78° on Nov. 14, 1971, the hottest reading for this week of the year since 1871. Next is 74° in 1911.
Park Ridge’s center stands about 650 ft above sea level. Within three miles the land runs from 620 ft to 690 ft, a difference of 70 ft: gently rolling country.
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 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.
Dolostone, limestone. Age: Silurian, 422 to 445 million years old. About 18 mi of the line.
Sedimentary. Age: Cambrian to Carboniferous, 299 to 542 million years old. About 3 mi of the line.

A raindrop that lands in Park Ridge reaches the Gulf of America by way of the Des Plaines, the Illinois and the Mississippi: about 1,530 river miles.
Lake on the way: Peoria Lake.
1,190 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Park Ridge; river miles along the main stem, rounded.
Park Ridge has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 19° in January. A normal year brings about 38 inches of snow; with the rain, that comes to about 38 inches of water.
On November 14 Park Ridge normally reaches 49° and falls to 35°. The record high is 78°, in 1971; the record low 14°, in 1916. The most rain on this date, 1.19 in, fell in 1926.
