5.82 inches of rain fell in two days, the most for this week of the year since records began in 1907. The next wettest, 5.63 inches, fell in 2011.
Tull’s center stands about 360 ft above sea level. Within three miles the land runs from 240 ft to 400 ft, a difference of 160 ft: gently rolling country. The highest named summit within 15 miles is Alexander Mountain, about 600 ft, 14 miles north-northeast.
Under the town center the state geologic map shows Terrace deposits (coarse-detrital, fine-detrital), from the Pleistocene, less than 2.6 million years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 49×. 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, fine-detrital. Age: Early Eocene, 48 to 56 million years old. About 10 mi of the line.
Coarse-detrital, fine-detrital. Age: Holocene, less than 12,000 years old. About 7 mi of the line.
Sand, clay. Age: Middle Eocene, 38 to 48 million years old. About 4 mi of the line.
Chert, shale. Age: Middle Ordovician to Late Ordovician, 445 to 471 million years old. About 2 mi of the line.
Coarse-detrital, fine-detrital. Age: Pleistocene, less than 2.6 million years old. About 1 mi of the line.
Sandstone. Age: Silurian, 422 to 445 million years old. About 0.7 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.

A raindrop that lands in Tull reaches the Gulf of America by way of the Saline, the Ouachita, the Black River, the Red River, the Atchafalaya and the Lower Atchafalaya: about 580 river miles.
190 miles of the trip are on the Ouachita.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Tull; river miles along the main stem, rounded.
Tull has a humid subtropical climate. Summer afternoons average 93° in July; winter nights fall to about 30° in January. About 53 inches of rain fall in a normal year, with about 1 inch of snow.
On November 14 Tull normally reaches 64° and falls to 41°. The record high is 80°, in 1964; the record low 14°, in 1940. The most rain on this date, 1.90 in, fell in 1959.
Normals 1991–2020 and records since 1907 at Benton, 8 miles north. NOAA, through RCC-ACIS.
