5.13 inches of rain fell in two days, the most for this week of the year since records began in 1918. The next wettest, 3.73 inches, fell in 1985.
Soper’s center stands about 540 ft above sea level. Within three miles the land runs from 430 ft to 580 ft, a difference of 150 ft: gently rolling country.
Under the town center the state geologic map shows Weno Clay and Soper Limestone (mudstone, shale, sandstone), from the Early Cretaceous, 100 to 145 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 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: Early Cretaceous, 100 to 145 million years old. About 6 mi of the line.
Sandstone, mudstone. Age: Late Cretaceous, 66 to 100 million years old. About 4 mi of the line.
Mudstone, shale, sandstone. Age: Early Cretaceous, 100 to 145 million years old. About 3 mi of the line.
Limestone, shale, marlstone. Age: Early Cretaceous, 100 to 145 million years old. About 3 mi of the line.
Fine-detrital. Age: Holocene, less than 12,000 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.
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 Soper reaches the Gulf of America by way of Bokchito Creek, Muddy Boggy Creek, the Red River, the Atchafalaya and the Lower Atchafalaya: about 740 river miles.
590 miles of the trip are on the Red River.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Soper; river miles along the main stem, rounded.
Soper has a humid subtropical climate. Summer afternoons average 93° in July; winter nights fall to about 28° in January. About 48 inches of rain fall in a normal year.
On November 14 Soper normally reaches 64° and falls to 39°. The record high is 88°, in 1955; the record low 16°, in 1940. The most rain on this date, 1.42 in, fell in 1926.
Normals 1991–2020 and records since 1918 at Antlers, 14 miles north-northeast. NOAA, through RCC-ACIS.
