3.76 inches of rain fell in two days, the most for this week of the year since records began in 1892. The next wettest, 1.80 inches, fell in 1971.
Wyanett’s center stands about 970 ft above sea level. Within three miles the land runs from 920 ft to 1,020 ft, a difference of 100 ft: gently rolling country.
Under the town center the state geologic map shows Middle and Upper Cambrian (sandstone, siltstone, shale), from the Middle Cambrian to Cambrian, 487 to 521 million years old.
The section below crosses 7 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.
Sandstone, siltstone, shale. Age: Middle Cambrian to Cambrian, 487 to 521 million years old. About 11 mi of the line.
Sandstone, siltstone. Age: Mesoproterozoic, 1 to 1.2 billion years old. About 5 mi of the line.
Sandstone, siltstone, shale. Age: Cambrian, 487 to 497 million years old. About 2 mi of the line.
Mylonite, gneiss, schist. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 2 mi of the line.
Gabbro, pyroxenite, diorite. Age: Paleoproterozoic, 1.6 to 1.8 billion years old. About 1 mi of the line.
Granodiorite, granite. Age: Paleoproterozoic, 1.6 to 1.8 billion 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. 1 smaller unit along the line are not listed.

A raindrop that lands in Wyanett reaches the Gulf of America by way of North Brook, Green Lake Brook, the Rum and the Mississippi: about 1,920 river miles.
Lake on the way: Lake Pepin.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Wyanett; river miles along the main stem, rounded.
Wyanett has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 4° in January. A normal year brings about 44 inches of snow; with the rain, that comes to about 30 inches of water.
On November 14 Wyanett normally reaches 42° and falls to 26°. The record high is 69°, in 1999; the record low −3°, in 1959. The most rain on this date, 0.72 in, fell in 1988.
