74° on Nov. 11, 1904, the hottest reading for this week of the year since 1896. Next is 74° in 1905.
Milford Colony’s center stands about 4,220 ft above sea level. Within three miles the land runs from 4,130 ft to 4,610 ft, a difference of 480 ft: hilly country. The highest named summit within 15 miles is Table Mountain, about 7,140 ft, 12 miles west-southwest.
Under the town center the state geologic map shows Alluvium (gravel, sand, silt), from the Pleistocene to Holocene, less than 1.8 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 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.
Volcanic. Age: Late Cretaceous, 66 to 84 million years old. About 12 mi of the line.
Sandstone, siltstone, mudstone. Age: Late Cretaceous, 66 to 84 million years old. About 6 mi of the line.
Sandstone. Age: Late Cretaceous, 72 to 84 million years old. About 2 mi of the line.
Gravel, sand, silt. Age: Pleistocene to Holocene, less than 1.8 million years old. About 1 mi of the line.
Shale, dolostone, limestone. Age: Late Cretaceous, 84 to 100 million years old. About 1 mi of the line.
Dolostone, limestone, shale. Age: Middle Cambrian to Cambrian, 487 to 521 million years old. About 0.6 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 Milford Colony reaches the Gulf of America by way of Flat Creek, the Dearborn, the Missouri and the Mississippi: about 3,390 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.

Milford Colony has a cold semi-arid climate. Summer afternoons average 82° in July; winter nights fall to about 16° in February. About 16 inches of rain fall in a normal year.
On November 14 Milford Colony normally reaches 45° and falls to 26°. The record high is 71°, in 1936; the record low −26°, in 1909. The most rain on this date, 0.25 in, fell in 1988.
Normals 1991–2020 and records since 1896 at Augusta, 14 miles northwest, 150 ft lower. NOAA, through RCC-ACIS.
