Grant’s center stands about 1,230 ft above sea level. Within three miles the land runs from 610 ft to 1,280 ft, a difference of 670 ft: hilly country. The highest named summit within 15 miles is Nat Mountain, about 1,670 ft, 12 miles north.
Under the town center the state geologic map shows Pottsville Formation (sandstone, conglomerate), from the Carboniferous, 299 to 324 million years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 18×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone, dolostone, shale. Age: Carboniferous, 324 to 359 million years old. About 7 mi of the line.
Sandstone, conglomerate. Age: Carboniferous, 299 to 324 million years old. About 7 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 4 mi of the line.
Shale. Age: Carboniferous, 324 to 359 million years old. About 1 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 1 mi of the line.
Sandstone, shale. Age: Silurian, 422 to 445 million years old. About 0.5 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.

A raindrop that lands in Grant reaches the Gulf of America by way of the Paint Rock, the Tennessee, the Ohio and the Mississippi: about 1,370 river miles.
Lakes on the way: Guntersville Lake, White Lake (historical) and Pickwick Lake.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Grant; river miles along the main stem, rounded.
Grant has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 32° in January. About 57 inches of rain fall in a normal year.
On November 14 Grant normally reaches 62° and falls to 43°. The record high is 74°, in 2011; the record low 22°, in 2019. The most rain on this date, 1.27 in, fell in 2024.
Normals 1991–2020 and records since 1995 at Guntersville No.2, 14 miles south-southwest, 640 ft lower. NOAA, through RCC-ACIS.
