9° on Nov. 13, 2019, the coldest reading for this week of the year since 1897. Next is 10° in 1959.
Anthoston’s center stands about 450 ft above sea level. Within three miles the land runs from 370 ft to 470 ft, a difference of 100 ft: gently rolling country. The highest named summit within 15 miles is Steamport Hill, about 640 ft, 11 miles south.
Under the town center the state geologic map shows Sturgis Formation (siltstone), from the Carboniferous, 299 to 324 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 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.
Siltstone. Age: Carboniferous, 299 to 324 million years old. About 10 mi of the line.
Sand, silt. Age: Pleistocene to Holocene, less than 2.6 million years old. About 8 mi of the line.
Shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 0.7 mi of the line.

A raindrop that lands in Anthoston reaches the Gulf of America by way of Canoe Creek, the Ohio and the Mississippi: about 1,160 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 Anthoston; river miles along the main stem, rounded.
Anthoston has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 25° in January. A normal year brings about 11 inches of snow; with the rain, that comes to about 48 inches of water.
On November 14 Anthoston normally reaches 57° and falls to 37°. The record high is 77°, in 1971; the record low 11°, in 1986. The most rain on this date, 2.40 in, fell in 1993.
