York’s center stands about 1,040 ft above sea level. Within three miles the land runs from 860 ft to 1,150 ft, a difference of 290 ft: rolling country.
Under the town center the state geologic map shows Sinnipee Group (dolostone), from the Ordovician, 445 to 487 million years old.
The section below crosses 2 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.
Sandstone. Age: Ordovician, 445 to 487 million years old. About 12 mi of the line.
Dolostone. Age: Ordovician, 445 to 487 million years old. About 12 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in York reaches the Gulf of America by way of Sawmill Creek, the East Branch Pecatonica, the Pecatonica, the Rock River and the Mississippi: about 1,750 river miles.
1,450 miles of the trip are on the Mississippi.
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 hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 11° in January. A normal year brings about 42 inches of snow; with the rain, that comes to about 40 inches of water.
Normals 1991–2020 and records since 1940 at Monroe Wwtp, 16 miles south-southeast. NOAA, through RCC-ACIS.
