84° on Nov. 12, 2002, the hottest reading for this week of the year since 1938. Next is 83° in 1964.
Gattman’s center stands about 310 ft above sea level. Within three miles the land runs from 260 ft to 480 ft, a difference of 220 ft: rolling country.
Under the town center the state geologic map shows Eutaw formation (sand, clay), from the Late Cretaceous, 66 to 100 million years old.
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 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.
Sand. Age: Holocene, less than 12,000 years old. About 9 mi of the line.
Sand, clay. Age: Late Cretaceous, 66 to 100 million years old. About 8 mi of the line.
Sand, clay. Age: Late Cretaceous, 66 to 100 million years old. About 5 mi of the line.
Sand, clay. Age: Cretaceous, 66 to 145 million years old. About 3 mi of the line.

A raindrop that lands in Gattman reaches Mobile Bay and the Gulf of America by way of the Buttahatchee, the Tombigbee and the Mobile: about 400 river miles.
310 miles of the trip are on the Tombigbee.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Gattman; river miles along the main stem, rounded.
Gattman has a humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 33° in January. About 58 inches of rain fall in a normal year.
On November 14 Gattman normally reaches 66° and falls to 42°. The record high is 80°, in 1964; the record low 20°, in 1963. The most rain on this date, 2.36 in, fell in 1961.
Normals 1991–2020 and records since 1938 at Vernon, 12 miles south-southeast. NOAA, through RCC-ACIS.
