19° on Nov. 16, 1940, the coldest reading for this week of the year since 1857. Next is 20° in 1916.
Arcade’s center stands about 890 ft above sea level. Within three miles the land runs from 690 ft to 910 ft, a difference of 220 ft: rolling country. The highest named summit within 15 miles is Price Mountain, about 1,220 ft, 13 miles west-northwest.
Under the town center the state geologic map shows Biotitic Gneiss / Mica Schist/ Amphibolite (amphibolite, biotite-gneiss, mica-schist), from the Precambrian to Paleozoic.
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 51×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Amphibolite, biotite-gneiss, mica-schist. Age: Precambrian to Paleozoic. About 14 mi of the line.
Gneiss. Age: Precambrian to Paleozoic. About 8 mi of the line.
Gneiss. Age: Precambrian to Paleozoic. About 3 mi of the line.

A raindrop that lands in Arcade reaches the Atlantic Ocean by way of Curry Creek, the North Oconee, the Oconee and the Altamaha: about 370 river miles.
210 miles of the trip are on the Oconee.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Arcade; river miles along the main stem, rounded.
