Hickory Flat’s center stands about 420 ft above sea level. Within three miles the land runs from 370 ft to 590 ft, a difference of 220 ft: rolling country. The highest named summit within 15 miles is Hunters Hill, about 630 ft, 4 miles north.
Under the town center the state geologic map shows Wilcox formation (sand, clay), from the Eocene, 34 to 56 million years old.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 54×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sand, clay. Age: Eocene, 34 to 56 million years old. About 22 mi of the line.
Clay. Age: Paleocene, 56 to 66 million years old. About 2 mi of the line.

A raindrop that lands in Hickory Flat reaches the Gulf of America by way of Oaklimeter Creek, the Tippah, the Little Tallahatchie, the Tallahatchie, the Yazoo and the Mississippi: about 800 river miles.
450 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Hickory Flat; river miles along the main stem, rounded.
