The Sarah Ann 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.
14° on Nov. 14, 1986, the coldest reading for this week of the year since 1901. Next is 16° in 2019.
Sarah Ann’s center stands about 1,160 ft above sea level. Within three miles the land runs from 970 ft to 2,240 ft, a difference of 1,270 ft: steep hill country. The highest named summit within 15 miles is Horsepen Mountain, about 2,490 ft, 5 miles south.
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 11×. 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.
Shale, siltstone. Age: Carboniferous, 299 to 324 million years old. About 0.6 mi of the line.

A raindrop that lands in Sarah Ann reaches the Gulf of America by way of Island Creek, the Guyandotte, the Ohio and the Mississippi: about 1,730 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 Sarah Ann; river miles along the main stem, rounded.
Sarah Ann 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 Sarah Ann 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.
