The Teague 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.
Teague’s center stands about 530 ft above sea level. Within three miles the land runs from 420 ft to 550 ft, a difference of 130 ft: gently rolling country.
Under the town center the state geologic map shows Calvert Bluff Formation (claystone), from the Late Paleocene to Early Eocene, 48 to 59 million years old.
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.
Claystone. Age: Late Paleocene to Early Eocene, 48 to 59 million years old. About 14 mi of the line.
Claystone. Age: Paleocene, 56 to 66 million years old. About 7 mi of the line.
Sand. Age: Paleocene, 56 to 66 million years old. About 2 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 1 mi of the line.
Clay. Age: Paleocene, 56 to 66 million years old. About 0.8 mi of the line.

A raindrop that lands in Teague reaches the Gulf of America by way of White Rock Creek, Holman Creek, Big Creek, the Navasota and the Brazos: about 380 river miles.
Lake on the way: Lake Limestone.
230 miles of the trip are on the Brazos.
