Floraville’s center stands about 520 ft above sea level. Within three miles the land runs from 450 ft to 580 ft, a difference of 130 ft: gently rolling country. The highest named summit within 15 miles is Potato Hill, about 750 ft, 15 miles west-southwest.
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 59×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale, sandstone. Age: Early Pennsylvanian to Middle Pennsylvanian, 307 to 324 million years old. About 13 mi of the line.
Limestone, sandstone, shale. Age: Middle Mississippian, 331 to 347 million years old. About 6 mi of the line.
Limestone. Age: Middle Mississippian, 331 to 347 million years old. About 4 mi of the line.
Limestone. Age: Middle Mississippian, 331 to 347 million years old. About 1 mi of the line.

A raindrop that lands in Floraville reaches the Gulf of America by way of Prairie du Long Creek, Richland Creek, the Kaskaskia and the Mississippi: about 1,130 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Floraville; river miles along the main stem, rounded.
Floraville has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 24° in January. A normal year brings about 11 inches of snow; with the rain, that comes to about 43 inches of water.
On November 14 Floraville normally reaches 59° and falls to 37°. The record high is 82°, in 1999; the record low 11°, in 1986. The most rain on this date, 3.23 in, fell in 1993.
