[Well completed in 1905. Authority, F. II. Oliphant. No samples. Geologic correlations by Charles 
Butts.] 
This skeleton log of a well in Armstrong County is given because of its depth. The drill 
passed through rocks of Carboniferous and Devonian age, which are included in the Alle- 
gheny and Pottsville (Pennsylvanian) and Mauch Chunk and Pocono (Mississippian) of the 
Carboniferous system and the Catskill and Chemung of the Devonian. 
The geology of a large part of Armstrong County and the occurrence of the various oil 
and gas sands are described in the Kit tanning folio (No. 115) and the Rural Valley folio 
(No. 125) of the Geologic Altas of the United States.
