13° on Nov. 14, 1986, the coldest reading for this week of the year since 1891. Next is 13° in 2019.
Lavalette’s center stands about 570 ft above sea level. Within three miles the land runs from 560 ft to 980 ft, a difference of 420 ft: hilly country. The highest named summit within 15 miles is Buck Knob, about 1,270 ft, 13 miles south-southeast.
Under the town center the state geologic map shows Conemaugh Group (shale, siltstone, sandstone), from the Carboniferous, 299 to 324 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 29×. 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, siltstone, sandstone. Age: Carboniferous, 299 to 324 million years old. About 18 mi of the line.
Shale, siltstone. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Fine-detrital, coarse-detrital. Age: Quaternary, less than 2.6 million years old. About 1 mi of the line.
Shale, siltstone, mudstone. Age: Carboniferous, 299 to 324 million years old. About 1 mi of the line.
Sandstone, siltstone, shale. Age: Carboniferous, 299 to 324 million years old. About 0.3 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Lavalette reaches the Gulf of America by way of Twelvepole Creek, the Ohio and the Mississippi: about 1,650 river miles.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lavalette; river miles along the main stem, rounded.
Lavalette has a humid subtropical climate. Summer afternoons average 86° in July; winter nights fall to about 26° in January. A normal year brings about 20 inches of snow; with the rain, that comes to about 45 inches of water.
On November 14 Lavalette normally reaches 57° and falls to 37°. The record high is 82°, in 1993; the record low 13°, in 1986. The most rain on this date, 1.51 in, fell in 2024.
Normals 1991–2020 and records since 1891 from the Huntington Area threaded record (Huntington Tri-State Airport, 7 miles west-northwest, 250 ft higher). NOAA, through RCC-ACIS.
