19° on Nov. 13, 2019, the coldest reading for this week of the year since 1975. Next is 21° in 1997.
Quinlan’s center stands about 520 ft above sea level. Within three miles the land runs from 430 ft to 530 ft, a difference of 100 ft: gently rolling country.
Under the town center the state geologic map shows Kemp clay and Corsicana Marl, undivided, from the Late Cretaceous, 66 to 72 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 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, sand. Age: Paleocene, 56 to 66 million years old. About 8 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 7 mi of the line.
Clay. Age: Late Cretaceous, 66 to 72 million years old. About 3 mi of the line.
Claystone. Age: Late Cretaceous, 66 to 72 million years old. About 3 mi of the line.
Clay. Age: Paleocene, 56 to 66 million years old. About 1 mi of the line.
Sandstone. Age: Late Cretaceous, 66 to 72 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. 1 smaller unit along the line are not listed.
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 Quinlan reaches the Gulf of America by way of Jones Creek and the Sabine: about 490 river miles.
Lakes on the way: Toledo Bend Reservoir, Sabine Lake and Lake Tawakoni.
240 miles of the trip are on the Sabine.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Quinlan; river miles along the main stem, rounded.
Quinlan has a humid subtropical climate. Summer afternoons average 94° in July; winter nights fall to about 34° in January. About 44 inches of rain fall in a normal year.
On November 14 Quinlan normally reaches 66° and falls to 44°. The record high is 84°, in 1989; the record low 22°, in 1986. The most rain on this date, 0.32 in, fell in 1993.
Normals 1991–2020 and records since 1975 at Lake Tawakoni, 15 miles east-southeast. NOAA, through RCC-ACIS.
