MOUNT PLEASANT TOWNSHIP, WASHINGTON COUNTY. 
Mount Pleasant Township lies southeast of Smith and Cross Creek 
and northwest of Chartiers townships. It occupies most of the 
southeastern quarter of the quadrangle. 
II ashington formation .—Through the central and southwestern 
parts of the township the larger portion of the surface is composed 
of the Washington formation. The Waynesburg “ B ” coal is espe¬ 
cially prominent near Hickory and along the ridge road to the east, 
also in the vicinity of Miller Run, The Washington coal outcrops 
at Prospect Church, west of Hickory, and thence southward through 
all the higher hills on the western side of the township, along the 
ridge leading to Cross Creek village, at Rankin schoolhouse, and 
farther east, through the higher hills. The coal makes on all roads 
a heavy blossom that is easily distinguished by its size and mealy 
appearance. The high ridge between the waters of Chartiers Creek 
and Cross Creek reaches through the Washington formation, the 
Upper Washington limestone showing near the summit.
