77° on Nov. 11, 2020, the hottest reading for this week of the year since 1921. Next is 72° in 2012.
Limestone’s center stands about 1,550 ft above sea level. Within three miles the land runs from 1,110 ft to 1,880 ft, a difference of 770 ft: hilly country. The highest named summit within 15 miles is Bull Hill, about 2,030 ft, 14 miles east.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 20×. 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, siltstone. Age: Carboniferous, 324 to 359 million years old. About 10 mi of the line.
Sandstone, conglomerate. Age: Carboniferous, 299 to 324 million years old. About 9 mi of the line.
Sandstone, shale. Age: Late Devonian, 359 to 384 million years old. About 2 mi of the line.
Siltstone, conglomerate. Age: Late Devonian, 359 to 384 million years old. About 0.9 mi of the line.
Sandstone. Age: Carboniferous, 324 to 359 million years old. About 0.9 mi of the line.
Siltstone, shale. Age: Carboniferous, 324 to 359 million years old. About 0.9 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Limestone reaches the Gulf of America by way of East Hickory Creek, the Allegheny, the Ohio and the Mississippi: about 2,120 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 Limestone; river miles along the main stem, rounded.
Limestone has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 19° in January. A normal year brings about 51 inches of snow; with the rain, that comes to about 47 inches of water.
On November 14 Limestone normally reaches 51° and falls to 33°. The record high is 71°, in 1989; the record low 12°, in 1986. The most rain on this date, 0.86 in, fell in 1997.
Normals 1991–2020 and records since 1921 at Tionesta 2 SE Lake, 15 miles south-southwest, 350 ft lower. NOAA, through RCC-ACIS.
