18° on Nov. 15, 2014, the coldest reading for this week of the year since 1951. Next is 22° in 1996.
Freeburn’s center stands about 800 ft above sea level. Within three miles the land runs from 720 ft to 1,730 ft, a difference of 1,010 ft: steep hill country. The highest named summit within 15 miles is Dicks Knob, about 2,490 ft, 6 miles southwest.
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 13×. 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, siltstone. Age: Carboniferous, 299 to 324 million years old. About 12 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 10 mi of the line.
Sandstone, shale, siltstone. Age: Carboniferous, 299 to 324 million years old. About 1 mi of the line.
Shale, siltstone. Age: Carboniferous, 299 to 324 million years old. About 0.4 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 Freeburn reaches the Gulf of America by way of Peter Creek, the Tug Fork, the Ohio and the Mississippi: about 1,740 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 Freeburn; river miles along the main stem, rounded.
Freeburn has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 26° in January. A normal year brings about 13 inches of snow; with the rain, that comes to about 48 inches of water.
Normals 1991–2020 and records since 1951 at Williamson, 11 miles northwest, 110 ft lower. NOAA, through RCC-ACIS.
