−17° on Nov. 16, 1955, the coldest reading for this week of the year since 1943. Next is −17° in 1959.
Braddock’s center stands about 1,860 ft above sea level. Within three miles the land runs from 1,830 ft to 1,950 ft, a difference of 120 ft: gently rolling country.
Under the town center the state geologic map shows Fox Hills Formation (shale, sandstone), from the Late Cretaceous, 66 to 100 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 55×. 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: Late Cretaceous, 66 to 100 million years old. About 21 mi of the line.
Sandstone, siltstone, claystone. Age: Late Cretaceous, 66 to 100 million years old. About 2 mi of the line.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 1 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 Braddock reaches the Gulf of America by way of Goose Creek, Long Lake Creek, Random Creek, Apple Creek, the Missouri and the Mississippi: about 2,570 river miles.
Lakes on the way: Lake Oahe, Lake Sharpe, Lake Francis Case and Lewis and Clark Lake.
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 Braddock; river miles along the main stem, rounded.
Braddock has a cold desert climate. Summer afternoons average 84° in July; winter nights fall to about 2° in January. Barely 0.0 inches of rain fall in a normal year.
On November 14 Braddock normally reaches 41° and falls to 21°. The record high is 69°, in 1953; the record low −8°, in 1955. The most rain on this date, 0.70 in, fell in 1944.
Normals 1991–2020 and records since 1943 at Moffit 3 SE, 10 miles northwest, 120 ft lower. NOAA, through RCC-ACIS.
