Tampico’s center stands about 650 ft above sea level. Within three miles the land runs from 610 ft to 660 ft, a difference of 50 ft: nearly flat ground.
Under the town center the state geologic map shows Silurian System undivided (dolostone, limestone), from the Silurian, 422 to 445 million years old.
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, limestone. Age: Silurian, 422 to 445 million years old. About 24 mi of the line.

A raindrop that lands in Tampico reaches the Gulf of America by way of the Rock River and the Mississippi: about 1,510 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Tampico; river miles along the main stem, rounded.
Tampico has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 13° in January. A normal year brings about 36 inches of snow; with the rain, that comes to about 37 inches of water.
On November 14 Tampico normally reaches 48° and falls to 30°. The record high is 74°, in 1999; the record low 0°, in 1996. The most rain on this date, 1.83 in, fell in 1926.
