70° on Nov. 14, 1953, the hottest reading for this week of the year since 1893. Next is 70° in 2001.
Pierpont’s center stands about 1,510 ft above sea level. Within three miles the land runs from 1,390 ft to 1,600 ft, a difference of 210 ft: 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 34×. 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.

A raindrop that lands in Pierpont reaches the Gulf of America by way of Mud Creek, the James, the Missouri and the Mississippi: about 2,360 river miles.
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 Pierpont; river miles along the main stem, rounded.
Pierpont has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 2° in January. A normal year brings about 43 inches of snow; with the rain, that comes to about 26 inches of water.
On November 14 Pierpont normally reaches 40° and falls to 22°. The record high is 70°, in 1953; the record low −10°, in 1959. The most rain on this date, 0.22 in, fell in 2006.
Normals 1991–2020 and records since 1893 at Webster, 19 miles southeast, 350 ft higher. NOAA, through RCC-ACIS.
