center of the trough, between Bissell and Scenery Hill, data for 
determining the depth of the Pittsburg coal are few and it is possible 
that the basin may be somewhat deeper than it is shown. 
AMITY ANTICLINE. 
From the Waynesburg syncline the rocks rise gently to the north- 
west to the crest of the Amity anticline. This was called the Pin- 
hook anticline by Stevenson and White in their reports, the term 
being taken from a name formerly applied to the village of Lone 
Pine. a The name Pinhook has long since gone out of usage, and 
since the village of Amity is located almost directly on the axis this 
name was adopted by Stone in the Waynesburg folio and is here 
used for the northern extension of the same anticline. 
The axis of this anticline crosses the Greene County line near the 
boundary between Morris and Washington townships. From this 
point it takes a slight bend or offset to the east, then continues about 
N. 35° E., passing just east of Amity and through Lone Pine, and 
crossing the National pike 4 miles southeast of South Strabane post- 
office. Beyond this place there is another slight eastward deflection, 
but within 2 miles the axis veers to the north again and takes a course 
about N. 30° E., passing west of Vanceville, through Kammerer, 
and across Nottingham Township to Peters Creek at Anderson. At 
this place its location was very definitely determined, as it passes* 
through the Blanche mine of the Pittsburg Coal Company. 
On the* Greene County line the Pittsburg coal is at an elevation of 
a little over 450 feet, this point being on a sag almost connecting the 
Waynesburg and Nineveh synclines. South of Tenmile Creek the 
axis commences to rise at an average rate of less than 50 feet per 
mile, until H miles south of the National pike it forms an imperfect 
dome with the Pittsburg coal, as determined by well records, at an 
elevation of something over 700 feet. Beyond this point the rise 
does not average more than 20 or 30 feet per mile, except north of 
Kammerer. A mile south of Peters Creek the axis rises abruptly, 
bringing the coal from an elevation of less than 900 feet up to 1,040 
feet just outside the quadrangle. At its north end this anticline is 
identical with the Peters Creek anticline described by Stevenson. 
On the eastern border of the quadrangle, in Nottingham Town- 
ship, east of the Amity anticline, a local trough extends into the area 
for a distance of over 2 miles. It trends west-south westward, 
directly toward another small indentation in the anticline. This 
feature is evidently the cause of the rather sudden deflection of the 
Amity axis at Mingo Creek, and there seems to be a slight depression 
of the axis here. There is no true cross syncline, however. 
At a number of localities on this anticline the lay of the coal is
