80° on Nov. 11, 2020, the hottest reading for this week of the year since 1948. Next is 77° in 2010.
Greenville’s center stands about 860 ft above sea level. Within three miles the land runs from 670 ft to 950 ft, a difference of 280 ft: rolling country.
Under the town center the state geologic map shows Sanders Group (limestone), from the Carboniferous, 324 to 359 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 35×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

A raindrop that lands in Greenville reaches the Gulf of America by way of Jersey Park Creek, Indian Creek, the Ohio and the Mississippi: about 1,350 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 Greenville; river miles along the main stem, rounded.
Greenville has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 26° in January. About 48 inches of rain fall in a normal year, with about 4 inches of snow.
