75° on Nov. 13, 1999, the hottest reading for this week of the year since 1959. Next is 72° in 1989.
Hulett’s center stands about 3,780 ft above sea level. Within three miles the land runs from 3,710 ft to 4,330 ft, a difference of 620 ft: hilly country. The highest named summit within 15 miles is Sherrard Hill, about 5,380 ft, 10 miles south-southeast.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 12×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone, claystone. Age: Late Jurassic to Early Cretaceous, 100 to 164 million years old. About 12 mi of the line.
Sandstone, shale, dolostone. Age: Middle Jurassic to Late Jurassic, 145 to 175 million years old. About 9 mi of the line.
Sandstone, shale. Age: Early Cretaceous, 100 to 145 million years old. About 1 mi of the line.
Clay, silt, sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.8 mi of the line.
Sandstone, siltstone, claystone. Age: Late Oligocene to Late Miocene, 5.3 to 28 million years old. About 0.8 mi of the line.
Claystone, conglomerate. Age: Late Eocene to Early Oligocene, 31 to 35 million years old. About 0.4 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 Hulett reaches the Gulf of America by way of the Belle Fourche, the Cheyenne, the Missouri and the Mississippi: about 2,670 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.

Hulett has a warm-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 8° in January. A normal year brings about 49 inches of snow; with the rain, that comes to about 19 inches of water.
On November 14 Hulett normally reaches 46° and falls to 20°. The record high is 73°, in 1999; the record low −16°, in 2014. The most rain on this date, 0.46 in, fell in 1964.
Normals 1991–2020 and records since 1959 at Devils Tower No 2, 9 miles southwest. NOAA, through RCC-ACIS.
