Warsaw’s center stands about 1,740 ft above sea level. Within three miles the land runs from 1,450 ft to 1,920 ft, a difference of 470 ft: hilly country. The highest named summit within 15 miles is Edeburn Hill, about 1,950 ft, 8 miles north-northwest.
Under the town center the state geologic map shows Allegheny Formation (sandstone), from the Carboniferous, 299 to 324 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 20×. 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 Warsaw reaches the Gulf of America by way of North Fork Redbank Creek, Redbank Creek, the Allegheny, the Ohio and the Mississippi: about 2,070 river miles.
970 miles of the trip are on the Ohio.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Warsaw; river miles along the main stem, rounded.
Warsaw has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 17° in January. About 42 inches of rain fall in a normal year.
