5.62 inches of rain fell in two days, the most for this week of the year since records began in 1905. The next wettest, 4.65 inches, fell in 1971.
Pittsburg’s center stands about 390 ft above sea level. Within three miles the land runs from 300 ft to 450 ft, a difference of 150 ft: gently rolling country. The highest named summit within 15 miles is Howell Mountain, about 610 ft, 10 miles south-southeast.
Under the town center the state geologic map shows Reklaw Formation (sandstone), from the Eocene, 34 to 56 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone. Age: Eocene, 34 to 56 million years old. About 14 mi of the line.
Siltstone, sandstone. Age: Middle Eocene, 38 to 48 million years old. About 5 mi of the line.
Sandstone. Age: Eocene, 34 to 56 million years old. About 3 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 1 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.3 mi of the line.

A raindrop that lands in Pittsburg reaches the Gulf of America by way of Sparks Branch, Dry Creek, Big Cypress Creek, Big Cypress Bayou, Twelvemile Bayou, Cross Bayou, the Red River, the Atchafalaya and the Lower Atchafalaya: about 530 river miles.
Lakes on the way: Clear Lake and Lake O' the Pines.
260 miles of the trip are on the Red River.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Pittsburg; river miles along the main stem, rounded.
Pittsburg has a humid subtropical climate. Summer afternoons average 94° in August; winter nights fall to about 32° in January. About 49 inches of rain fall in a normal year, with about 2 inches of snow.
On November 14 Pittsburg normally reaches 66° and falls to 41°. The record high is 88°, in 2005; the record low 17°, in 1940. The most rain on this date, 2.12 in, fell in 1958.
Normals 1991–2020 and records since 1905 at Mount Pleasant, 12 miles north-northwest. NOAA, through RCC-ACIS.
