74° on Nov. 11, 2020, the hottest reading for this week of the year since 1964. Next is 70° in 1964.
Wopsononock’s center stands about 2,510 ft above sea level. Within three miles the land runs from 1,290 ft to 2,570 ft, a difference of 1,280 ft: steep hill country.
The section below crosses 16 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 12×. 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 5 mi of the line.
Shale. Age: Carboniferous, 299 to 324 million years old. About 4 mi of the line.
Limestone. Age: Silurian to Devonian, 359 to 445 million years old. About 2 mi of the line.
Shale, sandstone. Age: Silurian, 422 to 445 million years old. About 2 mi of the line.
Siltstone, mudstone. Age: Late Devonian, 359 to 384 million years old. About 2 mi of the line.
Sandstone, conglomerate. Age: Carboniferous, 299 to 324 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. 10 smaller units along the line are not listed.

A raindrop that lands in Wopsononock reaches Chesapeake Bay and the Atlantic Ocean by way of the Little Juniata, the Juniata and the Susquehanna: about 230 river miles.
Lake on the way: Lake Aldred.
100 miles of the trip are on the Juniata.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Wopsononock; river miles along the main stem, rounded.
Wopsononock has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 16° in January. A normal year brings about 80 inches of snow; with the rain, that comes to about 49 inches of water.
On November 14 Wopsononock normally reaches 48° and falls to 29°. The record high is 69°, in 1994; the record low 5°, in 1986. The most rain on this date, 0.74 in, fell in 1993.
