12° on Nov. 13, 2019, the coldest reading for this week of the year since 1957. Next is 15° in 1969.
Dellrose’s center stands about 650 ft above sea level. Within three miles the land runs from 610 ft to 980 ft, a difference of 370 ft: rolling country. The highest named summit within 15 miles is Gould Hill, about 1,230 ft, 14 miles north-northeast.
Under the town center the state geologic map shows Ordovician [units] including Richmond Group (which includes Mannie Shale, Fernvale Limestone, Sequatchie Formation, and Arnheim Formation), the Maysville Group (which includes Leipers Formation), the Eden Group (which includes Inman Formation), and the Nashville Group (which includes Catheys Formation) (shale, limestone), from the Ordovician, 445 to 487 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 38×. 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, limestone. Age: Ordovician, 445 to 487 million years old. About 10 mi of the line.
Limestone, calcarenite. Age: Ordovician, 445 to 487 million years old. About 5 mi of the line.
Chert. Age: Carboniferous, 324 to 359 million years old. About 5 mi of the line.
Limestone, siltstone. Age: Carboniferous, 324 to 359 million years old. About 3 mi of the line.
Fine-detrital, coarse-detrital. Age: Quaternary, less than 2.6 million years old. About 0.7 mi of the line.
Limestone. Age: Silurian, 422 to 445 million years old. About 0.3 mi of the line.

A raindrop that lands in Dellrose reaches the Gulf of America by way of the Elk River, the Tennessee, the Ohio and the Mississippi: about 1,360 river miles.
Lakes on the way: Guntersville Lake, White Lake (historical) and Pickwick 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 Dellrose; river miles along the main stem, rounded.
Dellrose has a humid subtropical climate. Summer afternoons average 88° in July; winter nights fall to about 25° in January. About 59 inches of rain fall in a normal year, with about 2 inches of snow.
On November 14 Dellrose normally reaches 61° and falls to 33°. The record high is 80°, in 1964; the record low 12°, in 2019. The most rain on this date, 1.21 in, fell in 1957.
Normals 1991–2020 and records since 1957 at Pulaski Wastewater Plant, 14 miles west-northwest. NOAA, through RCC-ACIS.
