4.63 inches of rain fell in two days, the most for this week of the year since records began in 1901. The next wettest, 3.42 inches, fell in 2005.
Hartville’s center stands about 1,230 ft above sea level. Within three miles the land runs from 1,130 ft to 1,500 ft, a difference of 370 ft: rolling country. The highest named summit within 15 miles is Lead Hill, about 1,760 ft, 12 miles south-southwest.

Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 16 mi of the line.
Sandstone, chert. Age: Early Ordovician, 471 to 487 million years old. About 8 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 0.6 mi of the line.

A raindrop that lands in Hartville reaches the Gulf of America by way of the Gasconade, the Missouri and the Mississippi: about 1,530 river miles.
1,170 miles of the trip are on the Mississippi.

Hartville has a hot-summer humid continental climate. Summer afternoons average 87° in July; winter nights fall to about 22° in January. A normal year brings about 10 inches of snow; with the rain, that comes to about 46 inches of water.
On November 14 Hartville normally reaches 56° and falls to 36°. The record high is 79°, in 1999; the record low 5°, in 1986. The most rain on this date, 2.05 in, fell in 1993.
