20° on Nov. 16, 2019, the coldest reading for this week of the year since 1961. Next is 25° in 1997.
St. Stephens’s center stands about 100 ft above sea level. Within three miles the land runs from 0 ft to 260 ft, a difference of 260 ft: rolling country. The highest named summit within 15 miles is Roundtop Hill, about 410 ft, 13 miles east-southeast.
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 44×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sand, clay. Age: Miocene to Pliocene, 2.6 to 23 million years old. About 13 mi of the line.
Sand. Age: Holocene, less than 12,000 years old. About 3 mi of the line.
Limestone. Age: Oligocene, 23 to 34 million years old. About 3 mi of the line.
Sand. Age: Eocene, 34 to 56 million years old. About 3 mi of the line.
Claystone. Age: Eocene, 34 to 56 million years old. About 2 mi of the line.
Clay, limestone. Age: Eocene, 34 to 56 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in St. Stephens reaches Mobile Bay and the Gulf of America by way of the Tombigbee and the Mobile: about 100 river miles.
55 miles of the trip are on the Tombigbee.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of St. Stephens; river miles along the main stem, rounded.
St. Stephens has a humid subtropical climate. Summer afternoons average 91° in July; winter nights fall to about 36° in January. About 60 inches of rain fall in a normal year.
On November 14 St. Stephens normally reaches 69° and falls to 43°. The record high is 84°, in 1993; the record low 26°, in 2013. The most rain on this date, 2.00 in, fell in 1961.
Normals 1991–2020 and records since 1961 at Jackson, 8 miles east-southeast, 120 ft higher. NOAA, through RCC-ACIS.
