The White Hall 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.
86° on Nov. 11, 2020, the hottest reading for this week of the year since 1872. Next is 85° in 1896.
White Hall’s center stands about 190 ft above sea level. Within three miles the land runs from 120 ft to 240 ft, a difference of 120 ft: gently rolling country. The highest named summit within 15 miles is Mount Baber, about 560 ft, 13 miles south-southwest.
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 55×. 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: Holocene, less than 12,000 years old. About 13 mi of the line.
Chalk. Age: Cretaceous, 66 to 145 million years old. About 5 mi of the line.
Chalk, marl. Age: Cretaceous, 66 to 145 million years old. About 2 mi of the line.
Sand. Age: Pleistocene, less than 2.6 million years old. About 2 mi of the line.

A raindrop that lands in White Hall reaches Mobile Bay and the Gulf of America by way of Big Swamp Creek, the Alabama and the Mobile: about 300 river miles.
240 miles of the trip are on the Alabama.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of White Hall; river miles along the main stem, rounded.
White Hall has a humid subtropical climate. Summer afternoons average 94° in July; winter nights fall to about 36° in January. About 51 inches of rain fall in a normal year.
On November 14 White Hall normally reaches 70° and falls to 43°. The record high is 85°, in 1993; the record low 26°, in 2013. The most rain on this date, 3.25 in, fell in 1921.
