10° on Nov. 17, 2014, the coldest reading for this week of the year since 1906. Next is 11° in 2019.
Nescatunga’s center stands about 1,150 ft above sea level. Within three miles the land runs from 1,100 ft to 1,250 ft, a difference of 150 ft: gently rolling country.
Under the town center the state geologic map shows Terrace Deposits (coarse-detrital, fine-detrital), from the Pleistocene, less than 2.6 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Coarse-detrital, fine-detrital. Age: Pleistocene, less than 2.6 million years old. About 16 mi of the line.
Shale, sandstone, siltstone. Age: Permian, 252 to 299 million years old. About 2 mi of the line.
Shale, sandstone, siltstone. Age: Permian, 252 to 299 million years old. About 2 mi of the line.
Sandstone, shale. Age: Permian, 252 to 299 million years old. About 1 mi of the line.
Fine-detrital. Age: Holocene, less than 12,000 years old. About 0.7 mi of the line.

A raindrop that lands in Nescatunga reaches the Gulf of America by way of Great Salt Plains Reservoir, the Salt Fork Arkansas, the Arkansas and the Mississippi: about 1,300 river miles.
Lakes on the way: Great Salt Plains Reservoir, Murray Lake and Ozark 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 Nescatunga; river miles along the main stem, rounded.
Nescatunga has a humid subtropical climate. Summer afternoons average 95° in July; winter nights fall to about 23° in January. A normal year brings about 13 inches of snow; with the rain, that comes to about 32 inches of water.
On November 14 Nescatunga normally reaches 60° and falls to 36°. The record high is 82°, in 1999; the record low 12°, in 2018. The most rain on this date, 0.66 in, fell in 1985.
Normals 1991–2020 and records since 1906 at Helena 1 SSE, 16 miles south-southwest, 200 ft higher. NOAA, through RCC-ACIS.
