Millstone’s center stands about 1,540 ft above sea level. Within three miles the land runs from 1,240 ft to 1,960 ft, a difference of 720 ft: hilly country. The highest named summit within 15 miles is Halls Butt, about 3,070 ft, 10 miles south-southwest.
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 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 9×. 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 16 mi of the line.
Sandstone, shale. Age: Carboniferous, 299 to 324 million years old. About 5 mi of the line.
Conglomerate. Age: Carboniferous, 324 to 359 million years old. About 2 mi of the line.
Limestone. Age: Devonian to Carboniferous, 299 to 422 million years old. About 0.7 mi of the line.

A raindrop that lands in Millstone reaches the Gulf of America by way of the North Fork Kentucky, the Kentucky, the Ohio and the Mississippi: about 1,820 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 Millstone; river miles along the main stem, rounded.
Millstone has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 22° in January. A normal year brings about 38 inches of snow; with the rain, that comes to about 49 inches of water.
On November 14 Millstone normally reaches 56° and falls to 30°. The record high is 72°, in 1994; the record low 12°, in 2019. The most rain on this date, 0.35 in, fell in 2005.
Normals 1991–2020 and records since 1993 at Clintwood 1 W, 14 miles east. NOAA, through RCC-ACIS.
