73° on Nov. 12, 1999, the hottest reading for this week of the year since 1912. Next is 72° in 1990.
Fair Haven Colony’s center stands about 3,450 ft above sea level. Within three miles the land runs from 3,340 ft to 3,690 ft, a difference of 350 ft: rolling country. The highest named summit within 15 miles is Mount Cecelia, about 6,120 ft, 14 miles southwest.
Under the town center the state geologic map shows Bootlegger and Vaughn Members of Blackleaf Formation (black-shale, sandstone, siltstone), from the Early Cretaceous to Late Cretaceous, 94 to 113 million years old.
The section below crosses 9 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 14×. 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, shale, siltstone. Age: Early Cretaceous, 100 to 113 million years old. About 6 mi of the line.
Syenitic. Age: Cretaceous, 66 to 145 million years old. About 4 mi of the line.
Shale, limestone, dolostone. Age: Late Cretaceous, 84 to 90 million years old. About 3 mi of the line.
Black-shale, sandstone, siltstone. Age: Early Cretaceous to Late Cretaceous, 94 to 113 million years old. About 3 mi of the line.
Shale. Age: Late Cretaceous, 87 to 94 million years old. About 3 mi of the line.
Gravel, sand, silt. Age: Pleistocene to Holocene, less than 1.8 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 3 smaller units along the line are not listed.

A raindrop that lands in Fair Haven Colony reaches the Gulf of America by way of the Dry Fork, Little Muddy Creek, the Missouri and the Mississippi: about 3,330 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.

Fair Haven Colony has a cold semi-arid climate. Summer afternoons average 83° in July; winter nights fall to about 13° in January. About 13 inches of rain fall in a normal year.
On November 14 Fair Haven Colony normally reaches 45° and falls to 22°. The record high is 72°, in 1999; the record low −17°, in 2014. The most rain on this date, 0.17 in, fell in 1988.
