4.45 inches of rain fell in two days, the most for this week of the year since records began in 1980. The next wettest, 2.62 inches, fell in 2015.
Slickville’s center stands about 1,180 ft above sea level. Within three miles the land runs from 890 ft to 1,380 ft, a difference of 490 ft: hilly country.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 32×. 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: Carboniferous, 299 to 324 million years old. About 11 mi of the line.
Shale, clastic. Age: Carboniferous, 299 to 324 million years old. About 9 mi of the line.
Limestone, shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 5 mi of the line.

A raindrop that lands in Slickville reaches the Gulf of America by way of Loyalhanna Creek, the Kiskiminetas, the Allegheny, the Ohio and the Mississippi: about 2,010 river miles.
970 miles of the trip are on the Ohio.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Slickville; river miles along the main stem, rounded.
Slickville has a warm-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 19° in January. About 43 inches of rain fall in a normal year.
On November 14 Slickville normally reaches 52° and falls to 30°. The record high is 74°, in 1994; the record low 12°, in 2019. The most rain on this date, 1.13 in, fell in 1995.
Normals 1991–2020 and records since 1980 at Loyalhanna Lake, 4 miles east, 190 ft lower. NOAA, through RCC-ACIS.
