JEFFERSON COUNTY. 
LOCATION AND SURFACE FEATURES. 
Jefferson county extends from the Georgia-Florida line on the 
north to the Gulf of Mexico on the south. The Aucilla River forms 
most of its eastern boundary, separating it from Madison and 
Taylor counties. Leon and Wakulla counties bound it on the west. 
The total area is 593 square miles or 379,520 acres. 
The general surface features, soils and drainage of Jefferson 
county have much in common with the adjoining counties on the 
east and west. Approximately two-thirds of the county, the 
northern part, consists of the rolling red clay hill type of 
country, while the southern part consists of more level land. This 
northern portion is interspersed with several lakes, the largest of 
which is Lake Miccosukee in the northwest corner. This lake 
receives a large part of the run-off of this section. It is drained 
through solution cavities into the porous limestones which lie com¬ 
paratively close to the surface over most of the county. Many 
limestone sinks occur throughout the county and the Aucilla River 
on the east has a succession of “sinks” and “rises” throughout its 
course. 
ELEVATIONS. 
Although no exact levels have been made in Jefferson county 
the several railroad surveys that have been made give approximate¬ 
ly the elevations of the leading towns. The following are given 
for towns on the Seaboard Air Line: Aucilla 86 feet; Drifton 133 
feet; Lloyds 85 feet. Wacissa, in the south-central part of the 
county, is said to be 45 feet above sea.* According to levels made 
by the Atlantic Coast Line Railroad the depot at Monticello is 202 
feet above sea. 
The two largest streams in the county are the Aucilla River 
on the east and the Wacissa River in the southern part. These
