The Lone Oak plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
19° on Nov. 13, 2019, the coldest reading for this week of the year since 1975. Next is 21° in 1997.
Lone Oak’s center stands about 560 ft above sea level. Within three miles the land runs from 450 ft to 580 ft, a difference of 130 ft: gently rolling country.
Under the town center the state geologic map shows Kincaid Formation (clay, sand), from the Paleocene, 56 to 66 million years old.
The section below crosses 2 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 18 mi of the line.
Clay. Age: Late Cretaceous, 66 to 72 million years old. About 0.7 mi of the line.

A raindrop that lands in Lone Oak reaches the Gulf of America by way of Bull 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 Lone Oak; river miles along the main stem, rounded.
Lone Oak 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 Lone Oak 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.
