GEOLOGY OF CHILHOWEE MOUNTAIN, IN TENNESSEE. 87 
of Chilhowee must have been removed before deposition of 
the Knox took place. It is most likely that the removal was 
due to erosion, as the Chilhowee surrounds the cove and 
there is no evidence of a fault, least of all a circular fault. 
If Chilhowee sandstone was eroded there, it is likely that the 
present anticline was an original one and furnished the locus 
for erosion of the pre-Knox basin. 
(7) Although these areas do not prove post-Chilhowee ero¬ 
sion, they do present a strong probability of it. The salient 
fact in them is the conjunction of Knox dolomite and Chil¬ 
howee sandstone without the Cambrian beds that precede 
Knox in the valley. This contact continues northeast into 
Virginia for at least seventy-five miles, with an overlap of all 
the later Cambrian beds. At Balcony Falls, Virginia, Mid¬ 
dle Cambrian comes between Chilhowee and Knox. Whether 
this overlap could be simply a lapse of time, with neither 
deposition nor erosion, is a difficult question to answer. Such 
conditions appear to occur among later sediments at several 
horizons, but they are mainly in off-shore or quiet water for¬ 
mations and not near shore as these are. It certainly would 
require for its consummation either a suspension of ordinary 
conditions or a very delicate balance of the upper beds near 
water level. In any event, the existence of erosion is not 
precluded, though it is not very probable. 
From the 'possibility of erosion in most sections, its proba¬ 
bility in jnany sections, and its existence in Millers cove, the 
inference is warranted that erosion occupied the interval be¬ 
tween Knox and Chilhowee. 
VII. (c) The question of the extent of the pre-Knox defor¬ 
mation of the Chilhowee beds is even more uncertain. Such 
deformation seems to exist in Limestone cove, but not in 
Holston mountain. In Dennys mountain it appears to be 
present in one place, though absent in most. In Millers 
cove it did exist and in sufficient amount to show a strong 
compressive force. 
The forces that produce folds may be assumed to be general 
in their nature, as their evidence is general and universal.
