−2° on Nov. 17, 1959, the coldest reading for this week of the year since 1900. Next is 2° in 1940.
Grandview’s center stands about 710 ft above sea level. Within three miles the land runs from 530 ft to 720 ft, a difference of 190 ft: gently rolling country.
The section below crosses 6 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.
Limestone, dolostone. Age: Middle Devonian to Late Devonian, 374 to 388 million years old. About 11 mi of the line.
Shale, siltstone. Age: Late Devonian, 359 to 374 million years old. About 9 mi of the line.
Shale, limestone, dolostone. Age: Late Devonian, 374 to 384 million years old. About 2 mi of the line.
Dolostone, limestone. Age: Early Mississippian to Middle Mississippian, 331 to 359 million years old. About 0.9 mi of the line.
Dolostone, limestone. Age: Middle Devonian, 384 to 394 million years old. About 0.7 mi of the line.
Dolostone. Age: Silurian, 431 to 440 million years old. About 0.4 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 Grandview reaches the Gulf of America by way of Turkey Run, the Iowa and the Mississippi: about 1,430 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Grandview; river miles along the main stem, rounded.
Grandview has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 11° in January. A normal year brings about 31 inches of snow; with the rain, that comes to about 39 inches of water.
On November 14 Grandview normally reaches 49° and falls to 27°. The record high is 76°, in 1958; the record low 0°, in 1959. The most rain on this date, 0.94 in, fell in 1926.
Normals 1991–2020 and records since 1900 at Columbus Junction, 9 miles west, 120 ft lower. NOAA, through RCC-ACIS.
