78° on Nov. 11, 2012, the hottest reading for this week of the year since 1893. Next is 74° in 1931.
Ladora’s center stands about 790 ft above sea level. Within three miles the land runs from 760 ft to 930 ft, a difference of 170 ft: gently rolling country.
Under the town center the state geologic map shows Lime Creek Formation (shale, limestone, dolostone), from the Late Devonian, 374 to 384 million 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 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.
Shale, limestone, dolostone. Age: Late Devonian, 374 to 384 million years old. About 10 mi of the line.
Shale, siltstone. Age: Late Devonian, 359 to 374 million years old. About 5 mi of the line.
Limestone, dolostone. Age: Middle Devonian to Late Devonian, 374 to 388 million years old. About 5 mi of the line.
Shale, sandstone, siltstone. Age: Early Pennsylvanian to Middle Pennsylvanian, 307 to 324 million years old. About 3 mi of the line.
Dolostone, limestone, siltstone. Age: Early Mississippian, 347 to 359 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Ladora reaches the Gulf of America by way of the Iowa and the Mississippi: about 1,550 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Ladora; river miles along the main stem, rounded.
Ladora has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 10° in January. A normal year brings about 28 inches of snow; with the rain, that comes to about 36 inches of water.
On November 14 Ladora normally reaches 48° and falls to 28°. The record high is 73°, in 1999; the record low −2°, in 1916. The most rain on this date, 1.80 in, fell in 1899.
Normals 1991–2020 and records since 1893 at Belle Plaine, 10 miles north-northwest. NOAA, through RCC-ACIS.
