Coffee Creek’s center stands about 3,610 ft above sea level. Within three miles the land runs from 3,570 ft to 3,850 ft, a difference of 280 ft: rolling country. The highest named summit within 15 miles is Square Butte, about 5,720 ft, 11 miles northwest.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 9×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Age: Late Miocene to Holocene, less than 7.2 million years old. About 11 mi of the line.
Shale, dolostone, limestone. Age: Late Cretaceous, 84 to 100 million years old. About 6 mi of the line.
Shale, limestone, dolostone. Age: Late Cretaceous, 84 to 90 million years old. About 5 mi of the line.
Syenitic. Age: Tertiary, 2.6 to 66 million years old. About 2 mi of the line.
Sandstone, shale, siltstone. Age: Late Cretaceous, 72 to 87 million years old. About 1 mi of the line.

A raindrop that lands in Coffee Creek reaches the Gulf of America by way of Coffee Creek, Arrow Creek, the Missouri and the Mississippi: about 3,210 river miles.
Lakes on the way: Lake Oahe, Lake Sakakawea, Lake Fort Peck and Lake Sharpe.
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 Coffee Creek; river miles along the main stem, rounded.
Coffee Creek has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 16° in January. About 17 inches of rain fall in a normal year.
On November 14 Coffee Creek normally reaches 46° and falls to 23°. The record high is 74°, in 1999; the record low −12°, in 2014. The most rain on this date, 0.08 in, fell in 2008.
Normals 1991–2020 and records since 1965 at Stanford, 15 miles south-southwest, 680 ft higher. NOAA, through RCC-ACIS.
