The Little York plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
78° on Nov. 11, 2022, the hottest reading for this week of the year since 1995. Next is 76° in 1999.
Little York’s center stands about 620 ft above sea level. Within three miles the land runs from 570 ft to 720 ft, a difference of 150 ft: gently rolling country.
Under the town center the state geologic map shows Meppen Limestone, Fern Glen Formation, and Burlington-Keokuk Limestone, from the Early Mississippian to Middle Mississippian, 331 to 359 million years old.
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 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

A raindrop that lands in Little York reaches the Gulf of America by way of Cedar Creek, Henderson Creek and the Mississippi: about 1,410 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Little York; river miles along the main stem, rounded.
Little York has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 14° in January. About 39 inches of rain fall in a normal year.
On November 14 Little York normally reaches 50° and falls to 30°. The record high is 76°, in 1999; the record low 11°, in 2014. The most rain on this date, 0.27 in, fell in 2008.
