The Rustic Acres 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.
75° on Nov. 14, 1999, the hottest reading for this week of the year since 1961. Next is 72° in 2001.
Rustic Acres Colony’s center stands about 1,740 ft above sea level. Within three miles the land runs from 1,660 ft to 1,800 ft, a difference of 140 ft: gently rolling country.
Under the town center the state geologic map shows Niobrara Formation (chalk, marlstone, shale), from the Late Cretaceous, 66 to 100 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 55×. 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 7 mi of the line.
Quartzite. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 7 mi of the line.
Chalk, marlstone, shale. Age: Late Cretaceous, 66 to 100 million years old. About 5 mi of the line.
Chert, shale, chalk. Age: Early Cretaceous to Late Cretaceous, 66 to 145 million years old. About 5 mi of the line.

A raindrop that lands in Rustic Acres Colony reaches the Gulf of America by way of North Buffalo Creek, Buffalo Creek, Skunk Creek, the Big Sioux, the Missouri and the Mississippi: about 2,130 river miles.
1,170 miles of the trip are on the Mississippi.
