London Mills’s center stands about 540 ft above sea level. Within three miles the land runs from 520 ft to 670 ft, a difference of 150 ft: gently rolling country. The highest named summit within 15 miles is Haney Hill, about 760 ft, 5 miles southwest.
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 64×. 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, sandstone, coal. Age: Middle Pennsylvanian to Late Pennsylvanian, 304 to 315 million years old. About 13 mi of the line.
Shale, sandstone. Age: Early Pennsylvanian to Middle Pennsylvanian, 307 to 324 million years old. About 8 mi of the line.
Shale, limestone. Age: Late Pennsylvanian, 304 to 307 million years old. About 2 mi of the line.

London Mills has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 14° in January. A normal year brings about 25 inches of snow; with the rain, that comes to about 40 inches of water.
On November 14 London Mills normally reaches 50° and falls to 31°. The record high is 71°, in 2011; the record low 12°, in 1900. The most rain on this date, 0.45 in, fell in 1902.
