SANTA CLARA VALLEY: SESPE FIELDS. 57 
tered from north to south along this gorge. To the west evidences 
of the syncline are to be found almost to Devilsgate, and it is pos¬ 
sible that in this direction the fold is continuous, though in a curved 
line, with that occupying the ridge between Coldwater and Pine 
canyons. The pitch of the axis of this syncline is toward the east, 
the strata becoming successively higher as distance in this direction 
is gained. This fold is the most prominent lying between the main 
Topatopa anticline and the series of folds which pass across the 
outer hills of this mountain mass. 
On account of the unusual structural position of the Kentuck wells 
a sketch of their location with reference to the axis of the syncline 
is given in fig. 6. Although they are identified with the synclinal 
structure it might be said that those on either side of the axis are 
on the corresponding slope of the adjacent anticline, and perhaps

this is the true way in which to regard them. Although the syn¬ 
cline is a prominent fold, it is, nevertheless, like the adjacent Ivers, 
Coldwater, and other anticlines, subordinate to the great anticline 
of the Topatopa Range, and the effect of the local structure may be 
lost in the general position which it occupies on the flanks of the far 
broader fold. It seems to the writer to be only in some such way 
as this that the presence of oil here and elsewhere along the axes of 
minor folds and even faults in this region can be accounted for. 
Incidentally, it is worthy of note that along portions of its length 
this syncline, as well as the adjacent folds, is so compressed that the 
plane of its axis is thrown past the vertical, the strata on both sides 
dipping to the north. In the immediate vicinity of the Kentuck 
wells, however, this overthrow has not taken place.
