Turin’s center stands about 1,060 ft above sea level. Within three miles the land runs from 1,030 ft to 1,340 ft, a difference of 310 ft: rolling country. The highest named summit within 15 miles is Granger Hill, about 1,400 ft, 5 miles east-northeast.
Under the town center the state geologic map shows Dakata and Windrow Formations (sandstone, shale), from the Early Cretaceous to Late Cretaceous, 94 to 113 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 48×. 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, shale. Age: Early Cretaceous to Late Cretaceous, 94 to 113 million years old. About 9 mi of the line.
Shale, sandstone, siltstone. Age: Early Pennsylvanian to Middle Pennsylvanian, 307 to 324 million years old. About 8 mi of the line.
Shale, limestone. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Shale, limestone. Age: Middle Pennsylvanian, 307 to 315 million years old. About 2 mi of the line.
Shale, siltstone. Age: Middle Pennsylvanian, 307 to 315 million years old. About 2 mi of the line.

A raindrop that lands in Turin reaches the Gulf of America by way of the Little Sioux, the Missouri and the Mississippi: about 1,840 river miles.
1,170 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Turin; river miles along the main stem, rounded.
Turin has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 9° in January. A normal year brings about 31 inches of snow; with the rain, that comes to about 32 inches of water.
On November 14 Turin normally reaches 47° and falls to 25°. The record high is 72°, in 1990; the record low −13°, in 1959. The most rain on this date, 0.73 in, fell in 2024.
Normals 1991–2020 and records since 1937 at Mapleton No.2, 16 miles northeast, 120 ft higher. NOAA, through RCC-ACIS.
