5° on Nov. 13, 2019, the coldest reading for this week of the year since 1887. Next is 7° in 1959.
Sims’s center stands about 430 ft above sea level. Within three miles the land runs from 380 ft to 450 ft, a difference of 70 ft: gently rolling country.
Under the town center the state geologic map shows Mattoon Formation (shale), from the Late Pennsylvanian, 304 to 307 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.
Shale. Age: Late Pennsylvanian, 304 to 307 million years old. About 24 mi of the line.

A raindrop that lands in Sims reaches the Gulf of America by way of the Dry Fork, the Skillet Fork, the Little Wabash, the Ohio and the Mississippi: about 1,190 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 Sims; river miles along the main stem, rounded.
