124 OTL AND GAS; OHIO, WEST VIRGINIA, PENNSYLVANIA. 
The Big Injun sand has a thickness of about 200 feet, with the top 
averaging about 1,000 feet below the Pittsburg coal. The Squaw 
sand occurs at 1,300 to 1,330 feet below the Pittsburg coal. The 
Berea sand, or Thirty-foot shells, as it is called in the records, is 
from 1,G00 to 1,650 feet below the coal and by four measurements 
occurs from 180 to 205 feet above the Hundred-foot sand. The top 
of the “red rock v is a little less than 100 feet above the Hundred-foot 
sand, which is the producing gas sand of the township. This sand 
is from 9 to 11 feet thick, and occurs 1,780 feet below the Pittsburg 
coal in the northern part of the township and 1,846 feet below in the 
southern part. 
Few wells have been drilled below the Hundred-foot sand. In the 
G. Cunningham well (No. 822) the Thirty-foot sand was found 99 
feet below the Hundred-foot, the Gordon Stray IT 1 feet, the Gordon 
193 feet, the Fourth 255 feet, and the Fifth as shells 348 feet below 
the Hundred-foot sand. 
CROSS CREEK AND INDEPENDENCE TOWNSHIPS, WASHINGTON 
COUNTY. 
Cross Creek Township, which includes most of the drainage of 
Cross Creek, lies to the east of Jefferson, south of Smith, and west 
of Mount Pleasant townships. Only a part of Independence Town¬ 
ship is included in the Burgettstown quadrangle. This lies in the 
southwest corner, to the south of Jefferson and Cross Creek town¬ 
ships. 4 he surface of Cross Creek and Independence townships is 
composed mostly of the Monongahela and Washington formations. 
Marking strata above Washington coal .—The Lower Washington 
limestone is well developed above the Washington coal. It is the 
highest bed found in most parts of the township. At and to the 
north and east of Cross Creek village, however, the dip of the forma¬ 
tion into the Cross Creek svncline brings the Jolly town coal and the 
Upper Washington limestone down to the level of the highest hills. 
Washington coal. —The Washington coal is the principal geologic 
marker throughout the greater portion of Cross Creek Township. 
Apparently the coal is of considerable thickness, showing as a prom¬ 
inent blossom on the roads. In the vicinity of Cross Creek village 
it is halfway down to valley level east of the village and a hundred 
feet below town on the west. It is near the summit of the ridge 
between Middle Fork and North Fork of Cross Creek. Between 
Middle Fork and the north branch of South Fork it is nearly at the 
heads of the valleys. On the ridge between the two branches of 
South Fork the Washington coal is near the summit, but south of the 
South Fork it is about 100 feet below the summit of the rid<m. 
In Independence Township the Washington coal is present in all of 
the high knobs along the southern boundary of the quadrangle.
