Evans on the Oil-producing uplift of W. Virginia, 335 
ope. 
To the westward from A, and to the eastward from B, there 
is a somewhat sudden transition from the steep slopes to a com- 
paratively slight inclination of the strata, which continues far 
enough to either side to give an additional outcropping of about 
200 feet, estimated perpendicularly to the strata. 
It is not claimed that these figures are accurate; but if they 
are approximately correct, the rocks on the summit of the anti- 
elinal have been brought up out of place not less than 1100 feet, 
probably as much as 1200 at the highest axial point. This es- 
timate has reference to the place of maximum upheaval, a little 
north of the railroad. 
main uplift. One of these, represented at E, is quite prominent 
and persistent, and in fact constitutes the crown or proper axial 
The most distinctive features of this segment of-the uplift are 
seen in the abrupt change of direction at Band F. The Appa- 
lachian folds farther east, where there was more heating and 
crystallization, exhibit curves rather than angles, even when 
most prominent. But here we find sharp angular points, with 
some arching to either side, but upon the whole partaking rather 
of the character of fractures, and affording numerous crevices 
in the soft and brittle rock. Hence the popular name of “the 
break,” by which this uplift is known, is not altogether inappli- 
eable. There is, however, no actual disruption of the strata, 
and no fault, either at the western angle B, or at the easte: 
angle F. The abruptness of these angles has led some into the 
supposition that the nearly horizontal strata of the inner belt 
are not continuous and identical with the inclined strata to
