The Thackerville plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
17° on Nov. 12, 2019, the coldest reading for this week of the year since 1987. Next is 20° in 2014.
Thackerville’s center stands about 860 ft above sea level. Within three miles the land runs from 640 ft to 890 ft, a difference of 250 ft: rolling country.
Under the town center the state geologic map shows Terrace Deposits (coarse-detrital, fine-detrital), from the Pleistocene, less than 2.6 million years old.
The section below crosses 10 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.
Coarse-detrital, fine-detrital. Age: Pleistocene, less than 2.6 million years old. About 5 mi of the line.
Clay. Age: Early Cretaceous, 100 to 145 million years old. About 4 mi of the line.
Limestone. Age: Early Cretaceous, 100 to 113 million years old. About 3 mi of the line.
Sandstone-mudstone. Age: Late Cretaceous, 66 to 100 million years old. About 2 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 2 mi of the line.
Limestone. Age: Early Cretaceous, 100 to 145 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 4 smaller units along the line are not listed.

A raindrop that lands in Thackerville reaches the Gulf of America by way of the Red River, the Atchafalaya and the Lower Atchafalaya: about 880 river miles.
740 miles of the trip are on the Red River.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Thackerville; river miles along the main stem, rounded.
Thackerville has a humid subtropical climate. Summer afternoons average 94° in July; winter nights fall to about 32° in January. About 43 inches of rain fall in a normal year, with about 3 inches of snow.
On November 14 Thackerville normally reaches 64° and falls to 43°. The record high is 84°, in 1999; the record low 21°, in 2014. The most rain on this date, 0.89 in, fell in 1993.
