J(,'iniiii<i^s Rmi it covers about 2000 feet and the result of several measure- 

 ments indicates that the formation is between 1900 and 2000 feet in 

 thickness. In the eastern part of Garrett County Dr. Martin stated that 

 " The thickness of the formation varies from 1800 to 2200 feet " but 

 decreases toward the west and in the western area " is about 1200 or 1400 

 feet." ' The Catskill forniation represents at least part of the Catskill 

 formation of Xew York and Xo. IX of Pennsylvania. 



DISTRIBUTION OF THE CATSKILL FORMATION 



From Pigskin to Timber Kidgc a belt of the Catskill formation, varying 

 from li/> to l-)4 miles in width, crosses the state from the northeast to 

 the southwest. 



A belt of the Catskill formation crosses the state, east of Sideling Hill, 

 varying from a mile to I14 miles in breadth, extending well up the slope. 

 I'he u])per part of Sideling Hill is composed of the Pocono formation 

 while on the western slope is another parallel belt of the Catskill formation, 

 about a mile in breadth, crossing the state and, for part of its distance, 

 extending as far west as Sideling Hill Creek. These two belts may be 

 called the Sideling Hill Catskill areas. 



Finally, the extreme northwestern corner of Washington County is 

 covered by the Catskill formation, which belongs in the belt of this 

 formation situated just west and ])arallel to the Sideling Hill Creek area 

 of the Jennings formation. 



In Allegany County the Catskill forms a broad belt on each side of 

 Town Hill and outcrops in a linear area on the east slope of the Alleghany 

 Front. 



In Garrett County it flaid\s the Jennings on both sides of the Oakland 

 anticline and outcroi)s in a large elliptical area in the center of the 

 Accident anticline, near Accident.
