St. Rose’s center stands about 500 ft above sea level. Within three miles the land runs from 450 ft to 520 ft, a difference of 70 ft: gently rolling country.
Under the town center the state geologic map shows Bond Formation (shale, sandstone, limestone), from the Late Pennsylvanian, 304 to 307 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, limestone. Age: Late Pennsylvanian, 304 to 307 million years old. About 14 mi of the line.
Shale, limestone. Age: Late Pennsylvanian, 304 to 307 million years old. About 10 mi of the line.

A raindrop that lands in St. Rose reaches the Gulf of America by way of Lake Branch, Sugar Creek, the Kaskaskia and the Mississippi: about 1,170 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of St. Rose; river miles along the main stem, rounded.
