7.72 inches of rain fell in two days, the most for this week of the year since records began in 1893. The next wettest, 5.37 inches, fell in 1929.
Pattison’s center stands about 200 ft above sea level. Within three miles the land runs from 110 ft to 290 ft, a difference of 180 ft: gently rolling country. The highest named summit within 15 miles is Blue Hill, about 490 ft, 9 miles south.
Under the town center the state geologic map shows Catahoula formation (sand), from the Miocene, 5.3 to 23 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 52×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sand. Age: Miocene, 5.3 to 23 million years old. About 22 mi of the line.
Clay, sand. Age: Miocene, 5.3 to 23 million years old. About 2 mi of the line.
Sand, gravel. Age: Pliocene to Pleistocene, less than 5.3 million years old. About 0.5 mi of the line.

A raindrop that lands in Pattison reaches the Gulf of America by way of the Little Bayou Pierre, the Bayou Pierre and the Mississippi: about 440 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Pattison; river miles along the main stem, rounded.
Pattison has a humid subtropical climate. Summer afternoons average 93° in July; winter nights fall to about 36° in January. About 56 inches of rain fall in a normal year.
On November 14 Pattison normally reaches 69° and falls to 43°. The record high is 89°, in 1921; the record low 20°, in 1907. The most rain on this date, 2.93 in, fell in 1957.
