Overton’s center stands about 490 ft above sea level. Within three miles the land runs from 370 ft to 570 ft, a difference of 200 ft: rolling country.
Under the town center the state geologic map shows Reklaw Formation (sandstone), from the Eocene, 34 to 56 million years old.
The section below crosses 4 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.
Sandstone. Age: Eocene, 34 to 56 million years old. About 13 mi of the line.
Siltstone, sandstone. Age: Middle Eocene, 38 to 48 million years old. About 9 mi of the line.
Sandstone. Age: Eocene, 34 to 56 million years old. About 1 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 0.9 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 Overton reaches the Gulf of America by way of Little Rabbit Creek, Rabbit Creek and the Sabine: about 350 river miles.
Lakes on the way: Toledo Bend Reservoir and Sabine Lake.
140 miles of the trip are on the Sabine.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Overton; river miles along the main stem, rounded.
Overton has a humid subtropical climate. Summer afternoons average 95° in August; winter nights fall to about 37° in January. About 45 inches of rain fall in a normal year.
On November 14 Overton normally reaches 68° and falls to 45°. The record high is 89°, in 1955; the record low 22°, in 1907. The most rain on this date, 1.25 in, fell in 1970.
Normals 1991–2020 and records since 1902 from the Longview Area threaded record (Longview E Tx Regional Airport, 17 miles east-northeast, 140 ft lower). NOAA, through RCC-ACIS.
