Apple River’s center stands about 1,000 ft above sea level. Within three miles the land runs from 900 ft to 1,090 ft, a difference of 190 ft: gently rolling country. The highest named summit within 15 miles is White Hill, about 1,270 ft, 7 miles west-northwest.
Under the town center the state geologic map shows Maquoketa Formation or Group (shale, limestone), from the Late Ordovician, 445 to 454 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 47×. 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 9 mi of the line.
Dolostone. Age: Ordovician, 445 to 487 million years old. About 8 mi of the line.
Shale, limestone. Age: Late Ordovician, 445 to 454 million years old. About 3 mi of the line.
Shale, dolostone. Age: Ordovician, 445 to 487 million years old. About 3 mi of the line.
Sandstone. Age: Ordovician, 445 to 487 million years old. About 0.6 mi of the line.

A raindrop that lands in Apple River reaches the Gulf of America by way of Kentucky Creek, the Apple and the Mississippi: about 1,570 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Apple River; river miles along the main stem, rounded.
Apple River has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 12° in January. A normal year brings about 36 inches of snow; with the rain, that comes to about 39 inches of water.
On November 14 Apple River normally reaches 46° and falls to 30°. The record high is 70°, in 1989; the record low 7°, in 1986. The most rain on this date, 0.77 in, fell in 1980.
Normals 1991–2020 and records since 1943 at Stockton 3 NNE, 9 miles southeast. NOAA, through RCC-ACIS.
