North Washington’s center stands about 1,140 ft above sea level. Within three miles the land runs from 1,090 ft to 1,200 ft, a difference of 110 ft: gently rolling country.
Under the town center the state geologic map shows Cedar Valley Group (limestone, dolostone), from the Middle Devonian to Late Devonian, 374 to 388 million years old.
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 60×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone, dolostone. Age: Middle Devonian to Late Devonian, 374 to 388 million years old. About 21 mi of the line.
Dolostone, limestone. Age: Middle Devonian, 384 to 394 million years old. About 4 mi of the line.

A raindrop that lands in North Washington reaches the Gulf of America by way of the Little Wapsipinicon, the Wapsipinicon and the Mississippi: about 1,710 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of North Washington; river miles along the main stem, rounded.
North Washington has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 6° in January. A normal year brings about 38 inches of snow; with the rain, that comes to about 41 inches of water.
On November 14 North Washington normally reaches 44° and falls to 24°. The record high is 70°, in 1990; the record low −8°, in 1959. The most rain on this date, 1.18 in, fell in 1902.
