocks and hence of the shafts is 55°-6o° southward. 

 The main shaft is reported to be 72 feet deep " from which the 

 miners have drifted eastward along the ore bed, removing a con- 

 siderable amount of ore by stopping and finally reaching the surface 

 again about 150 feet east-northeast of the shaft." 1
