Millerdale Colony’s center stands about 1,920 ft above sea level. Within three miles the land runs from 1,860 ft to 2,090 ft, a difference of 230 ft: rolling country. The highest named summit within 15 miles is Ree Hills, about 2,140 ft, 7 miles north-northwest.
Under the town center the state geologic map shows Pierre Shale (shale, bentonite), from the Late Cretaceous, 66 to 100 million years old.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 42×. 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, bentonite. Age: Late Cretaceous, 66 to 100 million years old. About 24 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

Millerdale Colony has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 7° in January. A normal year brings about 44 inches of snow; with the rain, that comes to about 22 inches of water.
On November 14 Millerdale Colony normally reaches 44° and falls to 23°. The record high is 73°, in 1990; the record low −17°, in 1940. The most rain on this date, 0.52 in, fell in 1928.
Normals 1991–2020 and records since 1902 at Miller, 10 miles northeast, 340 ft lower. NOAA, through RCC-ACIS.
