10° on Nov. 17, 1959, the coldest reading for this week of the year since 1911. Next is 10° in 2019.
Woodlawn’s center stands about 610 ft above sea level. Within three miles the land runs from 560 ft to 860 ft, a difference of 300 ft: rolling country. The highest named summit within 15 miles is Heitsmanns Hill, about 900 ft, 13 miles northwest.
Under the town center the state geologic map shows Kope Formation (shale), from the Middle Ordovician to Late Ordovician, 445 to 471 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 45×. 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, limestone. Age: Late Ordovician, 445 to 459 million years old. About 8 mi of the line.
Shale. Age: Middle Ordovician to Late Ordovician, 445 to 471 million years old. About 7 mi of the line.
Limestone, shale. Age: Late Ordovician, 445 to 459 million years old. About 5 mi of the line.
Shale, limestone. Age: Late Ordovician, 445 to 454 million years old. About 3 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Woodlawn reaches the Gulf of America by way of West Fork Mill Creek, Mill Creek, the Ohio and the Mississippi: about 1,490 river miles.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Woodlawn; river miles along the main stem, rounded.
Woodlawn has a hot-summer humid continental climate. Summer afternoons average 87° in July; winter nights fall to about 21° in January. About 45 inches of rain fall in a normal year.
On November 14 Woodlawn normally reaches 54° and falls to 33°. The record high is 78°, in 1931; the record low 10°, in 2019. The most rain on this date, 1.45 in, fell in 2011.
Normals 1991–2020 and records since 1911 at Fairfield, 9 miles northwest. NOAA, through RCC-ACIS.
