140 FLORIDA GEOLOGICAL SURVEY—FOURTH ANNUAL REPORT. 
I 
sages, limestone springs and natural bridges found over the county. 
Lost Creek, which flows through the north-central portion of this 
county, “sinks” and “rises” forming several natural bridges. Many 
of the streams in the county have no surface outlet but pass into 
the earth through these solution cavities. Wakulla Springs, about 
two and one-half miles northeast of Crawfordville, is one of the 
natural outlets of the deep waters in this county. This spring- 
covers an area of about four acres and is 118 feet deep.* The 
spring is the source of the Wakulla River. 
ELEVATIONS. 
Wakulla county is crossed by two railroads, the Georgia, Florida 
and Alabama Railroad, which passes through the central part of 
the county, and the Seaboard Air Line Railway from Tallahassee to 
St. Marks. St. Marks is given by the Seaboard Air Line as eight 
feet above sea. No other elevations along this line in this county 
are given. 
DRAINAGE. 
The Ocklocknee and Sopchoppy rivers on the west receive the 
surface drainage of this part of the county. The north-central part 
of the county is dotted with many sink holes and solution channels 
through which means surface waters find entrance into the under 
lying porous limestones. The eastern part of the county is drained 
principally by St. Marks, Wakulla and East rivers. 
ARTESIAN WELLS. 
Flowing artesian ^yells have not been obtained in Wakulla 
county. The limestone formations which lie at or near the surface 
in the eastern and northern parts , of the county dip to the south 
and west and are overlaid in the southwestern part of the county 
by later formations. From this fact it is possible that flowing wells 
may be secured in the southwestern part of the county along the 
Ocklocknee River. No record, however, is available of test wells 
in this section.
