The Cobbtown plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
25° on Nov. 13, 2019, the coldest reading for this week of the year since 1945. Next is 26° in 1969.
Cobbtown’s center stands about 190 ft above sea level. Within three miles the land runs from 100 ft to 260 ft, a difference of 160 ft: gently rolling country.
Under the town center the state geologic map shows Citronelle Formation (sand), from the Late Pliocene, 2.6 to 3.6 million years old.
The section below crosses 2 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.
Sand. Age: Late Pliocene, 2.6 to 3.6 million years old. About 23 mi of the line.
Clay, sand. Age: Pleistocene to Holocene, less than 2.6 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 Cobbtown reaches Pensacola Bay and the Gulf of America by way of Blackjack Creek, West Fork Big Coldwater Creek, Big Coldwater Creek and the Blackwater: about 35 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Cobbtown; river miles along the main stem, rounded.
Cobbtown has a humid subtropical climate. Summer afternoons average 91° in July; winter nights fall to about 39° in January. About 63 inches of rain fall in a normal year.
On November 14 Cobbtown normally reaches 71° and falls to 45°. The record high is 84°, in 1985; the record low 30°, in 1969. The most rain on this date, 1.31 in, fell in 1961.
