Starr’s center stands about 770 ft above sea level. Within three miles the land runs from 610 ft to 800 ft, a difference of 190 ft: gently rolling country.
Under the town center the state geologic map shows Gneissic granite of Starr, from the Ordovician to Silurian, 422 to 487 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 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.
Gneiss. Age: Ordovician to Silurian, 422 to 487 million years old. About 11 mi of the line.
Biotite-gneiss, mica-schist. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 9 mi of the line.
Schist, gneiss. Age: Precambrian to Paleozoic. About 2 mi of the line.
Schist, gneiss, amphibolite. Age: Precambrian to Paleozoic. About 2 mi of the line.

A raindrop that lands in Starr reaches the Atlantic Ocean by way of Little Generostee Creek and the Savannah: about 290 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Starr; river miles along the main stem, rounded.
Starr 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 Starr 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.
