The Brooksville 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.
22° on Nov. 17, 1997, the coldest reading for this week of the year since 1981. Next is 22° in 2013.
Brooksville’s center stands about 290 ft above sea level. Within three miles the land runs from 230 ft to 310 ft, a difference of 80 ft: gently rolling country.
Under the town center the state geologic map shows Demopolis chalk, from the Late Cretaceous, 66 to 100 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.
Chalk. Age: Late Cretaceous, 66 to 100 million years old. About 21 mi of the line.
Sand, clay, limestone. Age: Late Cretaceous, 66 to 100 million years old. About 3 mi of the line.

A raindrop that lands in Brooksville reaches Mobile Bay and the Gulf of America by way of Horse Hunters Creek, the Noxubee, the Tombigbee and the Mobile: about 350 river miles.
220 miles of the trip are on the Tombigbee.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Brooksville; river miles along the main stem, rounded.
