Hawk Point’s center stands about 740 ft above sea level. Within three miles the land runs from 560 ft to 760 ft, a difference of 200 ft: rolling country.
Under the town center the state geologic map shows Osagean Series (limestone), from the Carboniferous, 324 to 359 million years old.
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.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 24 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 Hawk Point reaches the Gulf of America by way of Coon Creek, Big Creek, the Cuivre and the Mississippi: about 1,250 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Hawk Point; river miles along the main stem, rounded.
