81° on Nov. 14, 1993, the hottest reading for this week of the year since 1937. Next is 78° in 1945.
Hiltons’s center stands about 1,320 ft above sea level. Within three miles the land runs from 1,270 ft to 3,010 ft, a difference of 1,740 ft: steep hill country. The highest named summit within 15 miles is Big Knob, about 3,160 ft, 2 miles west-northwest.
Under the town center the state geologic map shows Brallier Formation (shale, sandstone), from the Devonian, 359 to 422 million years old.
The section below crosses 16 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 11×. 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: Cambrian to Ordovician, 445 to 542 million years old. About 5 mi of the line.
Shale, sandstone, mudstone. Age: Carboniferous, 324 to 359 million years old. About 4 mi of the line.
Shale, dolostone. Age: Cambrian, 487 to 542 million years old. About 3 mi of the line.
Shale. Age: Cambrian, 487 to 542 million years old. About 2 mi of the line.
Shale. Age: Ordovician, 445 to 487 million years old. About 2 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 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. 10 smaller units along the line are not listed.

A raindrop that lands in Hiltons reaches the Gulf of America by way of the North Fork Holston, the Holston, the Tennessee, the Ohio and the Mississippi: about 1,820 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 Hiltons; river miles along the main stem, rounded.
Hiltons has a humid subtropical climate. Summer afternoons average 86° in July; winter nights fall to about 26° in January. A normal year brings about 9 inches of snow; with the rain, that comes to about 44 inches of water.
On November 14 Hiltons normally reaches 59° and falls to 34°. The record high is 81°, in 1993; the record low 16°, in 1986. The most rain on this date, 0.62 in, fell in 1945.
Normals 1991–2020 and records since 1937 from the Bristol-Johnson City Area threaded record (Bristol Airport, 13 miles south-southeast, 180 ft higher). NOAA, through RCC-ACIS.
