The Annetta North 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.
88° on Nov. 16, 2025, the hottest reading for this week of the year since 1902. Next is 87° in 1938.
Annetta North’s center stands about 860 ft above sea level. Within three miles the land runs from 810 ft to 1,050 ft, a difference of 240 ft: rolling country. The highest named summit within 15 miles is Tater Nob, about 1,170 ft, 6 miles southwest.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 35×. 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. Age: Early Cretaceous, 100 to 145 million years old. About 8 mi of the line.
Limestone. Age: Early Cretaceous, 100 to 113 million years old. About 6 mi of the line.
Limestone, shale. Age: Early Cretaceous, 100 to 145 million years old. About 4 mi of the line.
Limestone, marlstone. Age: Early Cretaceous, 100 to 145 million years old. About 3 mi of the line.
Clay. Age: Early Cretaceous, 100 to 145 million years old. About 2 mi of the line.
Limestone. Age: Early Cretaceous, 100 to 145 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. 2 smaller units along the line are not listed.

A raindrop that lands in Annetta North reaches Galveston Bay and the Gulf of America by way of the Clear Fork Trinity, the West Fork Trinity and the Trinity: about 540 river miles.
Lakes on the way: Woodlands Golf Course Lake and Benbrook Lake.
270 miles of the trip are on the Trinity.
