Leigh’s center stands about 1,600 ft above sea level. Within three miles the land runs from 1,550 ft to 1,730 ft, a difference of 180 ft: gently rolling country.
Under the town center the state geologic map shows Carlile Shale, from the Late Cretaceous, 66 to 100 million years old.
The section below crosses 3 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.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 12 mi of the line.
Limestone, shale. Age: Late Cretaceous, 66 to 100 million years old. About 10 mi of the line.
Shale, limestone. Age: Late Cretaceous, 66 to 100 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Leigh reaches the Gulf of America by way of West Fork Maple Creek, Maple Creek, the Elkhorn, the Platte, the Missouri and the Mississippi: about 1,890 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 Leigh; river miles along the main stem, rounded.
Leigh has a dry-winter hot-summer continental climate. Summer afternoons average 87° in July; winter nights fall to about 13° in January. A normal year brings about 24 inches of snow; with the rain, that comes to about 29 inches of water.
Normals 1991–2020 and records since 1934 at Howells, 12 miles east. NOAA, through RCC-ACIS.
