Princeton’s center stands about 480 ft above sea level. Within three miles the land runs from 410 ft to 670 ft, a difference of 260 ft: rolling country. The highest named summit within 15 miles is Jackson Knob, about 820 ft, 15 miles northwest.
Under the town center the state geologic map shows Ste. Genevieve and St. Louis Limestones, undivided, from the Carboniferous, 324 to 359 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 50×. 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 13 mi of the line.
Limestone, sandstone. Age: Carboniferous, 324 to 359 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 Princeton reaches the Gulf of America by way of Eddy Creek, the Cumberland, the Ohio and the Mississippi: about 1,090 river miles.
Lake on the way: Bards Lake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Princeton; river miles along the main stem, rounded.
