Olive Branch’s center stands about 380 ft above sea level. Within three miles the land runs from 310 ft to 420 ft, a difference of 110 ft: gently rolling country.
Under the town center the state geologic map shows Kosciusko formation (sand, clay), from the Eocene, 34 to 56 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 64×. 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 16 mi of the line.
Silt. Age: Quaternary, less than 2.6 million years old. About 6 mi of the line.
Claystone, clay. Age: Eocene, 34 to 56 million years old. About 2 mi of the line.

A raindrop that lands in Olive Branch reaches the Gulf of America by way of Camp Creek, the Coldwater, the Tallahatchie, the Yazoo and the Mississippi: about 810 river miles.
Lake on the way: Arkabutla Lake.
450 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Olive Branch; river miles along the main stem, rounded.
Olive Branch has a humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 33° in January. About 55 inches of rain fall in a normal year, with about 3 inches of snow.
On November 14 Olive Branch normally reaches 63° and falls to 43°. The record high is 81°, in 1999; the record low 20°, in 1940. The most rain on this date, 3.17 in, fell in 1915.
