7° on Nov. 13, 2019, the coldest reading for this week of the year since 1968. Next is 10° in 1986.
Greens Fork’s center stands about 1,010 ft above sea level. Within three miles the land runs from 980 ft to 1,140 ft, a difference of 160 ft: gently rolling country. The highest named summit within 15 miles is Hoosier Hill, about 1,320 ft, 12 miles northeast.
Under the town center the state geologic map shows Dillsboro Formation (limestone, shale), from the Ordovician, 445 to 487 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 46×. 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, shale. Age: Ordovician, 445 to 487 million years old. About 11 mi of the line.
Limestone, shale. Age: Ordovician, 445 to 487 million years old. About 9 mi of the line.
Limestone. Age: Silurian, 422 to 445 million years old. About 4 mi of the line.

A raindrop that lands in Greens Fork reaches the Gulf of America by way of the Greens Fork, the Whitewater, the Great Miami, the Ohio and the Mississippi: about 1,550 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 Greens Fork; river miles along the main stem, rounded.
Greens Fork has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 20° in January. About 43 inches of rain fall in a normal year.
On November 14 Greens Fork normally reaches 52° and falls to 33°. The record high is 74°, in 1971; the record low 10°, in 1986. The most rain on this date, 2.00 in, fell in 1993.
Normals 1991–2020 and records since 1968 at Richmond Water Works, 9 miles east-southeast. NOAA, through RCC-ACIS.
