3.41 inches of rain fell in two days, the most for this week of the year since records began in 1901. The next wettest, 2.76 inches, fell in 1938.
Greensburg’s center stands about 960 ft above sea level. Within three miles the land runs from 870 ft to 1,010 ft, a difference of 140 ft: gently rolling country.
Under the town center the state geologic map shows Muscatatuck Group (limestone, dolostone), from the Devonian, 359 to 422 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 59×. 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. Age: Silurian, 422 to 445 million years old. About 16 mi of the line.
Limestone, dolostone. Age: Devonian, 359 to 422 million years old. About 8 mi of the line.

A raindrop that lands in Greensburg reaches the Gulf of America by way of Muddy Fork Sand Creek, Sand Creek, the East Fork White, the White River, Big Bayou, the Wabash River Old Channel, the Old Channel Wabash, the Ohio and the Mississippi: about 1,460 river miles.
970 miles of the trip are on the Mississippi.

Greensburg has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 19° in January. A normal year brings about 16 inches of snow; with the rain, that comes to about 46 inches of water.
On November 14 Greensburg normally reaches 51° and falls to 33°. The record high is 77°, in 1955; the record low 12°, in 1986. The most rain on this date, 1.97 in, fell in 1972.
