Annetta South’s center stands about 850 ft above sea level. Within three miles the land runs from 780 ft to 1,050 ft, a difference of 270 ft: rolling country. The highest named summit within 15 miles is Tater Nob, about 1,170 ft, 8 miles west-southwest.
The section below crosses 9 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 32×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone. Age: Early Cretaceous, 100 to 113 million years old. About 7 mi of the line.
Limestone. Age: Early Cretaceous, 100 to 145 million years old. About 4 mi of the line.
Clay. Age: Early Cretaceous, 100 to 145 million years old. About 4 mi of the line.
Sandstone. Age: Early Cretaceous, 100 to 145 million years old. About 3 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 2 mi of the line.
Limestone, shale. 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. 3 smaller units along the line are not listed.

A raindrop that lands in Annetta South reaches Galveston Bay and the Gulf of America by way of the Clear Fork Trinity, the West Fork Trinity and the Trinity: about 530 river miles.
Lakes on the way: Woodlands Golf Course Lake and Benbrook 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 Annetta South; river miles along the main stem, rounded.
Annetta South has a humid subtropical climate. Summer afternoons average 95° in July; winter nights fall to about 32° in January. About 35 inches of rain fall in a normal year.
On November 14 Annetta South normally reaches 67° and falls to 43°. The record high is 85°, in 1989; the record low 18°, in 2018. The most rain on this date, 1.46 in, fell in 1923.
