70° on Nov. 11, 2022, the hottest reading for this week of the year since 1940. Next is 68° in 2025.
Orangeville’s center stands about 820 ft above sea level. Within three miles the land runs from 780 ft to 1,000 ft, a difference of 220 ft: rolling country.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 56×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Dolostone, limestone. Age: Late Ordovician, 447 to 459 million years old. About 10 mi of the line.
Dolostone. Age: Ordovician, 445 to 487 million years old. About 9 mi of the line.
Dolostone, limestone. Age: Late Ordovician, 454 to 459 million years old. About 3 mi of the line.
Sandstone, limestone, dolostone. Age: Middle Ordovician to Late Ordovician, 454 to 468 million years old. About 2 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 Orangeville reaches the Gulf of America by way of Richland Creek, the Pecatonica, the Rock River and the Mississippi: about 1,700 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Orangeville; river miles along the main stem, rounded.
Orangeville 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.
