Nehawka’s center stands about 1,000 ft above sea level. Within three miles the land runs from 970 ft to 1,200 ft, a difference of 230 ft: rolling country. The highest named summit within 15 miles is King Hill, about 1,190 ft, 10 miles east-northeast.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 51×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone, shale, siltstone. Age: Carboniferous, 299 to 324 million years old. About 11 mi of the line.
Shale, sandstone, limestone. Age: Carboniferous, 299 to 324 million years old. About 7 mi of the line.
Limestone, shale. Age: Late Pennsylvanian, 299 to 307 million years old. About 2 mi of the line.
Shale, limestone. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.
Shale, mudstone. Age: Late Pennsylvanian, 299 to 307 million years old. About 1 mi of the line.
Shale, mudstone. Age: Late Pennsylvanian, 299 to 307 million years old. About 0.7 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.

A raindrop that lands in Nehawka reaches the Gulf of America by way of Weeping Water Creek, the Missouri and the Mississippi: about 1,740 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 Nehawka; river miles along the main stem, rounded.
Nehawka has a hot-summer humid continental climate. Summer afternoons average 87° in July; winter nights fall to about 14° in January. A normal year brings about 24 inches of snow; with the rain, that comes to about 34 inches of water.
On November 14 Nehawka normally reaches 52° and falls to 30°. The record high is 83°, in 1999; the record low 2°, in 1986. The most rain on this date, 0.83 in, fell in 1972.
Normals 1991–2020 and records since 1933 at Nebraska City 2 NW, 11 miles south-southeast. NOAA, through RCC-ACIS.
