Lost Nation’s center stands about 760 ft above sea level. Within three miles the land runs from 650 ft to 850 ft, a difference of 200 ft: gently rolling country.
Under the town center the state geologic map shows Ancell Group (sandstone, limestone, dolostone), from the Middle Ordovician to Late Ordovician, 454 to 468 million years old.
The section below crosses 4 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.
Sandstone, limestone, dolostone. Age: Middle Ordovician to Late Ordovician, 454 to 468 million years old. About 13 mi of the line.
Dolostone, limestone. Age: Late Ordovician, 454 to 459 million years old. About 6 mi of the line.
Dolostone, limestone. Age: Late Ordovician, 447 to 459 million years old. About 4 mi of the line.
Dolostone. Age: Early Ordovician to Middle Ordovician, 459 to 487 million years old. About 2 mi of the line.

A raindrop that lands in Lost Nation reaches the Gulf of America by way of Clear Creek, the Rock River and the Mississippi: about 1,560 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lost Nation; river miles along the main stem, rounded.
Lost Nation has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 14° in January. A normal year brings about 31 inches of snow; with the rain, that comes to about 40 inches of water.
On November 14 Lost Nation normally reaches 48° and falls to 31°. The record high is 75°, in 1971; the record low 5°, in 1986. The most rain on this date, 1.60 in, fell in 1926.
Normals 1991–2020 and records since 1893 at Dixon Wwtp, 9 miles southwest, 110 ft lower. NOAA, through RCC-ACIS.
