SOUTH MOUNTAIN SECTION. 
By E. M. Kindle. 
A small ravine descending from the summit of South Mountain, 
opposite Leroy, exposes a section directly across To wanda Creek Valley, 
opposite the Gulf Brook section. The alluvium of the valley conceals 
about 450 feet of beds lying between the top of the Gulf Brook and the 
base of the South Mountain sections. About 300 feet of these concealed 
beds are exposed in the Towanda Narrows section. The South Moun- 
tain section continues the exposures of the previously described sec- 
tions up to the Barclay coal bed. South Mountain is a synclinal 
mountain, and the strata on the north face, where this section was taken, 
have a very small dip to the south, the maximum being 10° at the base 
of the section. 
The section is as follows: 
Section 1455 C, at South Mountain, Bradford County, Pa.
