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.
72° on Nov. 14, 1953, the hottest reading for this week of the year since 1893. Next is 72° in 2001.
Eden’s center stands about 1,840 ft above sea level. Within three miles the land runs from 1,780 ft to 1,890 ft, a difference of 110 ft: gently rolling country. The highest named summit within 15 miles is Pleasant Peak, about 2,060 ft, 14 miles north.
Under the town center the state geologic map shows Pierre Shale (shale, bentonite), from the Late Cretaceous, 66 to 100 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 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.
Shale, bentonite. Age: Late Cretaceous, 66 to 100 million years old. About 23 mi of the line.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 1 mi of the line.
Chalk, marlstone, shale. Age: Late Cretaceous, 66 to 100 million years old. About 0.4 mi of the line.

Eden has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 0° in January. A normal year brings about 45 inches of snow; with the rain, that comes to about 24 inches of water.
On November 14 Eden normally reaches 40° and falls to 20°. The record high is 72°, in 1953; the record low −13°, in 1940. The most rain on this date, 0.53 in, fell in 1928.
