Pulaski’s center stands about 840 ft above sea level. Within three miles the land runs from 730 ft to 850 ft, a difference of 120 ft: gently rolling country.
Under the town center the state geologic map shows Lower Cherokee Group and Raccoon Creek Group (shale, sandstone, siltstone), from the Early Pennsylvanian to Middle Pennsylvanian, 307 to 324 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.
Shale, sandstone, siltstone. Age: Early Pennsylvanian to Middle Pennsylvanian, 307 to 324 million years old. About 18 mi of the line.
Dolostone, limestone. Age: Middle Mississippian to Late Mississippian, 324 to 347 million years old. About 6 mi of the line.

A raindrop that lands in Pulaski reaches the Gulf of America by way of the Little Fox, the Fox River and the Mississippi: about 1,390 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Pulaski; river miles along the main stem, rounded.
Pulaski has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 14° in January. A normal year brings about 23 inches of snow; with the rain, that comes to about 40 inches of water.
On November 14 Pulaski normally reaches 50° and falls to 30°. The record high is 75°, in 1990; the record low 8°, in 1959. The most rain on this date, 1.32 in, fell in 1931.
Normals 1991–2020 and records since 1893 at Keosauqua, 17 miles east-northeast, 170 ft lower. NOAA, through RCC-ACIS.
