Glenwood’s center stands about 1,160 ft above sea level. Within three miles the land runs from 1,130 ft to 1,420 ft, a difference of 290 ft: rolling country. The highest named summit within 15 miles is Blue Mounds, about 1,340 ft, 10 miles southwest.
Under the town center the state geologic map shows Foliated to gneissic tonalite and granodiorite (orthogneiss), from the Paleoarchean to Mesoarchean, 2.8 to 3.6 billion years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 60×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Orthogneiss. Age: Paleoarchean to Mesoarchean, 2.8 to 3.6 billion years old. About 12 mi of the line.
Orthogneiss, migmatite. Age: Paleoarchean to Mesoarchean, 2.8 to 3.6 billion years old. About 7 mi of the line.
Schist, paragneiss. Age: Neoarchean, 2.5 to 2.8 billion years old. About 3 mi of the line.
Orthogneiss. Age: Paleoarchean to Mesoarchean, 2.8 to 3.6 billion years old. About 2 mi of the line.
Age: Paleoproterozoic, 1.8 to 2 billion years old. About 0.5 mi of the line.

A raindrop that lands in Glenwood reaches the Gulf of America by way of the East Branch Chippewa, the Chippewa, the Minnesota and the Mississippi: about 2,200 river miles.
Lake on the way: Lake Pepin.
1,750 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Glenwood; river miles along the main stem, rounded.
Glenwood has a dry-winter warm-summer continental climate. Summer afternoons average 80° in July; winter nights fall to about 2° in January. About 24 inches of rain fall in a normal year.
On November 14 Glenwood normally reaches 38° and falls to 24°. The record high is 69°, in 1953; the record low −8°, in 1959. The most rain on this date, 0.22 in, fell in 1951.
Normals 1991–2020 and records since 1940 at Alexandria Chandler Field, 15 miles north, 260 ft higher. NOAA, through RCC-ACIS.
