Wausa’s center stands about 1,780 ft above sea level. Within three miles the land runs from 1,710 ft to 1,860 ft, a difference of 150 ft: gently rolling country.
Under the town center the state geologic map shows Pierre Shale, from the Late Cretaceous, 66 to 100 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 54×. 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-mudstone, conglomerate-sandstone. Age: Miocene, 5.3 to 23 million years old. About 14 mi of the line.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 11 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Wausa reaches the Gulf of America by way of the North Fork Elkhorn, the Elkhorn, the Platte, the Missouri and the Mississippi: about 1,980 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 Wausa; river miles along the main stem, rounded.
