Cyrus’s center stands about 1,150 ft above sea level. Within three miles the land runs from 1,110 ft to 1,230 ft, a difference of 120 ft: gently rolling country. The highest named summit within 15 miles is Lookout Mountain, about 1,530 ft, 15 miles north-northeast.
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.
Orthogneiss, migmatite. Age: Paleoarchean to Mesoarchean, 2.8 to 3.6 billion years old. About 12 mi of the line.
Orthogneiss. Age: Paleoarchean to Mesoarchean, 2.8 to 3.6 billion years old. About 9 mi of the line.
Granitic. Age: Neoarchean, 2.5 to 2.8 billion years old. About 3 mi of the line.

A raindrop that lands in Cyrus reaches the Gulf of America by way of the Chippewa, the Minnesota and the Mississippi: about 2,180 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 Cyrus; river miles along the main stem, rounded.
Cyrus has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 1° in January. A normal year brings about 45 inches of snow; with the rain, that comes to about 27 inches of water.
On November 14 Cyrus normally reaches 40° and falls to 22°. The record high is 69°, in 1999; the record low −10°, in 1932. The most rain on this date, 0.80 in, fell in 1909.
Normals 1991–2020 and records since 1885 at Morris West Central Research And Outreach Center, 7 miles west-southwest. NOAA, through RCC-ACIS.
