3.59 inches of rain fell in two days, the most for this week of the year since records began in 1960. The next wettest, 2.87 inches, fell in 2011.
Allenville’s center stands about 350 ft above sea level. Within three miles the land runs from 330 ft to 510 ft, a difference of 180 ft: gently rolling country. The highest named summit within 15 miles is Turkey Hill, about 760 ft, 14 miles west-northwest.
Under the town center the state geologic map shows Holocene series (clay, silt, sand), from the Holocene, less than 12,000 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 58×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 10 mi of the line.
Clay, silt, sand. Age: Holocene, less than 12,000 years old. About 9 mi of the line.
Dolostone, sandstone, limestone. Age: Early Ordovician to Middle Ordovician, 459 to 487 million years old. About 3 mi of the line.
Clay, sand. Age: Late Cretaceous, 66 to 100 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 Allenville reaches the Gulf of America by way of the Castor River Diversion Channel and the Mississippi: about 1,040 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Allenville; river miles along the main stem, rounded.
Allenville has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 26° in January. About 48 inches of rain fall in a normal year.
On November 14 Allenville normally reaches 57° and falls to 37°. The record high is 80°, in 1964; the record low 13°, in 1986. The most rain on this date, 1.34 in, fell in 2011.
Normals 1991–2020 and records since 1960 at Cape Girardeau Faa Airport, 10 miles east. NOAA, through RCC-ACIS.
