The Tallulah Falls plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
3.69 inches of rain fell in two days, the most for this week of the year since records began in 1942. The next wettest, 3.65 inches, fell in 2018.
Tallulah Falls’s center stands about 1,770 ft above sea level. Within three miles the land runs from 900 ft to 2,290 ft, a difference of 1,390 ft: steep hill country. The highest named summit within 15 miles is Oakey Mountain, about 3,850 ft, 14 miles north.
Under the town center the state geologic map shows Quartzite, from the Precambrian to Paleozoic.
The section below crosses 6 rock units mapped at the surface.

A raindrop that lands in Tallulah Falls reaches the Atlantic Ocean by way of Black Branch, the Tugaloo and the Savannah: about 340 river miles.

Tallulah Falls has a humid subtropical climate. Summer afternoons average 85° in July; winter nights fall to about 30° in January. About 64 inches of rain fall in a normal year, with about 3 inches of snow.
On November 14 Tallulah Falls normally reaches 61° and falls to 38°. The record high is 80°, in 1985; the record low 20°, in 2019. The most rain on this date, 1.67 in, fell in 1947.
