prominent peaks and ridges exhibit a close correspondence in 
altitude along a northeast southwest direction, with a fairly 
uniform increase in hight from the southeastern foothills to 
the crest of the range. It will also be noticed that the head 
waters of Panther creek, which empties in the Tugaloo a few 
miles below the mouth of the Tallulah, and those of Glade 
creek, a tributary of the Chattahoochee, are within less than 
a mile of each other with a low divide between them. 
The investigations of geologists most familiar with the 
southern Appalachians have shown that the greater portion, 
if not all, of the province has been twice base-leveled — once 
during Cretaceous and once during Tertiary times.* 
In the region around Tallulah falls, however, considerable 
areas seem not to have been reduced to base level and, owing 
to close proximity in altitude and other complicating condi- 
tions, the differentiation of the two peneplains in northeastern 
Georgia is not easy. 
For the last four miles above its confluence with the Chat- 
tooga the Tallulah river cuts through the southeastern side 
of a series of broken ridges called the Tallulah mountains and 
it is here that the gorge and falls of the same name are lo- 
cated. 
In the region of the gorge the river has a normal flow, as 
determined by Mr. B. M. Hall, hydrographer for the U. S. 
Geological Survey, of about i8o cubic feet per second. 
The town of Tallulah Falls is on the western side of the 
river three miles above its mouth and an iron bridge, con- 
venient in locating positions, spans the gorge on the road 
to Clayton, Georgia. 
The gorge begins about a mile and a half above this bridge 
and runs all the way to the mouth of the river. From here 
it may be considered as being continued by the Tugaloo for 
about two miles. 
Above the gorge the Tallulah presents the usual character- 
istics of a rapid flowing mountain stream with steep slopes 
on either side and sufficient valley land at places to afford 
small farm settlements. Below the gorge the Tugaloo pre- 
sents a similar aspect characterized, however, by broader al-
