Holcomb’s center stands about 180 ft above sea level. Within three miles the land runs from 150 ft to 330 ft, a difference of 180 ft: gently rolling country. The highest named summit within 15 miles is Little Mountain, about 510 ft, 14 miles east.
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 59×. 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 10 mi of the line.
Clay, sand. Age: Eocene, 34 to 56 million years old. About 9 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 5 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Holcomb reaches the Gulf of America by way of the Yalobusha, the Yazoo and the Mississippi: about 650 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 Holcomb; river miles along the main stem, rounded.
Holcomb has a humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 35° in January. About 52 inches of rain fall in a normal year.
On November 14 Holcomb normally reaches 66° and falls to 42°. The record high is 86°, in 1955; the record low 21°, in 2014. The most rain on this date, 2.67 in, fell in 1998.
Normals 1991–2020 and records since 1948 from the Greenwood Area threaded record (Greenwood Leflore Airport, 20 miles south-southwest). NOAA, through RCC-ACIS.
