Yorkshire’s center stands about 1,890 ft above sea level. Within three miles the land runs from 1,270 ft to 2,110 ft, a difference of 840 ft: hilly country. The highest named summit within 15 miles is Poverty Hill, about 2,370 ft, 15 miles southwest.
Under the town center the state geologic map shows Machias Formation (shale, siltstone, sandstone), from the Late Devonian, 359 to 384 million years old.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 18×. 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, siltstone, sandstone. Age: Late Devonian, 359 to 384 million years old. About 24 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 Yorkshire reaches Lake Erie by way of the Lime Lake Outlet, Elton Creek and Cattaraugus Creek: about 55 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Yorkshire; river miles along the main stem, rounded.
Yorkshire has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 13° in January. A normal year brings about 109 inches of snow; with the rain, that comes to about 45 inches of water.
On November 14 Yorkshire normally reaches 47° and falls to 29°. The record high is 66°, in 1989; the record low −4°, in 1905. The most rain on this date, 1.04 in, fell in 1972.
Normals 1991–2020 and records since 1896 at Franklinville, 11 miles south-southeast, 300 ft lower. NOAA, through RCC-ACIS.
