Sinton’s center stands about 50 ft above sea level. Within three miles the land runs from 30 ft to 70 ft, a difference of 40 ft: nearly flat ground.
Under the town center the state geologic map shows Lissie Formation (silt, sand, clay), from the Pleistocene, less than 2.6 million years old.
The section below crosses 3 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, silt. Age: Pleistocene, less than 2.6 million years old. About 14 mi of the line.
Sand. Age: Pleistocene, less than 2.6 million years old. About 6 mi of the line.
Silt, sand, clay. Age: Pleistocene, less than 2.6 million years old. About 4 mi of the line.

A raindrop that lands in Sinton reaches the Gulf of America by way of Chiltipin Creek and the Aransas: about 30 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Sinton; river miles along the main stem, rounded.
