25° on Nov. 14, 2014, the coldest reading for this week of the year since 1966. Next is 26° in 1989.
Doyline’s center stands about 230 ft above sea level. Within three miles the land runs from 170 ft to 300 ft, a difference of 130 ft: gently rolling country. The highest named summit within 15 miles is Giddens Hill, about 420 ft, 7 miles west.
Under the town center the state geologic map shows Intermediate Terraces (clay, silt), from the Pleistocene, less than 2.6 million years old.
The section below crosses 6 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.
Clay. Age: Holocene, less than 12,000 years old. About 7 mi of the line.
Clay, silt. Age: Pleistocene, less than 2.6 million years old. About 6 mi of the line.
Clay, silt, sand. Age: Pleistocene, less than 2.6 million years old. About 4 mi of the line.
Clay, silt, sand. Age: Pleistocene, less than 2.6 million years old. About 3 mi of the line.
Clay, silt. Age: Eocene, 34 to 56 million years old. About 2 mi of the line.
Sand, clay, lignite. Age: Paleocene, 56 to 66 million years old. About 1 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 Doyline reaches the Gulf of America by way of Prairie Bayou, Loggy Bayou, the Red River, the Atchafalaya and the Lower Atchafalaya: about 400 river miles.
Lake on the way: Tadpole Lake.
230 miles of the trip are on the Red River.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Doyline; river miles along the main stem, rounded.
Doyline has a humid subtropical climate. Summer afternoons average 94° in August; winter nights fall to about 36° in January. About 52 inches of rain fall in a normal year.
On November 14 Doyline normally reaches 68° and falls to 45°. The record high is 85°, in 1993; the record low 25°, in 2014. The most rain on this date, 1.13 in, fell in 1970.
Normals 1991–2020 and records since 1966 at Red River Research Station, 15 miles west-southwest. NOAA, through RCC-ACIS.
