−25° on Nov. 13, 1959, the coldest reading for this week of the year since 1894. Next is −24° in 1916.
Fox’s center stands about 5,020 ft above sea level. Within three miles the land runs from 4,820 ft to 5,380 ft, a difference of 560 ft: hilly country. The highest named summit within 15 miles is Bare Mountain, about 9,900 ft, 14 miles west-southwest.
Under the town center the state geologic map shows Gravel, from the Pleistocene to Holocene, less than 1.8 million years old.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 4×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Age: Pleistocene to Holocene, less than 1.8 million years old. About 10 mi of the line.
Sandstone. Age: Late Cretaceous, 66 to 84 million years old. About 4 mi of the line.
Gneiss. Age: Archean. About 4 mi of the line.
Sandstone, shale. Age: Early Paleocene to Middle Paleocene, 59 to 66 million years old. About 3 mi of the line.
Shale, sandstone, bentonite. Age: Early Paleocene, 62 to 66 million years old. About 1 mi of the line.
Gravel, sand, silt. Age: Pleistocene to Holocene, less than 1.8 million years old. About 0.9 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 smaller units along the line are not listed.

A raindrop that lands in Fox reaches the Gulf of America by way of Rock Creek, the Clarks Fork Yellowstone, the Yellowstone, the Missouri and the Mississippi: about 3,170 river miles.
Lakes on the way: Lake Oahe, Lake Sakakawea, Lake Sharpe and Lake Francis Case.
1,170 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Fox; river miles along the main stem, rounded.
Fox has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 14° in January. A normal year brings about 142 inches of snow; with the rain, that comes to about 23 inches of water.
On November 14 Fox normally reaches 44° and falls to 22°. The record high is 66°, in 1999; the record low −20°, in 1955. The most rain on this date, 0.68 in, fell in 1993.
Normals 1991–2020 and records since 1894 at Red Lodge, 7 miles south-southwest, 630 ft higher. NOAA, through RCC-ACIS.
