87° on Nov. 13, 1955, the hottest reading for this week of the year since 1884. Next is 84° in 1941.
Sulphur Springs’s center stands about 310 ft above sea level. Within three miles the land runs from 250 ft to 390 ft, a difference of 140 ft: gently rolling country.
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.
Coarse-detrital, fine-detrital. Age: Pleistocene, less than 2.6 million years old. About 12 mi of the line.
Marl. Age: Late Eocene, 34 to 38 million years old. About 7 mi of the line.
Coarse-detrital, fine-detrital. Age: Holocene, less than 12,000 years old. About 4 mi of the line.
Coarse-detrital, fine-detrital. Age: Holocene, less than 12,000 years old. About 2 mi of the line.

A raindrop that lands in Sulphur Springs reaches the Gulf of America by way of the Bayou Bartholomew, the Ouachita, the Black River, the Red River, the Atchafalaya and the Lower Atchafalaya: about 710 river miles.
350 miles of the trip are on the Bayou Bartholomew.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Sulphur Springs; river miles along the main stem, rounded.
Sulphur Springs has a humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 34° in January. About 51 inches of rain fall in a normal year.
On November 14 Sulphur Springs normally reaches 63° and falls to 42°. The record high is 87°, in 1955; the record low 19°, in 1907. The most rain on this date, 2.45 in, fell in 1922.
