Hanson’s center stands about 430 ft above sea level. Within three miles the land runs from 380 ft to 560 ft, a difference of 180 ft: gently rolling country. The highest named summit within 15 miles is Harps Hill, about 670 ft, 13 miles south-southeast.
Under the town center the state geologic map shows Sturgis Formation (siltstone), from the Carboniferous, 299 to 324 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.
Siltstone. Age: Carboniferous, 299 to 324 million years old. About 18 mi of the line.
Sand, silt. Age: Pleistocene to Holocene, less than 2.6 million years old. About 6 mi of the line.

A raindrop that lands in Hanson reaches the Gulf of America by way of Otter Creek, the Pond, the Green River, the Ohio and the Mississippi: about 1,230 river miles.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Hanson; river miles along the main stem, rounded.
Hanson has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 28° in January. About 52 inches of rain fall in a normal year.
On November 14 Hanson normally reaches 59° and falls to 40°. The record high is 77°, in 1990; the record low 12°, in 1986. The most rain on this date, 3.70 in, fell in 1957.
Normals 1991–2020 and records since 1946 at Madisonville, 5 miles south-southwest. NOAA, through RCC-ACIS.
