Libertyville’s center stands about 760 ft above sea level. Within three miles the land runs from 660 ft to 770 ft, a difference of 110 ft: gently rolling country.
Under the town center the state geologic map shows Lower Cherokee Group and Raccoon Creek Group (shale, sandstone, siltstone), from the Early Pennsylvanian to Middle Pennsylvanian, 307 to 324 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 64×. 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, siltstone. Age: Early Pennsylvanian to Middle Pennsylvanian, 307 to 324 million years old. About 20 mi of the line.
Dolostone, limestone. Age: Middle Mississippian to Late Mississippian, 324 to 347 million years old. About 4 mi of the line.

A raindrop that lands in Libertyville reaches the Gulf of America by way of East Branch Lick Creek, Lick Creek, the Des Moines and the Mississippi: about 1,410 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Libertyville; river miles along the main stem, rounded.
Libertyville has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 14° in January. A normal year brings about 22 inches of snow; with the rain, that comes to about 38 inches of water.
On November 14 Libertyville normally reaches 48° and falls to 30°. The record high is 75°, in 1958; the record low 3°, in 1940. The most rain on this date, 1.00 in, fell in 1968.
