81° on Nov. 11, 2020, the hottest reading for this week of the year since 1948. Next is 80° in 1985.
Lenoir City’s center stands about 830 ft above sea level. Within three miles the land runs from 740 ft to 1,070 ft, a difference of 330 ft: rolling country. The highest named summit within 15 miles is Melton Hill, about 1,380 ft, 8 miles north-northwest.
Under the town center the state geologic map shows Unnamed (upper part of Knox Group), including Newala Formation, Mascot Dolomite, Kingsport Formation, Longview Dolomite, and Chepultepec Dolomite (dolostone, limestone), from the Ordovician, 445 to 487 million years old.
The section below crosses 12 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 40×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

A raindrop that lands in Lenoir City reaches the Gulf of America by way of Town Creek, the Tennessee, the Ohio and the Mississippi: about 1,610 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.
