The top of the anticline is passed before reaching this section and 
the strata are again dipping slightly to the north of northwest. 
These sections, including the one at Chattahoochee Landing, prove 
the existence of small folds in the limestone the axis of the folds being 
in general northwest to southeast. 
The following section is found on the Chattahoochee-Quincy road 
at the crossing of North Mosquito Creek one mile east of Chattahoo¬

At the crossing of the Seaboard Air Line Railroad on Mosquito 
Creek the following section is seen: 
Thickness 
of stratum. 
3. Pale yellow sandy limestone. 554 feet 
2. Gray sandstone . 224 feet 
1. Covered from the river a distance of 
about one and one-half miles. Base 
of section above the river, about.... 
Height above river 
(stage of Mar. 5,1909). 
1224 to 18 feet. 
10 to 1224 feet.

The gray sandstone at the base of this exposure is topographically 
the lowest member of the Chattahoochee series seen in Florida. It 
lies at this bridge at about ten feet above the river stage of March 5, 
1909; while in the section at Chattahoochee Landing the base of the 
section is 21feet above the river at the same stage.
