72° on Nov. 14, 1999, the hottest reading for this week of the year since 1952. Next is 72° in 2012.
York’s center stands about 1,300 ft above sea level. Within three miles the land runs from 1,250 ft to 1,350 ft, a difference of 100 ft: gently rolling country.
Under the town center the state geologic map shows Middle Devonian (dolostone, limestone, shale), from the Middle Devonian, 384 to 394 million years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 51×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone, dolostone. Age: Late Ordovician, 445 to 459 million years old. About 9 mi of the line.
Dolostone, limestone, shale. Age: Middle Devonian, 384 to 394 million years old. About 5 mi of the line.
Limestone, dolostone. Age: Middle Devonian to Late Devonian, 374 to 388 million years old. About 3 mi of the line.
Shale, dolostone. Age: Late Ordovician, 447 to 454 million years old. About 3 mi of the line.
Dolostone, limestone. Age: Middle Devonian, 384 to 394 million years old. About 3 mi of the line.
Dolostone, sandstone. Age: Early Ordovician, 471 to 487 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. 1 smaller unit along the line are not listed.
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 York reaches the Gulf of America by way of Canfield Creek, the South Branch Root, the Root and the Mississippi: about 1,770 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of York; river miles along the main stem, rounded.
York has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 4° in January. A normal year brings about 42 inches of snow; with the rain, that comes to about 37 inches of water.
On November 14 York normally reaches 43° and falls to 24°. The record high is 72°, in 1999; the record low −4°, in 1959. The most rain on this date, 0.30 in, fell in 2010.
Normals 1991–2020 and records since 1952 at Preston, 14 miles northeast, 370 ft lower. NOAA, through RCC-ACIS.
