Green Prairie’s center stands about 1,160 ft above sea level. Within three miles the land runs from 1,110 ft to 1,220 ft, a difference of 110 ft: gently rolling country.
Under the town center the state geologic map shows Little Falls Formation (schist, slate), from the Paleoproterozoic, 1.6 to 2.5 billion 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 42×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Schist, slate. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 15 mi of the line.
Siltstone, graywacke, slate. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 5 mi of the line.
Volcanic, sedimentary. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 3 mi of the line.
Age: Paleoproterozoic, 1.8 to 2 billion years old. About 0.4 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 Green Prairie reaches the Gulf of America by way of the Mississippi: about 1,950 river miles.
Lake on the way: Lake Pepin.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Green Prairie; river miles along the main stem, rounded.
