Wisconsin Dells’s center stands about 920 ft above sea level. Within three miles the land runs from 810 ft to 1,040 ft, a difference of 230 ft: rolling country. The highest named summit within 15 miles is Sauk Point, about 1,630 ft, 15 miles south-southeast.
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 38×. 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.

A raindrop that lands in Wisconsin Dells reaches the Gulf of America by way of the Wisconsin and the Mississippi: about 1,750 river miles.
Lake on the way: Lake Wisconsin.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Wisconsin Dells; river miles along the main stem, rounded.
Wisconsin Dells has a warm-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 10° in January. A normal year brings about 43 inches of snow; with the rain, that comes to about 39 inches of water.
On November 14 Wisconsin Dells normally reaches 46° and falls to 28°. The record high is 72°, in 1999; the record low −3°, in 1959. The most rain on this date, 1.16 in, fell in 1956.
