Hamilton’s center stands about 490 ft above sea level. Within three miles the land runs from 380 ft to 720 ft, a difference of 340 ft: rolling country. The highest named summit within 15 miles is Bee Mountain, about 880 ft, 7 miles east-southeast.
Under the town center the state geologic map shows Pottsville Formation (lower part) (sandstone), from the Carboniferous, 299 to 324 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 34×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 10 mi of the line.
Sand. Age: Holocene, less than 12,000 years old. About 8 mi of the line.
Sand, clay. Age: Cretaceous, 66 to 145 million years old. About 4 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 Hamilton reaches Mobile Bay and the Gulf of America by way of the Buttahatchee, the Tombigbee and the Mobile: about 440 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 Hamilton; river miles along the main stem, rounded.
Hamilton has a humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 28° in January. About 62 inches of rain fall in a normal year, with about 1 inch of snow.
