Wells’s center stands about 1,150 ft above sea level. Within three miles the land runs from 1,090 ft to 1,180 ft, a difference of 90 ft: gently rolling country.
Under the town center the state geologic map shows Upper Ordovician (limestone, dolostone), from the Late Ordovician, 445 to 459 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 63×. 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, limestone, sandstone. Age: Middle Ordovician to Late Ordovician, 445 to 471 million years old. About 10 mi of the line.
Limestone, dolostone. Age: Late Ordovician, 445 to 459 million years old. About 10 mi of the line.
Dolostone, limestone, shale. Age: Middle Devonian, 384 to 394 million years old. About 4 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
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 Wells reaches the Gulf of America by way of the Maple, the Le Sueur, the Blue Earth, the Minnesota and the Mississippi: about 2,010 river miles.
Lake on the way: Lake Pepin.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Wells; river miles along the main stem, rounded.
Wells has a hot-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 5° in January. A normal year brings about 40 inches of snow; with the rain, that comes to about 34 inches of water.
On November 14 Wells normally reaches 44° and falls to 25°. The record high is 76°, in 1999; the record low 2°, in 2014. The most rain on this date, 0.49 in, fell in 1991.
