Amherstdale’s center stands about 1,010 ft above sea level. Within three miles the land runs from 900 ft to 2,240 ft, a difference of 1,340 ft: steep hill country. The highest named summit within 15 miles is Kopperston Mountain, about 3,250 ft, 14 miles east.
Under the town center the state geologic map shows Kanawha Formation (sandstone), from the Carboniferous, 299 to 324 million years old.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 9×. 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. Age: Carboniferous, 299 to 324 million years old. About 24 mi of the line.
Sandstone, siltstone, shale. Age: Carboniferous, 299 to 324 million years old. About 0.6 mi of the line.

A raindrop that lands in Amherstdale reaches the Gulf of America by way of Buffalo Creek, the Guyandotte, the Ohio and the Mississippi: about 1,740 river miles.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Amherstdale; river miles along the main stem, rounded.
Amherstdale has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 26° in January. About 49 inches of rain fall in a normal year.
On November 14 Amherstdale normally reaches 59° and falls to 36°. The record high is 83°, in 1909; the record low 14°, in 1986. The most rain on this date, 0.70 in, fell in 1945.
Normals 1991–2020 and records since 1901 at Logan, 11 miles west-northwest, 340 ft lower. NOAA, through RCC-ACIS.
