Bolivar’s center stands about 1,060 ft above sea level. Within three miles the land runs from 940 ft to 1,160 ft, a difference of 220 ft: rolling country. The highest named summit within 15 miles is Blue Mound, about 1,340 ft, 12 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 45×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

A raindrop that lands in Bolivar reaches the Gulf of America by way of Town Branch, Piper Creek, the Pomme de Terre, the Osage, the Missouri and the Mississippi: about 1,550 river miles.
Lake on the way: Pomme de Terre Lake.
1,170 miles of the trip are on the Mississippi.
