80° on Nov. 11, 1989, the hottest reading for this week of the year since 1940. Next is 80° in 2003.
Doyle’s center stands about 950 ft above sea level. Within three miles the land runs from 840 ft to 1,350 ft, a difference of 510 ft: hilly country. The highest named summit within 15 miles is Chestnut Mountain, about 2,050 ft, 12 miles east.
Under the town center the state geologic map shows St. Louis Limestone and Warsaw Limestone, from the Carboniferous, 324 to 359 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 16×. 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. Age: Carboniferous, 324 to 359 million years old. About 11 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 5 mi of the line.
Conglomerate. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 2 mi of the line.
Chert. Age: Carboniferous, 324 to 359 million years old. About 2 mi of the line.
Shale. Age: Carboniferous, 324 to 359 million years old. About 1 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 Doyle reaches the Gulf of America by way of the Calfkiller, the Caney Fork, the Cumberland, the Ohio and the Mississippi: about 1,430 river miles.
Lake on the way: Bards Lake.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Doyle; river miles along the main stem, rounded.
Doyle has a humid subtropical climate. Summer afternoons average 88° in July; winter nights fall to about 28° in January. A normal year brings about 5 inches of snow; with the rain, that comes to about 59 inches of water.
On November 14 Doyle normally reaches 60° and falls to 36°. The record high is 78°, in 1993; the record low 17°, in 1986. The most rain on this date, 1.41 in, fell in 1957.
Normals 1991–2020 and records since 1940 at Sparta Wastewater Plant, 4 miles north-northeast. NOAA, through RCC-ACIS.
