80° on Nov. 11, 2020, the hottest reading for this week of the year since 1962. Next is 78° in 1989.
Niota’s center stands about 960 ft above sea level. Within three miles the land runs from 860 ft to 1,220 ft, a difference of 360 ft: rolling country. The highest named summit within 15 miles is Roy Knob, about 1,570 ft, 6 miles east.
The section below crosses 9 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 31×. 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, limestone. Age: Ordovician, 445 to 487 million years old. About 7 mi of the line.
Shale. Age: Cambrian, 487 to 542 million years old. About 6 mi of the line.
Dolostone. Age: Cambrian, 487 to 542 million years old. About 4 mi of the line.
Limestone. Age: Ordovician, 445 to 487 million years old. About 3 mi of the line.
Limestone. Age: Ordovician, 445 to 487 million years old. About 2 mi of the line.
Dolostone, limestone. Age: Cambrian to Ordovician, 445 to 542 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. 3 smaller units along the line are not listed.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Niota reaches the Gulf of America by way of Little North Mouse Creek, North Mouse Creek, the Hiwassee, the Tennessee, the Ohio and the Mississippi: about 1,560 river miles.
Lakes on the way: Guntersville Lake, White Lake (historical), Pickwick Lake and Cummings 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 Niota; river miles along the main stem, rounded.
Niota has a humid subtropical climate. Summer afternoons average 88° in July; winter nights fall to about 28° in January. About 60 inches of rain fall in a normal year, with about 4 inches of snow.
On November 14 Niota normally reaches 61° and falls to 36°. The record high is 76°, in 1989; the record low 18°, in 2019. The most rain on this date, 0.76 in, fell in 1972.
Normals 1991–2020 and records since 1962 at Athens, 6 miles south-southwest. NOAA, through RCC-ACIS.
