Vienna’s center stands about 850 ft above sea level. Within three miles the land runs from 610 ft to 980 ft, a difference of 370 ft: rolling country. The highest named summit within 15 miles is Indian House Mounds, about 1,110 ft, 9 miles east.
Under the town center the state geologic map shows Smithville Dolomite, Powell Dolomite, Cotter Dolomite, Jefferson City Dolomite (dolostone), from the Early Ordovician, 471 to 487 million years old.
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 33×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 14 mi of the line.
Sandstone, chert. Age: Early Ordovician, 471 to 487 million years old. About 7 mi of the line.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 2 mi of the line.
Shale, limestone, sandstone. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.

A raindrop that lands in Vienna reaches the Gulf of America by way of Fly Creek, the Maries, the Osage, the Missouri and the Mississippi: about 1,350 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Vienna; river miles along the main stem, rounded.
Vienna has a hot-summer humid continental climate. Summer afternoons average 88° in July; winter nights fall to about 22° in January. About 43 inches of rain fall in a normal year.
On November 14 Vienna normally reaches 56° and falls to 36°. The record high is 78°, in 2025; the record low 11°, in 2018. The most rain on this date, 2.41 in, fell in 2020.
