PETROLEUM POSSIBILITIES OE ELORIDA

VOLUSIA COUNTY 
In the western part of Volusia County, at DeLand and at DeLeon 
Springs, near the St. Johns River, shell marls of Pliocene age are ex¬ 
posed in pits opened for road material. On the Atlantic coast such ex¬ 
posures as are seen indicate Pleistocene at the surface. 
From a well at DeLand, Miocene fossils were recognized by Vaughan 
at a depth of from 54 to 70 feet. At Daytona, on the Atlantic coast, the 
Eocene limestone apparently is reached at a depth of from 125 to 150 
feet. A log of a well at New Smyrna has previously been given. (See 
Daytona Area.) 
WAKULLA COUNTY 
Wakulla County borders the Gulf of Mexico and lies east of the Ock- 
locknee River. The eastern half of this county shows chiefly exposures 
of the Chattahoochee formation (Oligocene). In the western part of 
the county the exposures, as seen on the Ocklocknee and Sopchoppy 
Rivers and their tributaries, are of the Alum Bluff formation (Miocene). 
The dip of the formations in this county as indicated by these exposures 
is west or southwest. Underlying the Chattahoochee limestone is the 
Ocala formation (Eocene), and beneath this is the Lower Cretaceous.' 
A log of a deep well in this county has already been given. (See Talla¬ 
hassee Area.) 
A second well is being drilled by the Bonheur Development Company 
near the site of well No. 1. This well No. 2 was begun about November 
1, 1919. 
WALTON COUNTY 
Walton County extends from the Alabama state line to the Gulf of 
Mexico. Near the north line of the county the Marianna and Ocala 
limestones are locally exposed at the surface. Through the central part 
of the county, near the Louisville and Nashville Railroad, is a belt of 
country containing exposures of the Alum Bluff shell marls (Lower 
Miocene. These marl beds may be seen near Eucheanna, Argyle and 
on Shoal River. In this county, near Red Bay, is found the type local¬ 
ity of the Choctawhatchee formation (Upper Miocene). Near the coast 
the formations are concealed, but are probably of later age than the 
Miocene. 
During 1920 two wells, one about seven miles west of DeFuniak 
Springs and the other about twenty-five miles to the southeast, near
