77° on Nov. 11, 2020, the hottest reading for this week of the year since 1946. Next is 75° in 1993.
Ohiopyle’s center stands about 1,230 ft above sea level. Within three miles the land runs from 1,160 ft to 2,330 ft, a difference of 1,170 ft: steep hill country. The highest named summit within 15 miles is Rich Hill, about 2,850 ft, 15 miles southeast.
Under the town center the state geologic map shows Allegheny Formation (sandstone), from the Carboniferous, 299 to 324 million years old.
The section below crosses 12 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 10×. 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 7 mi of the line.
Shale. Age: Carboniferous, 299 to 324 million years old. About 5 mi of the line.
Shale, clastic. Age: Carboniferous, 299 to 324 million years old. About 5 mi of the line.
Sandstone, conglomerate. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.
Sandstone. Age: Carboniferous, 324 to 359 million years old. About 1 mi of the line.
Shale, siltstone, sandstone. Age: Carboniferous, 324 to 359 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. 6 smaller units along the line are not listed.

A raindrop that lands in Ohiopyle reaches the Gulf of America by way of the Youghiogheny, the Monongahela, the Ohio and the Mississippi: about 2,020 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 Ohiopyle; river miles along the main stem, rounded.
Ohiopyle has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 19° in January. A normal year brings about 61 inches of snow; with the rain, that comes to about 47 inches of water.
On November 14 Ohiopyle normally reaches 52° and falls to 30°. The record high is 74°, in 1989; the record low 7°, in 1986. The most rain on this date, 0.90 in, fell in 1972.
Normals 1991–2020 and records since 1946 at Confluence 1 SW Dam, 8 miles southeast, 260 ft higher. NOAA, through RCC-ACIS.
