13° on Nov. 13, 2019, the coldest reading for this week of the year since 1935. Next is 17° in 2017.
Gastonville’s center stands about 990 ft above sea level. Within three miles the land runs from 730 ft to 1,270 ft, a difference of 540 ft: hilly country. The highest named summit within 15 miles is Sheppler Hill, about 1,430 ft, 12 miles southeast.
Under the town center the state geologic map shows Monongahela Group (limestone, shale, sandstone), from the Carboniferous, 299 to 324 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 29×. 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, sandstone. Age: Carboniferous, 299 to 324 million years old. About 12 mi of the line.
Shale, clastic. Age: Carboniferous, 299 to 324 million years old. About 5 mi of the line.
Sandstone, shale. Age: Permian, 252 to 299 million years old. About 4 mi of the line.
Sandstone, shale. Age: Carboniferous to Permian, 252 to 324 million years old. About 3 mi of the line.
Sandstone, shale. Age: Permian, 252 to 299 million years old. About 0.3 mi of the line.

A raindrop that lands in Gastonville reaches the Gulf of America by way of Peters Creek, the Monongahela, the Ohio and the Mississippi: about 1,980 river miles.
970 miles of the trip are on the Ohio.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Gastonville; river miles along the main stem, rounded.
Gastonville has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 22° in January. About 41 inches of rain fall in a normal year.
On November 14 Gastonville normally reaches 52° and falls to 36°. The record high is 70°, in 2011; the record low 18°, in 1942. The most rain on this date, 0.54 in, fell in 2011.
