Hallsburg’s center stands about 500 ft above sea level. Within three miles the land runs from 390 ft to 550 ft, a difference of 160 ft: gently rolling country.
Under the town center the state geologic map shows Wolfe City Formation (sandstone-mudstone), from the Late Cretaceous, 66 to 72 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 62×. 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-mudstone. Age: Late Cretaceous, 66 to 72 million years old. About 12 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 6 mi of the line.
Claystone. Age: Late Cretaceous, 66 to 72 million years old. About 4 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.6 mi of the line.

A raindrop that lands in Hallsburg reaches the Gulf of America by way of Shaw Creek and the Brazos: about 410 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Hallsburg; river miles along the main stem, rounded.
Hallsburg has a humid subtropical climate. Summer afternoons average 97° in July; winter nights fall to about 36° in January. About 36 inches of rain fall in a normal year.
