Clinch fault little more than half a mile away. This dip becomes gentler 

 further up Bull creek, so much gentler that the following measurements 

 obtained in crossing from Bull creek to Russell creek are probably not far 

 out of the way : 



Middle Coal Measures. 



1. Sandstone 25' 



2. Shales 10' to 15' 



3. Coal bed blossom 



4. Sandstone and shale 120' 



5. Coal bed blossom 



6. Sandstone and shale 100' 



7. Coal bed blossom 



8. Sandstone and shale to Bull creek 180' 



The intervals between these coals are very suggestive of their relation to 

 beds on Powell river, but one is not justified in making identifications on 

 so slender a basis. 



Russell creek is reached by the road at little more than a mile from 

 Clinch river. The dip at Mr. Dickenson's house is distinctly south of 

 south-east. Mr. Dickenson digged coal on a little branch of Russell creek 

 at about one third of a mile north from the road. The exposure is very 

 indifferent, though it extends for more than fifty feet. Manifestly, the dip 

 is considerable, and the coal is very much twisted. Prof. Lesley, in his 

 notes on this region, regards this coal as the same with that mined north 

 from Guest's station. 



Coal beds were seen between Russell and Whetstone creeks at 25, 85, 157 

 and 205 feet above the former stream, and a compact sandstone with nests 

 of very coarse conglomerate makes the summit. The dip varies from 

 43 to 45 degrees on the Russell side of the ridge, but beyond the 

 summit it diminishes rapidly, and is reversed at an inconsiderable dis- 

 tance. Prof. Lesley gives a diagram of this hill in his memoir. Exposures 

 cease soon after the summit has been passed, and no more occur until 

 beyond the river, the abrupt wall of Knox beds shows that the Clinch 

 River fault has been crossed. The road reaches Clinch river at Kincaid's 

 hole, whence it follows the stream to Wheeler's ford at the mouth of Lick 

 creek. The river crosses the fault about midway between the two points. 

 The ridge marking the course of the fault is cut av7ay for some distance on 

 both sides, but it quickly regains its height, and is very bold where cut by 

 Lick creek at a little way from the river. The immediate line of faulting 

 was not seen, but the rocks are turned up sharply on both sides, the Knox 

 beds dipping south eastwardly at forty degrees, and a sandstone above the 

 fault dipping even more sharply in the opposite direction. The limestones, 

 however, are more contorted than the Coal Measures beds, for they are 

 thrown into a succession of folds, one of which passes very near to Mr. 

 Field's house, a mile north-east from Lick creek, where the dip is N. 40° 

 E. at 20 degrees.
