Collins’s center stands about 240 ft above sea level. Within three miles the land runs from 160 ft to 260 ft, a difference of 100 ft: gently rolling country.
Under the town center the state geologic map shows Neogene undifferentiated (sandstone, claystone), from the Tertiary Neogene, 2.6 to 23 million years old.
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 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone, claystone. Age: Tertiary Neogene, 2.6 to 23 million years old. About 23 mi of the line.
Sand. Age: Quaternary, less than 2.6 million years old. About 0.5 mi of the line.
Sand, gravel. Age: Pliocene to Pleistocene, less than 5.3 million years old. About 0.3 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 Collins reaches the Atlantic Ocean by way of Thomas Creek, the Ohoopee and the Altamaha: about 120 river miles.
90 miles of the trip are on the Altamaha.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Collins; river miles along the main stem, rounded.
Collins has a humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 37° in January. About 50 inches of rain fall in a normal year.
On November 14 Collins normally reaches 70° and falls to 46°. The record high is 85°, in 1916; the record low 29°, in 1906. The most rain on this date, 1.45 in, fell in 2008.
Normals 1991–2020 and records since 1904 at Glennville 3 NW, 16 miles southeast. NOAA, through RCC-ACIS.
