71° on Nov. 14, 1990, the hottest reading for this week of the year since 1936. Next is 68° in 1939.
Minneiska’s center stands about 660 ft above sea level. Within three miles the land runs from 650 ft to 1,140 ft, a difference of 490 ft: hilly country. The highest named summit within 15 miles is Greenfield Hill, about 1,240 ft, 9 miles north-northwest.
Under the town center the state geologic map shows Middle and Upper Cambrian (sandstone, siltstone, shale), from the Middle Cambrian to Cambrian, 487 to 521 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 31×. 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. Age: Cambrian, 487 to 542 million years old. About 8 mi of the line.
Dolostone, sandstone. Age: Early Ordovician, 471 to 487 million years old. About 5 mi of the line.
Sandstone, siltstone, shale. Age: Middle Cambrian to Cambrian, 487 to 521 million years old. About 5 mi of the line.
Sandstone, siltstone, shale. Age: Cambrian, 487 to 497 million years old. About 4 mi of the line.
Dolostone. Age: Early Ordovician, 471 to 487 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.
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 Minneiska reaches the Gulf of America by way of the Mississippi: about 1,720 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Minneiska; river miles along the main stem, rounded.
Minneiska has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 8° in January. A normal year brings about 37 inches of snow; with the rain, that comes to about 37 inches of water.
On November 14 Minneiska normally reaches 43° and falls to 28°. The record high is 71°, in 1990; the record low 2°, in 1940. The most rain on this date, 0.60 in, fell in 1951.
Normals 1991–2020 and records since 1936 at Alma Dam 4, 6 miles north. NOAA, through RCC-ACIS.
