73° on Nov. 15, 1953, the hottest reading for this week of the year since 1893. Next is 72° in 2001.
Bryant’s center stands about 1,850 ft above sea level. Within three miles the land runs from 1,770 ft to 1,870 ft, a difference of 100 ft: gently rolling country.
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 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, bentonite. Age: Late Cretaceous, 66 to 100 million years old. About 24 mi of the line.

A raindrop that lands in Bryant reaches the Gulf of America by way of Dolph Creek, the Big Sioux, the Missouri and the Mississippi: about 2,250 river miles.
Lakes on the way: Lake Poinsett and Lake Albert.
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 Bryant; river miles along the main stem, rounded.
Bryant has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 5° in January. A normal year brings about 41 inches of snow; with the rain, that comes to about 26 inches of water.
On November 14 Bryant normally reaches 41° and falls to 23°. The record high is 72°, in 1953; the record low −15°, in 1959. The most rain on this date, 0.63 in, fell in 1928.
Normals 1991–2020 and records since 1893 at De Smet, 15 miles south-southwest, 150 ft lower. NOAA, through RCC-ACIS.
