The Platte Colony plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
83° on Nov. 15, 2025, the hottest reading for this week of the year since 1898. Next is 81° in 1953.
Platte Colony’s center stands about 1,720 ft above sea level. Within three miles the land runs from 1,350 ft to 1,840 ft, a difference of 490 ft: hilly country. The highest named summit within 15 miles is Twin Butte, about 2,010 ft, 7 miles west-northwest.
Under the town center the state geologic map shows Pierre Shale (shale, bentonite), from the Late Cretaceous, 66 to 100 million years old.
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 25×. 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, bentonite. Age: Late Cretaceous, 66 to 100 million years old. About 18 mi of the line.
Silt, sand. Age: Quaternary, less than 2.6 million years old. About 3 mi of the line.
Coarse-detrital, fine-detrital. Age: Quaternary, less than 2.6 million years old. About 0.5 mi of the line.
Sandstone, limestone, siltstone. Age: Miocene to Pliocene, 2.6 to 23 million years old. About 0.5 mi of the line.
Fine-detrital, siltstone, conglomerate-sandstone. Age: Miocene to Pliocene, 2.6 to 23 million years old. About 0.4 mi of the line.

A raindrop that lands in Platte Colony reaches the Gulf of America by way of Snake Creek, the Missouri and the Mississippi: about 2,090 river miles.
Lakes on the way: Lake Francis Case and Lewis and Clark Lake.
1,170 miles of the trip are on the Mississippi.

Platte Colony has a hot-summer humid continental climate. Summer afternoons average 87° in July; winter nights fall to about 10° in January. A normal year brings about 42 inches of snow; with the rain, that comes to about 24 inches of water.
On November 14 Platte Colony normally reaches 47° and falls to 25°. The record high is 78°, in 1953; the record low −20°, in 1959. The most rain on this date, 0.80 in, fell in 1928.
