3.17 inches of rain fell in two days, the most for this week of the year since records began in 1893. The next wettest, 2.15 inches, fell in 1926.
Wellsburg’s center stands about 850 ft above sea level. Within three miles the land runs from 810 ft to 1,770 ft, a difference of 960 ft: steep hill country. The highest named summit within 15 miles is Mount Pisgah, about 2,300 ft, 14 miles south.
Under the town center the state geologic map shows Gardeau Formation (shale), from the Late Devonian, 359 to 384 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 17×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale. Age: Late Devonian, 359 to 384 million years old. About 13 mi of the line.
Sandstone, siltstone, mudstone. Age: Late Devonian, 359 to 384 million years old. About 10 mi of the line.
Sandstone. Age: Late Devonian, 359 to 384 million years old. About 0.8 mi of the line.
Shale, sandstone, conglomerate. Age: Late Devonian, 359 to 384 million years old. About 0.8 mi of the line.

A raindrop that lands in Wellsburg reaches Chesapeake Bay and the Atlantic Ocean by way of the Chemung and the Susquehanna: about 310 river miles.
Lake on the way: Lake Aldred.
250 miles of the trip are on the Susquehanna.

Wellsburg has a warm-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 16° in January. A normal year brings about 42 inches of snow; with the rain, that comes to about 38 inches of water.
On November 14 Wellsburg normally reaches 49° and falls to 30°. The record high is 75°, in 1902; the record low 10°, in 1905. The most rain on this date, 0.85 in, fell in 1929.
