3° on Nov. 17, 1959, the coldest reading for this week of the year since 1948. Next is 10° in 1986.
Barry’s center stands about 680 ft above sea level. Within three miles the land runs from 550 ft to 760 ft, a difference of 210 ft: rolling country. The highest named summit within 15 miles is The Mound, about 840 ft, 8 miles northeast.
Under the town center the state geologic map shows Meppen Limestone, Fern Glen Formation, and Burlington-Keokuk Limestone, from the Early Mississippian to Middle Mississippian, 331 to 359 million years old.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 44×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone. Age: Early Mississippian to Middle Mississippian, 331 to 359 million years old. About 7 mi of the line.
Sandstone. Age: Late Cretaceous, 72 to 84 million years old. About 7 mi of the line.
Shale, limestone. Age: Late Ordovician, 445 to 454 million years old. About 5 mi of the line.
Shale, sandstone, coal. Age: Middle Pennsylvanian to Late Pennsylvanian, 304 to 315 million years old. About 2 mi of the line.
Limestone, shale. Age: Early Mississippian, 347 to 359 million years old. About 1 mi of the line.
Shale. Age: Middle Devonian to Late Devonian, 359 to 388 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 smaller units along the line are not listed.

A raindrop that lands in Barry reaches the Gulf of America by way of Hadley Creek, the The Sny and the Mississippi: about 1,280 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Barry; river miles along the main stem, rounded.
Barry has a hot-summer humid continental climate. Summer afternoons average 89° in July; winter nights fall to about 21° in January. About 38 inches of rain fall in a normal year.
On November 14 Barry normally reaches 55° and falls to 36°. The record high is 81°, in 1999; the record low 10°, in 1986. The most rain on this date, 0.55 in, fell in 1985.
Normals 1991–2020 and records since 1948 at Saverton Lock And Dam 22, 12 miles west-southwest, 210 ft lower. NOAA, through RCC-ACIS.
