85° on Nov. 17, 1958, the hottest reading for this week of the year since 1890. Next is 83° in 1909.
Hickman’s center stands about 540 ft above sea level. Within three miles the land runs from 490 ft to 1,050 ft, a difference of 560 ft: hilly country. The highest named summit within 15 miles is Mount Defiance, about 1,360 ft, 13 miles west-southwest.
Under the town center the state geologic map shows Nashville Group; Bigby-Cannon Limestone and Hermitage Formation (limestone, calcarenite), from the Ordovician, 445 to 487 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 28×. 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, calcarenite. Age: Ordovician, 445 to 487 million years old. About 11 mi of the line.
Limestone. Age: Ordovician, 445 to 487 million years old. About 4 mi of the line.
Chert. Age: Carboniferous, 324 to 359 million years old. About 4 mi of the line.
Fine-detrital, coarse-detrital. Age: Quaternary, less than 2.6 million years old. About 3 mi of the line.
Shale, limestone. Age: Ordovician, 445 to 487 million years old. About 2 mi of the line.
Limestone. Age: Ordovician, 445 to 487 million years old. About 0.9 mi of the line.

A raindrop that lands in Hickman reaches the Gulf of America by way of Hickman Creek, the Caney Fork, the Cumberland, the Ohio and the Mississippi: about 1,350 river miles.
Lake on the way: Bards Lake.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Hickman; river miles along the main stem, rounded.
Hickman has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 27° in January. About 52 inches of rain fall in a normal year, with about 2 inches of snow.
On November 14 Hickman normally reaches 62° and falls to 36°. The record high is 82°, in 1909; the record low 17°, in 2012. The most rain on this date, 2.50 in, fell in 1915.
