of a ridge because of subsequent erosion of gorges just back of its 
face, we may best term it the Chattooga escarpment. 
(4) The Tallulah and other mountain groups, rising sharply above 
the Chattahoochee peneplain level. 
(5) The broad open valleys of the tributaries to the Chattahoochee 
River, located on the Chattahoochee peneplain level, and known 
locally as Deep Creek, Big Hazel Creek, Glade Creek, etc. 
(6) The fairly open valleys of that portion of the Tugaloo River 
and its main branches located on the Tugaloo level, southeast of the 
Chattooga escarpment. 
(7) The deep narrow gorges of the upper Tugaloo headwaters, 
cut down into the Chattooga level to a depth of 500 feet in places, 
and known locally as the Tallulah River, Chattooga River, Panther, 
and Little Panther Creeks, etc. In the bottoms of these gorges are 
numerous falls and rapids, the most noted of which are the Tallulah 
Falls in the gorge of the lower Tallulah River. 
(8) The fairly open valleys of several small streams on the Chatta¬ 
hoochee level, which end abruptly on the brinks of the deep gorges 
above referred to, the streams plunging down 400 or 500 feet to the 
bottom of the gorge below. The upland valleys of these streams 
may properly be termed “hanging valleys.” 
(9) In a more general may, we may note the abrupt right-angled 
bend which the Chattooga-Tugaloo River makes near where the 
Tallulah River empties into it, and the fact that a tributary to the 
Chattahoochee River (Deep Creek) continues the southwesterly 
course followed by the Chattooga before it made its sharp turn to 
the southeast. 
The features just enumerated will be described more fully, in the 
order named. 
(1) The Tugaloo level .— This appears to be the normal develop¬ 
ment of the extensive peneplain known as the Piedmont plateau, 
whose farther extent was outlined in the paragraphs on “General 
physiographic relations.” In this region the peneplain has an ele¬ 
vation of from 800 to 1000 feet above sea level, and slopes gently to 
the southeast. In general, the upland surface is remarkably even, 
although stream erosion has dissected it to some extent since its 
uplift. Breaking from its gorge in the higher level to the northwest, 
the Tugaloo River flows out across this upland surface, cutting a
