3.09 inches of rain fell in two days, the most for this week of the year since records began in 1983. The next wettest, 2.79 inches, fell in 2018.
Ben Avon’s center stands about 750 ft above sea level. Within three miles the land runs from 640 ft to 820 ft, a difference of 180 ft: gently rolling country. The highest named summit within 15 miles is Thicketty Mountain, about 1,260 ft, 14 miles north-northeast.
Under the town center the state geologic map shows Reedy River complex (gneiss), from the Paleozoic, 252 to 542 million years old.
The section below crosses 10 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 42×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Biotite-gneiss. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 11 mi of the line.
Granite. Age: Devonian, 359 to 422 million years old. About 4 mi of the line.
Amphibolite. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 2 mi of the line.
Mica-schist. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 2 mi of the line.
Metavolcanic. Age: Neoproterozoic, 542 to 1,000 million years old. About 1 mi of the line.
Metagranite, metadiorite. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 4 smaller units along the line are not listed.

A raindrop that lands in Ben Avon reaches the Atlantic Ocean by way of Lawsons Fork Creek, the Pacolet, the Broad, the Congaree, the Santee and the South Santee: about 290 river miles.
Lake on the way: Lib Pines Lake.
75 miles of the trip are on the Broad.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Ben Avon; river miles along the main stem, rounded.
Ben Avon has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 31° in January. About 50 inches of rain fall in a normal year.
On November 14 Ben Avon normally reaches 64° and falls to 38°. The record high is 79°, in 2007; the record low 19°, in 2013. The most rain on this date, 1.33 in, fell in 2024.
