PETROLEUM POSSIBILITIES OE FLORIDA

at a depth of approximately 500 feet. Record has already been given 
(see Jacksonville Area) of a well at Jacksonville drilled to 980 feet. In 
this well the last 160 feet or more, according to Cushman, is Cretaceous. 
ESCAMBIA COUNTY 
Escambia County is the westernmost county of Florida. It has been 
shown that in Walton and Okaloosa Counties in Florida, and in south¬ 
ern Alabama, there is a pronounced southwest dip in the formations, 
and that the limestones which are found at the surface in the northern 
part of Walton County are buried to an undetermined depth at Pensa¬ 
cola. The surface formations in the southern part of this county are 
later than the Miocene, but otherwise undetermined as to age. The log 
of a deep well at Pensacola has already been given (see Pensacola Area). 
FLAGLER COUNTY 
Flagler County, on the Atlantic coast of Florida, includes mostly level 
lands, with few surface exposures. At the eastern margin of this county 
are found shell marls of Pleistocene age. Wells in this county pass 
through deposits below the surface, probably of Miocene age. At Orange 
Mills, in Putnam County, the Eocene lies at a depth of only 110 feet 
from the surface. It is probable, therefore, that in Flagler County 
these formations lie at no great depth. 
Franklin county 
Franklin County borders the Gulf of Mexico and lies between the 
Apalachicola and Ocklocknee Rivers. Its location is thus at the south 
side of the Quincy Area, elsewhere described, and southwest of the Tal¬ 
lahassee Area. From its location it is probable that the formations dip 
to the south or southwest. At the extreme northeast boundary of the 
county the Tower Miocene formations are probably at or very near the 
surface. To the west and southwest from this place these formations 
lie below the surface. Owing to the prevailingly level surface, but few 
exposures are seen. On New River, at Knox Still Landing, about fif¬ 
teen miles by water from Carrabelle, will be found an exposure of lime¬ 
stone or marl, from which a small collection of fossils was obtained by 
the writer in 1915. These fossils have been identified by T. W. Vaughan, 
of the U. S. Geological Survey, as representing either Miocene or Plio¬ 
cene. 1
