19° on Nov. 16, 1940, the coldest reading for this week of the year since 1857. Next is 20° in 1916.
Bostwick’s center stands about 770 ft above sea level. Within three miles the land runs from 610 ft to 790 ft, a difference of 180 ft: gently rolling country. The highest named summit within 15 miles is Alcovy Mountain, about 1,100 ft, 13 miles west.
Under the town center the state geologic map shows Amphibolite/ Mica Schist/ Biotitic Gneiss (amphibolite, mica-schist, biotite-gneiss), from the Precambrian to Paleozoic.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 45×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Gneiss. Age: Precambrian to Paleozoic. About 11 mi of the line.
Gneiss. Age: Precambrian to Paleozoic. About 6 mi of the line.
Amphibolite, biotite-gneiss, mica-schist. Age: Precambrian to Paleozoic. About 5 mi of the line.
Amphibolite, mica-schist, biotite-gneiss. Age: Precambrian to Paleozoic. About 2 mi of the line.
Biotite-gneiss, amphibolite. Age: Precambrian to Paleozoic. About 0.7 mi of the line.
Gneiss, amphibolite. Age: Precambrian to Paleozoic. About 0.5 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 Bostwick reaches the Atlantic Ocean by way of Jacks Creek, the Apalachee, the Oconee and the Altamaha: about 340 river miles.
190 miles of the trip are on the Oconee.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Bostwick; river miles along the main stem, rounded.
Bostwick has a humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 34° in January. About 49 inches of rain fall in a normal year.
On November 14 Bostwick normally reaches 65° and falls to 42°. The record high is 84°, in 1931; the record low 23°, in 2013. The most rain on this date, 1.10 in, fell in 1983.
Normals 1991–2020 and records since 1857 from the Athens Area threaded record (Athens Ben Epps Airport, 18 miles northeast). NOAA, through RCC-ACIS.
