71° on Nov. 14, 1999, the hottest reading for this week of the year since 1892. Next is 69° in 1917.
Eitzen’s center stands about 1,160 ft above sea level. Within three miles the land runs from 820 ft to 1,160 ft, a difference of 340 ft: rolling country.
Under the town center the state geologic map shows Lower Ordovician (dolostone, sandstone), from the Early Ordovician, 471 to 487 million years old.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 27×. 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, sandstone. Age: Early Ordovician, 471 to 487 million years old. About 7 mi of the line.
Dolostone, sandstone. Age: Early Ordovician to Late Ordovician, 454 to 487 million years old. About 6 mi of the line.
Shale, limestone, sandstone. Age: Middle Ordovician to Late Ordovician, 445 to 471 million years old. About 5 mi of the line.
Sandstone, dolostone. Age: Cambrian, 487 to 497 million years old. About 2 mi of the line.
Limestone, dolostone. Age: Late Ordovician, 445 to 459 million years old. About 2 mi of the line.
Sandstone, shale. Age: Middle Cambrian, 497 to 521 million 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. 2 smaller units along the line are not listed.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Eitzen reaches the Gulf of America by way of Winnebago Creek, Minnesota Slough and the Mississippi: about 1,670 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Eitzen; river miles along the main stem, rounded.
Eitzen has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 8° in January. A normal year brings about 45 inches of snow; with the rain, that comes to about 38 inches of water.
On November 14 Eitzen normally reaches 43° and falls to 27°. The record high is 71°, in 1999; the record low −3°, in 1986. The most rain on this date, 1.40 in, fell in 1902.
Normals 1991–2020 and records since 1892 at Caledonia, 9 miles north-northwest. NOAA, through RCC-ACIS.
