The Marbury 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.
84° on Nov. 17, 1957, the hottest reading for this week of the year since 1893. Next is 83° in 1924.
Marbury’s center stands about 520 ft above sea level. Within three miles the land runs from 400 ft to 670 ft, a difference of 270 ft: rolling country.
Under the town center the state geologic map shows Tuscaloosa Group; Coker Formation (sand, clay), from the Cretaceous, 66 to 145 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 41×. 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: Cretaceous, 66 to 145 million years old. About 12 mi of the line.
Sand. Age: Holocene, less than 12,000 years old. About 5 mi of the line.
Sand, clay. Age: Cretaceous, 66 to 145 million years old. About 4 mi of the line.
Sand. Age: Pleistocene, less than 2.6 million years old. About 1 mi of the line.

A raindrop that lands in Marbury reaches Mobile Bay and the Gulf of America by way of Mortar Creek, the Coosa, the Alabama and the Mobile: about 380 river miles.
310 miles of the trip are on the Alabama.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Marbury; river miles along the main stem, rounded.
Marbury has a humid subtropical climate. Summer afternoons average 91° in July; winter nights fall to about 33° in January. About 60 inches of rain fall in a normal year.
On November 14 Marbury normally reaches 66° and falls to 41°. The record high is 81°, in 1944; the record low 21°, in 2019. The most rain on this date, 1.95 in, fell in 1972.
