Ayr’s center stands about 1,830 ft above sea level. Within three miles the land runs from 1,790 ft to 1,920 ft, a difference of 130 ft: gently rolling country.
Under the town center the state geologic map shows Niobrara Formation (limestone, shale), from the Late Cretaceous, 66 to 100 million years old.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone, shale. Age: Late Cretaceous, 66 to 100 million years old. About 24 mi of the line.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 0.4 mi of the line.

A raindrop that lands in Ayr reaches the Gulf of America by way of the Little Blue, the Big Blue, the Kansas, the Missouri and the Mississippi: about 1,910 river miles.
Lake on the way: Tuttle Creek Lake.
1,170 miles of the trip are on the Mississippi.
