17° on Nov. 16, 2019, the coldest reading for this week of the year since 1893. Next is 20° in 1932.
Marshall’s center stands about 410 ft above sea level. Within three miles the land runs from 310 ft to 470 ft, a difference of 160 ft: gently 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 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 58×. 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 10 mi of the line.
Siltstone, sandstone. Age: Middle Eocene, 38 to 48 million years old. About 6 mi of the line.
Sandstone. Age: Eocene, 34 to 56 million years old. About 4 mi of the line.
Sandstone. Age: Eocene, 34 to 56 million years old. About 2 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 1 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.6 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 Marshall reaches the Gulf of America by way of Parker Creek, Eightmile Creek and the Sabine: about 310 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 Marshall; river miles along the main stem, rounded.
Marshall has a humid subtropical climate. Summer afternoons average 94° in July; winter nights fall to about 33° in January. About 51 inches of rain fall in a normal year.
On November 14 Marshall normally reaches 68° and falls to 42°. The record high is 87°, in 1955; the record low 18°, in 2019. The most rain on this date, 1.90 in, fell in 1915.
Normals 1991–2020 and records since 1893 at Marshall, 4 miles south-southeast, 110 ft lower. NOAA, through RCC-ACIS.
