152 DALL AND STANLEY-BROWN — APALACHICOLA RIVER GEOLOGY. 



longing to the Chattahoochee formation. This locahty was not visited 

 by us. 



Wileys Landing. — At a place on the left bank of the Flint river a few 

 miles above the Florida boundar}'- line, known as Wileys landing, Pro- 

 fessor Pumpelly states that the contact between the Vicksburg and 

 undisturbed Chattahoochee Miocene may be observed. Unfortunately 

 this interesting locality was missed, owing to a severe storm of wind 

 and rain and the fact that our pilot was not acquainted with the place 

 by that name. 



Old Chattahoochee Landing and Sections. — The first stop of importance 

 was made at old Chattahoochee landing, which is on the Apalachicola 

 river just below the mouth of the Flint and in township 3 north, range 6 

 west, section 5. This was formerly a landing for river steamers, but is 

 now superseded by the landing at the railroad bridge about a mile below. 

 A single house stands on a mound near the river which formerly afforded 

 a village site to the Creek Indians. From the old landing place two 

 roads diverge, one toward the northeast, the other to the southeast. The 

 latter is the older and no longer passable for vehicles, being gullied out 

 by water. Both ascend the bluffs at a short distance from the river and 

 come together on the hills a short distance beyond. A roughly levelled 

 section was taken on each of these roads. 



Sections at Old Chattahoochee Landing. 



1. Reddish sand and gravel, with streaks of clay 20 to 40 feet. 



2. Grajdsh yellow friable marl, with harder layers 20 



3. Greenish clayey marl, very adhesive 2J 



4. Chattahoochee limestone, with fossil casts 4 



5. Talus to water's edge, about 3 



Total thickness , 49J to 69J 



This section was taken on the road running northeast from the landing. 



1. Reddish sands, gravel and clays 15 to 20 feet. 



2. Grayish yellow marl, friable 20 " 



3. Greenish clayey marl, sticky . . 2| " 



4. Talus to water's edge, about 8 " 



Total thickness 30J to 45^ " 



Section number 2 was taken on the road which runs about southeast 

 from the landing. The exposures are mostly in the gullies. 



The fossil-bearing bed is number 4, and contains, among other fossils, 

 echinoids, Pecten (Chipola sp.), Area (like transversa), large solitary 

 coral, Venus penita, Lima (like scabixi), LLemicardiicm,, Ostrea, Loripes,
