21° on Nov. 13, 2019, the coldest reading for this week of the year since 1908. Next is 23° in 1970.
Tenaha’s center stands about 350 ft above sea level. Within three miles the land runs from 260 ft to 390 ft, a difference of 130 ft: gently rolling country. The highest named summit within 15 miles is Bennett Mountain, about 590 ft, 11 miles southwest.
Under the town center the state geologic map shows Wilcox Group, undivided (mudstone), from the Late Paleocene to Early Eocene, 48 to 59 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 61×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Mudstone. Age: Late Paleocene to Early Eocene, 48 to 59 million years old. About 18 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 5 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million 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 Tenaha reaches the Gulf of America by way of Flat Fork Creek and the Sabine: about 260 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 Tenaha; river miles along the main stem, rounded.
Tenaha has a humid subtropical climate. Summer afternoons average 93° in August; winter nights fall to about 36° in January. About 52 inches of rain fall in a normal year.
On November 14 Tenaha normally reaches 67° and falls to 45°. The record high is 86°, in 1955; the record low 21°, in 2019. The most rain on this date, 1.17 in, fell in 1958.
Normals 1991–2020 and records since 1908 at Carthage, 16 miles north-northwest. NOAA, through RCC-ACIS.
