The Dwale plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
14° on Nov. 13, 2019, the coldest reading for this week of the year since 1911. Next is 16° in 1986.
Dwale’s center stands about 1,000 ft above sea level. Within three miles the land runs from 630 ft to 1,360 ft, a difference of 730 ft: hilly country. The highest named summit within 15 miles is Rough Knob, about 1,740 ft, 12 miles south.
Under the town center the state geologic map shows Breathitt Formation, lower part (shale, siltstone), from the Carboniferous, 299 to 324 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 21×. 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. Age: Carboniferous, 299 to 324 million years old. About 15 mi of the line.
Sandstone, shale. Age: Carboniferous, 299 to 324 million years old. About 6 mi of the line.
Sand, silt. Age: Pleistocene to Holocene, less than 2.6 million years old. About 3 mi of the line.

A raindrop that lands in Dwale reaches the Gulf of America by way of the Levisa Fork, the Ohio and the Mississippi: about 1,720 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 Dwale; river miles along the main stem, rounded.
Dwale has a humid subtropical climate. Summer afternoons average 86° in July; winter nights fall to about 23° in January. About 46 inches of rain fall in a normal year.
On November 14 Dwale normally reaches 59° and falls to 32°. The record high is 84°, in 1993; the record low 14°, in 2019. The most rain on this date, 1.44 in, fell in 2007.
