In the Ajnity quadrangle only one coal in this formation, the Ten- 
mile, has been opened at one or two points. Several limestones are 
distributed through the formation, but the Prosperity limestone, 
from 100 to ISO feet above the Upper Washington, is the only one 
which seems to be at all important. 
Distribution. -In tins quadrangle the rocks of the Greene formal ion 
reach a maximum thickness of about 400 feet, in Morris Township, 
Greene County, and are best, developed in the southern and western 
pails of the quadrangle. On the highlands along the boundary of 
Greene County, south of Tenmile Creek the formation is continuous, 
having a thickness of 200 to t00feet,as fareastas Bissell. North of 
Tenmile Creek and west of Bane Creek it is well developed through 
Morris, South and North Franklin townships nearly to Washington. 
II forms the greater part of northwestern Amwell and southern South 
Stfabane townships, and in places attains a thickness of oxer 300 feet. 
It is well developed as far north as (he Baltimore and Ohio Railroad, 
but beyond appears only in small isolated areas. Throughout West 
Bethlehem Township il caps many of the higher hills with a local
