73° on Nov. 17, 1953, the hottest reading for this week of the year since 1881. Next is 68° in 1934.
Frontier’s center stands about 910 ft above sea level. Within three miles the land runs from 890 ft to 920 ft, a difference of 30 ft: nearly flat ground.
Under the town center the state geologic map shows Belle Fourche-Skull Creek, Undivided (shale, sandstone), from the Early Cretaceous to Late Cretaceous, 66 to 145 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 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. Age: Early Cretaceous to Late Cretaceous, 66 to 145 million years old. About 13 mi of the line.
Age: Precambrian. About 7 mi of the line.
Granitic. Age: Neoarchean, 2.5 to 2.8 billion years old. About 4 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 Frontier reaches Hudson Bay by way of the Red River of the North and the Nelson: about 1,110 river miles. Past the border it runs north through Canada to Hudson Bay.
Lake on the way: Lake Winnipeg.
460 miles of the trip are on the Red River of the North.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Frontier; river miles along the main stem, rounded.
Frontier has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 0° in January. A normal year brings about 51 inches of snow; with the rain, that comes to about 24 inches of water.
On November 14 Frontier normally reaches 39° and falls to 22°. The record high is 66°, in 1939; the record low −9°, in 1919. The most rain on this date, 1.26 in, fell in 1909.
