ALABAMA 127 



Waldens ridge as it crosses northwest Georgia becomes Raccoon 

 mountain, and the name is retained in Alabama. Sequatchie becomes 

 Browns valley and continues practically to the south line of Blount 

 count} 7 , about 50 miles from the Tennessee line. On the east, Raccoon 

 mountain is cut off by Wills valley, continuous with the Great valley of 

 Tennessee and separating Raccoon from Lookout mountain, which 

 begins just north from the Tennessee line. 



In Dade county, the most northwesterly in Georgia, Mr McCalley's 

 section at the Dade mines is 



Feet. Inches. Feet. Inches 



1. Cliff sandstone [Etna] 75 



2. Cliff coal [Etna] 2 to 6 



3. Shale 50 



4. Dade coal 17 to 1 



5. Shale and clay 45 



6. Bed Ash coal bed 3 to 6 



7. Fireclay and sandstone 81 



8. Coal bed 1 2 to 10 



9. Shale to the Limestone 40 



about 225 feet between the Etna sandstone and the Lower Carboniferous 

 limestone. Farther west, near the Alabama line, at the Castle Rock mines, 

 the place of the " Red ash " coal bed is concealed, but the other beds are 

 exposed. The interval from the lowest coal to the limestone appears to 

 be 250 feet, and the thickness of the Lower measures is about 500 feet. 



The Etna sandstone forms the main bluff on the west side of Raccoon 

 mountain in Jackson county of Alabama. It is 60 feet thick at 4 miles 

 from the Georgia line, but increases to 100 feet on Long Island creek, 4 

 miles farther southward. The immediately underlying Etna coal bed 

 persists in the sections and rarely exceeds 2 feet. A coal bed at about 

 50 feet above the Etna sandstone is shown in many sections, varying 

 from 6 inches to 3 feet. It is evidently the same with the Sewanee of 

 Colton's section and seems to be very near the place of the Cashie coal 

 bed in Gibson's Blount Mountain section. That name will be used in 

 the descriptions. Mr McCalley's section at 18 miles from the Georgia 

 line is 



Feet. Inches. Feet. Inches
