3.15 inches of rain fell in two days, the most for this week of the year since records began in 1892. The next wettest, 3.10 inches, fell in 1978.
Bergman’s center stands about 1,260 ft above sea level. Within three miles the land runs from 1,020 ft to 1,370 ft, a difference of 350 ft: rolling country. The highest named summit within 15 miles is Boat Mountain, about 2,220 ft, 14 miles south.
Under the town center the state geologic map shows Boone Formation (limestone), from the Carboniferous, 324 to 359 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 27×. 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: Carboniferous, 324 to 359 million years old. About 14 mi of the line.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 7 mi of the line.
Sandstone, dolostone. Age: Middle Ordovician, 459 to 471 million years old. About 1 mi of the line.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 0.7 mi of the line.

A raindrop that lands in Bergman reaches the Gulf of America by way of Sugar Orchard Creek, Crooked Creek, the White River and the Mississippi: about 1,070 river miles.
620 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Bergman; river miles along the main stem, rounded.
Bergman has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 27° in January. About 44 inches of rain fall in a normal year.
On November 14 Bergman normally reaches 60° and falls to 38°. The record high is 80°, in 1955; the record low 5°, in 1908. The most rain on this date, 1.53 in, fell in 1993.
