The Eden plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
69° on Nov. 17, 2016, the hottest reading for this week of the year since 1996. Next is 68° in 2023.
Eden’s center stands about 1,020 ft above sea level. Within three miles the land runs from 890 ft to 1,180 ft, a difference of 290 ft: rolling country. The highest named summit within 15 miles is Dundee Mountain, about 1,250 ft, 10 miles east-southeast.
Under the town center the state geologic map shows Maquoketa Formation (shale, dolostone), from the Ordovician, 445 to 487 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 46×. 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. Age: Silurian, 422 to 445 million years old. About 12 mi of the line.
Shale, dolostone. Age: Ordovician, 445 to 487 million years old. About 4 mi of the line.
Dolostone. Age: Ordovician, 445 to 487 million years old. About 4 mi of the line.

A raindrop that lands in Eden reaches Lake Michigan by way of De Neveu Creek and the Fox River: about 80 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Lake on the way: Lake Winnebago 6124.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Eden; river miles along the main stem, rounded.
Eden has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 11° in January. About 28 inches of rain fall in a normal year.
On November 14 Eden normally reaches 45° and falls to 29°. The record high is 64°, in 2025; the record low 10°, in 1996. The most rain on this date, 0.10 in, fell in 2024.
