23° on Nov. 13, 2019, the coldest reading for this week of the year since 1996. Next is 24° in 2013.
Hoschton’s center stands about 920 ft above sea level. Within three miles the land runs from 770 ft to 1,000 ft, a difference of 230 ft: rolling country. The highest named summit within 15 miles is Price Mountain, about 1,220 ft, 5 miles north.
Under the town center the state geologic map shows Granite Gneiss/ Amphibolite (gneiss, amphibolite), from the Precambrian to Paleozoic.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 33×. 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 9 mi of the line.
Gneiss, mica-schist, amphibolite. Age: Precambrian to Paleozoic. About 4 mi of the line.
Gneiss, amphibolite. Age: Precambrian to Paleozoic. About 3 mi of the line.
Metagraywacke, mica-schist. Age: Precambrian to Paleozoic. About 3 mi of the line.
Gneiss. Age: Precambrian to Paleozoic. About 2 mi of the line.
Mica-schist, quartzite, gneiss. Age: Precambrian to Paleozoic. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 smaller units along the line are not listed.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Hoschton reaches the Atlantic Ocean by way of the Mulberry, the Middle Oconee, the Oconee and the Altamaha: about 390 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 Hoschton; river miles along the main stem, rounded.
Hoschton has a humid subtropical climate. Summer afternoons average 88° in July; winter nights fall to about 34° in January. About 52 inches of rain fall in a normal year.
Normals 1991–2020 and records since 1996 at Gainesville Lee Gilmer Memorial Airport, 13 miles north-northwest, 350 ft higher. NOAA, through RCC-ACIS.
