The Northlake plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
20° on Nov. 13, 2013, the coldest reading for this week of the year since 1948. Next is 21° in 1997.
Northlake’s center stands about 650 ft above sea level. Within three miles the land runs from 650 ft to 860 ft, a difference of 210 ft: rolling country. The highest named summit within 15 miles is Little Mountain, about 900 ft, 9 miles south.
Under the town center the state geologic map shows Anderson metagabbro, from the Paleozoic, 252 to 542 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 60×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Biotite-gneiss, mica-schist. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 14 mi of the line.
Gneiss. Age: Ordovician, 445 to 487 million years old. About 5 mi of the line.
Metagabbro. Age: Paleozoic, 252 to 542 million years old. About 3 mi of the line.
Gneiss. Age: Ordovician to Silurian, 422 to 487 million years old. About 2 mi of the line.

A raindrop that lands in Northlake reaches the Atlantic Ocean by way of Little Beaverdam Creek and the Savannah: about 310 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Northlake; river miles along the main stem, rounded.
Northlake has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 33° in January. About 46 inches of rain fall in a normal year.
On November 14 Northlake normally reaches 64° and falls to 41°. The record high is 79°, in 2007; the record low 22°, in 2013. The most rain on this date, 1.44 in, fell in 1961.
Normals 1991–2020 and records since 1948 at Anderson Regional Airport, 5 miles south-southwest, 120 ft higher. NOAA, through RCC-ACIS.
