Lake Santeetlah’s center stands about 2,070 ft above sea level. Within three miles the land runs from 1,830 ft to 3,770 ft, a difference of 1,940 ft: steep hill country. The highest named summit within 15 miles is Huckleberry Knob, about 5,540 ft, 9 miles west-southwest.
Under the town center the state geologic map shows Ocoee Supergroup, Great Smokey Group; Copperhill Formation (metagraywacke), from the Neoproterozoic, 542 to 1,000 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 6×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Metagraywacke. Age: Neoproterozoic, 542 to 1,000 million years old. About 21 mi of the line.
Slate, phyllite. Age: Neoproterozoic, 542 to 1,000 million years old. About 3 mi of the line.
Graywacke. Age: Precambrian. About 0.4 mi of the line.

A raindrop that lands in Lake Santeetlah reaches the Gulf of America by way of Santeetlah Lake, the Cheoah, the Tennessee, the Ohio and the Mississippi: about 1,670 river miles.
Lakes on the way: Guntersville Lake, White Lake (historical), Pickwick Lake and Cummings Lake.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lake Santeetlah; river miles along the main stem, rounded.
