72° on Nov. 11, 2022, the hottest reading for this week of the year since 1948. Next is 71° in 1989.
Adeline’s center stands about 810 ft above sea level. Within three miles the land runs from 720 ft to 940 ft, a difference of 220 ft: rolling country. The highest named summit within 15 miles is Coffman Bluff, about 960 ft, 3 miles north-northwest.
Under the town center the state geologic map shows Platteville Group (dolostone, limestone), from the Late Ordovician, 454 to 459 million years old.
The section below crosses 5 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 11 mi of the line.
Shale, limestone. Age: Late Ordovician, 445 to 454 million years old. About 6 mi of the line.
Dolostone, limestone. Age: Late Ordovician, 454 to 459 million years old. About 4 mi of the line.
Sandstone, limestone, dolostone. Age: Middle Ordovician to Late Ordovician, 454 to 468 million years old. About 1 mi of the line.
Dolostone, limestone. Age: Silurian, 422 to 445 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.

A raindrop that lands in Adeline reaches the Gulf of America by way of the Leaf, the Rock River and the Mississippi: about 1,580 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Adeline; river miles along the main stem, rounded.
Adeline has a hot-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 11° in January. A normal year brings about 34 inches of snow; with the rain, that comes to about 38 inches of water.
On November 14 Adeline normally reaches 47° and falls to 29°. The record high is 71°, in 1989; the record low 10°, in 1996. The most rain on this date, 2.50 in, fell in 1951.
Normals 1991–2020 and records since 1948 at Freeport Wastewater Plant, 12 miles north-northwest. NOAA, through RCC-ACIS.
