6.48 inches of rain fell in two days, the most for this week of the year since records began in 1941. The next wettest, 4.12 inches, fell in 1958.
Pleasant Grove’s center stands about 460 ft above sea level. Within three miles the land runs from 270 ft to 1,190 ft, a difference of 920 ft: steep hill country. The highest named summit within 15 miles is Irons Mountain, about 1,600 ft, 6 miles west-northwest.
Under the town center the state geologic map shows Pitkin Limestone, Fayetteville Shale (including the Wedington Sandstone member), and Batesville Sandstone (including the Hindsville Limestone Member) (sandstone, shale, limestone), from the Carboniferous, 324 to 359 million years old.

Sandstone, shale, limestone. Age: Carboniferous, 324 to 359 million years old. About 14 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 6 mi of the line.
Shale. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.
Coarse-detrital, fine-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 2 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 1 mi of the line.
Shale. Age: Carboniferous, 324 to 359 million years old. About 0.3 mi of the line.

A raindrop that lands in Pleasant Grove reaches the Gulf of America by way of Alder Creek, the White River and the Mississippi: about 930 river miles.
620 miles of the trip are on the Mississippi.

Pleasant Grove has a humid subtropical climate. Summer afternoons average 88° in July; winter nights fall to about 26° in January. About 50 inches of rain fall in a normal year, with about 4 inches of snow.
On November 14 Pleasant Grove normally reaches 58° and falls to 37°. The record high is 86°, in 1955; the record low 16°, in 1986. The most rain on this date, 1.91 in, fell in 1958.
