76° on Nov. 12, 1999, the hottest reading for this week of the year since 1893. Next is 75° in 1990.
Camp Crook’s center stands about 3,120 ft above sea level. Within three miles the land runs from 3,090 ft to 3,260 ft, a difference of 170 ft: gently rolling country. The highest named summit within 15 miles is Sheep Mountain, about 4,050 ft, 12 miles west-southwest.
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 20×. 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. Age: Late Cretaceous, 66 to 100 million years old. About 9 mi of the line.
Coarse-detrital, fine-detrital. Age: Quaternary, less than 2.6 million years old. About 6 mi of the line.
Sandstone, bentonite. Age: Late Eocene to Late Oligocene, 23 to 38 million years old. About 6 mi of the line.
Sandstone, mudstone. Age: Early Paleocene, 62 to 66 million years old. About 2 mi of the line.
Coarse-detrital, clay. Age: Quaternary, less than 2.6 million years old. About 1 mi of the line.
Sandstone, shale, bentonite. Age: Late Cretaceous, 66 to 84 million years old. About 0.6 mi of the line.

A raindrop that lands in Camp Crook reaches the Gulf of America by way of the Little Missouri, the Missouri and the Mississippi: about 3,020 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.

Camp Crook has a cold semi-arid climate. Summer afternoons average 88° in July; winter nights fall to about 10° in January. A normal year brings about 50 inches of snow; with the rain, that comes to about 16 inches of water.
On November 14 Camp Crook normally reaches 47° and falls to 22°. The record high is 75°, in 1990; the record low −22°, in 1959. The most rain on this date, 0.64 in, fell in 1964.
