Warsaw’s center stands about 1,000 ft above sea level. Within three miles the land runs from 960 ft to 1,100 ft, a difference of 140 ft: gently rolling country.
Under the town center the state geologic map shows Lower Ordovician (dolostone, sandstone), from the Early Ordovician, 471 to 487 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.
Dolostone, sandstone. Age: Early Ordovician, 471 to 487 million years old. About 16 mi of the line.
Shale, limestone, sandstone. Age: Middle Ordovician to Late Ordovician, 445 to 471 million years old. About 9 mi of the line.

A raindrop that lands in Warsaw reaches the Gulf of America by way of the Cannon and the Mississippi: about 1,840 river miles.
Lake on the way: Lake Pepin.
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 hot-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 5° in January. A normal year brings about 44 inches of snow; with the rain, that comes to about 36 inches of water.
On November 14 Warsaw normally reaches 42° and falls to 26°. The record high is 71°, in 1999; the record low 5°, in 2014. The most rain on this date, 0.37 in, fell in 1973.
Normals 1991–2020 and records since 1961 at Owatonna, 13 miles southeast, 140 ft higher. NOAA, through RCC-ACIS.
