Carlton’s center stands about 180 ft above sea level. Within three miles the land runs from 20 ft to 230 ft, a difference of 210 ft: rolling country. The highest named summit within 15 miles is Roundtop Hill, about 410 ft, 9 miles north.
Under the town center the state geologic map shows Miocene Series undifferentiated (sand, clay), from the Miocene to Pliocene, 2.6 to 23 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 48×. 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. Age: Holocene, less than 12,000 years old. About 12 mi of the line.
Sand, clay. Age: Miocene to Pliocene, 2.6 to 23 million years old. About 9 mi of the line.
Sand. Age: Eocene, 34 to 56 million years old. About 2 mi of the line.
Clay, limestone. Age: Eocene, 34 to 56 million years old. About 0.4 mi of the line.
Limestone. Age: Oligocene, 23 to 34 million years old. About 0.4 mi of the line.

A raindrop that lands in Carlton reaches Mobile Bay and the Gulf of America by way of Sand Hill Creek, the Tombigbee and the Mobile: about 85 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Carlton; river miles along the main stem, rounded.
Carlton has a humid subtropical climate. Summer afternoons average 91° in July; winter nights fall to about 36° in January. About 60 inches of rain fall in a normal year.
On November 14 Carlton normally reaches 69° and falls to 43°. The record high is 84°, in 1993; the record low 26°, in 2013. The most rain on this date, 2.00 in, fell in 1961.
Normals 1991–2020 and records since 1961 at Jackson, 13 miles north-northwest. NOAA, through RCC-ACIS.
