Uniontown coni .—The Uniontown coal is found in the New Alex¬ 
andria ridge and in the western part of the township. All of the 
comparisons of elevations for the determination of intervals have been 
credited to Cross Creek Township (p. 91). 
Meigs Creek coal .—The Meigs Creek coal is a good geologic marker 
over most of the township, although its thickness is in most places 
less than 2 feet. The following comparisons of elevation were made 
for determining the thickness of the interval between the Meigs 
Creek coal and the Pittsburg coal:

Pittsburg coal .—The Pittsburg coal is present throughout the town¬ 
ship and its outcrop is well up the sides of the hills. It is usually 
accompanied by limestones above and below. The Rider coal is uni¬ 
formly present, with a thickness of about 1 foot. 
Ames limestone .—The Ames limestone is well developed in the 
eastern part of the township. Heavy outcrops were examined on 
Tarrs Run and back of the mine in Brilliant. In all the runs south 
of this point it was found, but it is generally thin and in some places 
hard to locate. The following comparisons of elevation were made 
for determining the interval between the Ames limestone and Pitts-

CLAY TOWNSHIP, HANCOCK COUNTY, W. VA. 
In describing the areal geology and the intervals in the townships 
of West Virginia, a small portion of Pennsylvania along the eastern 
limit of the quadrangle will be included. 
The formations in Clay Township are much higher in elevation 
than in any other portion of the quadrangle. The section exposed 
extends from the middle of the Conemaugh formation through most 
of the Allegheny formation.
