3.10 inches of rain fell in two days, the most for this week of the year since records began in 1936. The next wettest, 1.98 inches, fell in 2021.
Ettrick’s center stands about 790 ft above sea level. Within three miles the land runs from 750 ft to 1,150 ft, a difference of 400 ft: rolling country. The highest named summit within 15 miles is Square Bluff, about 1,300 ft, 11 miles north-northwest.
Under the town center the state geologic map shows Cambrian, undivided (sandstone), from the Cambrian, 487 to 542 million years old.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 30×. 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. Age: Cambrian, 487 to 542 million years old. About 24 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 Ettrick reaches the Gulf of America by way of South Fork Beaver Creek, Beaver Creek, the Black River, the Dodge Chute and the Mississippi: about 1,710 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Ettrick; river miles along the main stem, rounded.
Ettrick has a hot-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 9° in January. A normal year brings about 36 inches of snow; with the rain, that comes to about 35 inches of water.
On November 14 Ettrick normally reaches 44° and falls to 29°. The record high is 65°, in 1964; the record low 7°, in 1996. The most rain on this date, 0.46 in, fell in 2010.
Normals 1991–2020 and records since 1936 at Trempealeau Dam 6, 15 miles southwest, 130 ft lower. NOAA, through RCC-ACIS.
