WATER SUPPLY OF WEST FLORIDA. 
WALTON COUNTY. 
LOCATION AND SURFACE FEATURES. 
Walton county extends from the State line to the Gulf. Holmes 
and Washington counties form ^astern boundary, while on its 
west is Santa Rosa county. The area is 1384 square miles or 
885,760 acres. 
The northwestern and northern parts of the county consist of a 
rolling type of country with a sandy soil and clay sub-soil. In the 
more hilly sections the yellowish and reddish sandy clays are ex¬ 
posed at the surface resembling the red hills so characteristic in 
other sections of the State. Within this northern area at Natural 
Bridge on Natural Bridge Creek is an exposure of a soft fine grain¬ 
ed limestone. Other natural bridges and sinks also occur along 
this creek. The limestone exposed in this part of the county be¬ 
longs to the Vicksburg formation.* The native growth immediately 
along the streams in the limestone section consists principally of 
water oak, hickory, dog wood and cedar. Some short leaf pine 
and cypress was also seen. This is the westernmost county in the 
State in which limestone lies at or close enough to the surface tov 
have any influence on the general surface features. 
Running practically across this county from west to east along 
or near the Louisville and Nashville Railroad is a very sandy ridge 
supporting a growth of dwarf oak. The ridge is three or four miles 
wide and lies on the divide between the territory tributary to the 
Yellow River and the territory draining through numerous small 
streams to the Gulf. The southern part of the county bordering the 
Choctawhatchee Bay is chiefly open pine land. 
Euchee Valley is a characteristic small area lying in the eastern 
part of the county. This so-called valley is in reality the transition 
ground between uplands of the interior of the county and the valley 
of the Choctawhatchee River. It lies chiefly on the north side of 
Goose Creek and the west side of Sandy Creek, and consists of a suc¬ 
cession of small hills giving a decidedly rolling topography. The 
hills of which Mossy Hill is the best known are outliers from the 
plateau section of the county. The forest growth includes hardwood 
and short leaf pine hammock. The clay sub-soil on the slopes lies 
usually near the surface. In many ways this valley resembles 
Holmes Valley on the opposite side of the Choctawhatchee River, 
both having been formed by the same processes.
