87° on Nov. 13, 1955, the hottest reading for this week of the year since 1884. Next is 84° in 1941.
Sherrill’s center stands about 220 ft above sea level. Within three miles the land runs from 200 ft to 250 ft, a difference of 50 ft: nearly flat ground. The highest named summit within 15 miles is Sanders Hill, about 450 ft, 12 miles west.
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.
Coarse-detrital, fine-detrital. Age: Holocene, less than 12,000 years old. About 17 mi of the line.
Marl. Age: Late Eocene, 34 to 38 million years old. About 3 mi of the line.
Coarse-detrital, fine-detrital. Age: Holocene, less than 12,000 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.
Coarse-detrital, fine-detrital. Age: Holocene, less than 12,000 years old. About 0.4 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Sherrill reaches the Gulf of America by way of Plum Bayou, the Arkansas and the Mississippi: about 700 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Sherrill; river miles along the main stem, rounded.
Sherrill has a humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 34° in January. About 51 inches of rain fall in a normal year.
On November 14 Sherrill normally reaches 63° and falls to 42°. The record high is 87°, in 1955; the record low 19°, in 1907. The most rain on this date, 2.45 in, fell in 1922.
Normals 1991–2020 and records since 1884 from the Pine Bluff Area threaded record (Pine Bluff Grider Field, 14 miles south). NOAA, through RCC-ACIS.
