20° on Nov. 13, 2019, the coldest reading for this week of the year since 1985. Next is 21° in 1986.
Briaroaks’s center stands about 740 ft above sea level. Within three miles the land runs from 680 ft to 860 ft, a difference of 180 ft: gently rolling country. The highest named summit within 15 miles is Caddo Peak, about 1,030 ft, 6 miles west-southwest.
Under the town center the state geologic map shows Woodbine Formation (sandstone-mudstone), from the Late Cretaceous, 66 to 100 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 50×. 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-mudstone. Age: Late Cretaceous, 66 to 100 million years old. About 9 mi of the line.
Marlstone, limestone. Age: Early Cretaceous to Late Cretaceous, 66 to 145 million years old. About 8 mi of the line.
Black-shale, siltstone. Age: Late Cretaceous, 66 to 100 million years old. About 5 mi of the line.
Clay. Age: Early Cretaceous, 100 to 145 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Briaroaks reaches Galveston Bay and the Gulf of America by way of Quil Miller Creek, Village Creek, the West Fork Trinity and the Trinity: about 510 river miles.
Lake on the way: Woodlands Golf Course Lake.
270 miles of the trip are on the Trinity.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Briaroaks; river miles along the main stem, rounded.
Briaroaks has a humid subtropical climate. Summer afternoons average 95° in July; winter nights fall to about 33° in January. About 36 inches of rain fall in a normal year.
On November 14 Briaroaks normally reaches 67° and falls to 44°. The record high is 89°, in 1989; the record low 23°, in 2019. The most rain on this date, 0.70 in, fell in 1993.
Normals 1991–2020 and records since 1985 at Burleson, 2 miles west. NOAA, through RCC-ACIS.
