13° on Nov. 17, 1959, the coldest reading for this week of the year since 1897. Next is 15° in 1940.
Subiaco’s center stands about 470 ft above sea level. Within three miles the land runs from 380 ft to 1,070 ft, a difference of 690 ft: hilly country. The highest named summit within 15 miles is Signal Hill, about 2,760 ft, 9 miles south.
Under the town center the state geologic map shows Savanna Formation (shale, sandstone), from the Carboniferous, 299 to 324 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 9×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 6 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 5 mi of the line.
Sandstone, shale. Age: Carboniferous, 299 to 324 million years old. About 5 mi of the line.
Coarse-detrital, fine-detrital. Age: Holocene, less than 12,000 years old. About 3 mi of the line.
Shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.
Sandstone, black-shale. Age: Carboniferous, 299 to 324 million years old. About 0.8 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 Subiaco reaches the Gulf of America by way of Hegwood Creek, the Arkansas and the Mississippi: about 870 river miles.
Lake on the way: Murray Lake.
600 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Subiaco; river miles along the main stem, rounded.
Subiaco has a humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 28° in January. About 49 inches of rain fall in a normal year, with about 2 inches of snow.
On November 14 Subiaco normally reaches 62° and falls to 39°. The record high is 86°, in 1955; the record low 17°, in 2019. The most rain on this date, 1.78 in, fell in 1915.
