OIL DISTRICTS OF SOUTHERN CALIFORNIA. 
The westward extent of the I vers anticline was not determined, nor 
are its relations to the other folds of the region known. Its general 
trend would carry it toward the mouth of Coldwater Canyon. The 
change in direction exhibited by the numerous folds in this region 
suggests that the Ivers anticline may be continuous with the Cold- 
water anticline, the main curvature taking place at some point 
between the two groups of wells, probably on the slope toward Cold- 
water Canyon. On the other hand, the Ivers anticline may be 
merely a local crumple, one of the many that were evidently formed 
in this region. 
The Ivers wells are four in number, the oldest having been drilled 
about fifteen years. The early production of this well is said to have 
been about 20 barrels per day, but the four wells together at the 
time of the writer’s visit were not producing over 11 barrels. It may 
be added, however, that the condition of the wells was not conducive 
to their maximum possibilities, for they are cleaned only at long inter¬ 
vals. The oil is black and is said to vary slightly in gravity from 
well to well, the average being about 17° B. The depth of the wells 
is reported as between 800 and 1,000 feet. 
Incidentally it was learned that the cost of production for the four 
wells in 1902 was only about $3 per day, including $2.50 wages paid a 
pumper. Eleven barrels of oil per day at 50 cents yielded $5.50, 
indicating a profit of $2.50 per day, or about $75 per month. 
Concerning the extension of the productive area westward along 
this fold there is, of course, a question. Seepages, however, are # 
reported for its entire length, or well down the slope on the east side 
of Sespe Canyon above Devilsgate. 
KENTUCK WELLS. 
The Kentuck wells, in Sespe Canyon, just above the mouth of 
Little Sespe Creek, are unique from the standpoint of their struc¬ 
tural location, for they lie along or in proximity to the axis of a 
syncline, which is, moreover, one of the most prominent in the fields 
north of Santa Clara River. It must be said, however, that the 
region is one of exceedingly sharp compression, and it may be due 
to this that local channels and reservoirs conducive to the accumu¬ 
lation of oil have been formed under what might ordinarily be con¬ 
strued as unfavorable structural conditions. Throughout the Coast 
Range are many instances of oil having been obtained from wells 
drilled in highly crumpled strata. 
The syncline in which the Kentuck wells are located is traceable 
eastward through the summit of Oat Mountain and across Pole 
Canyon to Hopper Canyon, where it perhaps unites with another 
syncline of northeasterly trend, the curvature marking the change 
in direction which is characteristic of all the successive folds encoun-
