Williamsburg’s center stands about 1,140 ft above sea level. Within three miles the land runs from 1,000 ft to 1,180 ft, a difference of 180 ft: gently rolling country.
Under the town center the state geologic map shows Shawnee Group (limestone, shale), from the Carboniferous, 299 to 324 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 62×. 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. Age: Carboniferous, 299 to 324 million years old. About 17 mi of the line.
Shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 4 mi of the line.
Sand, silt, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 3 mi of the line.

A raindrop that lands in Williamsburg reaches the Gulf of America by way of Mill Creek, Tequa Creek, the Marais des Cygnes, the Osage, the Missouri and the Mississippi: about 1,750 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 Williamsburg; river miles along the main stem, rounded.
Williamsburg has a hot-summer humid continental climate. Summer afternoons average 90° in July; winter nights fall to about 22° in January. About 39 inches of rain fall in a normal year.
