3.42 inches of rain fell in two days, the most for this week of the year since records began in 1900. The next wettest, 2.98 inches, fell in 1928.
Joy’s center stands about 690 ft above sea level. Within three miles the land runs from 580 ft to 700 ft, a difference of 120 ft: gently rolling country.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. 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, sandstone. Age: Early Pennsylvanian to Middle Pennsylvanian, 307 to 324 million years old. About 12 mi of the line.
Limestone, dolostone. Age: Middle Devonian to Late Devonian, 374 to 388 million years old. About 4 mi of the line.
Shale. Age: Middle Devonian to Late Devonian, 359 to 388 million years old. About 4 mi of the line.
Limestone. Age: Middle Devonian, 384 to 394 million years old. About 3 mi of the line.
Shale, siltstone. Age: Late Devonian, 359 to 374 million years old. About 1 mi of the line.

A raindrop that lands in Joy reaches the Gulf of America by way of the Mad, Pope Creek and the Mississippi: about 1,410 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Joy; river miles along the main stem, rounded.
Joy has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 13° in January. A normal year brings about 22 inches of snow; with the rain, that comes to about 39 inches of water.
On November 14 Joy normally reaches 50° and falls to 30°. The record high is 74°, in 1971; the record low 6°, in 1940. The most rain on this date, 1.24 in, fell in 1926.
Normals 1991–2020 and records since 1900 at Aledo, 7 miles east. NOAA, through RCC-ACIS.
