5.81 inches of rain fell in two days, the most for this week of the year since records began in 1871. The next wettest, 5.63 inches, fell in 2011.
Maynard’s center stands about 430 ft above sea level. Within three miles the land runs from 300 ft to 520 ft, a difference of 220 ft: rolling country. The highest named summit within 15 miles is Bellah Hills, about 760 ft, 12 miles west-northwest.
Under the town center the state geologic map shows Cotter and Jefferson City Dolomites (dolostone), from the Early Ordovician, 471 to 487 million years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 49×. 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 13 mi of the line.
Coarse-detrital, fine-detrital. Age: Holocene, less than 12,000 years old. About 3 mi of the line.
Coarse-detrital, fine-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 2 mi of the line.
Sandstone, mudstone. Age: Cretaceous, 66 to 145 million years old. About 2 mi of the line.
Sand. Age: Pleistocene, less than 2.6 million years old. About 2 mi of the line.
Coarse-detrital, fine-detrital. Age: Pleistocene, less than 2.6 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. 1 smaller unit along the line are not listed.

A raindrop that lands in Maynard reaches the Gulf of America by way of Lemmons Creek, the Fourche, the Black River, the White River and the Mississippi: about 990 river miles.
620 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Maynard; river miles along the main stem, rounded.
Maynard has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 26° in January. A normal year brings about 6 inches of snow; with the rain, that comes to about 52 inches of water.
On November 14 Maynard normally reaches 59° and falls to 37°. The record high is 80°, in 1931; the record low 12°, in 2019. The most rain on this date, 3.81 in, fell in 1957.
Normals 1991–2020 and records since 1871 at Pocahontas 1, 11 miles south-southwest, 120 ft lower. NOAA, through RCC-ACIS.
