South Houston’s center stands about 30 ft above sea level. Within three miles the land runs from 20 ft to 50 ft, a difference of 30 ft: nearly flat ground.
Under the town center the state geologic map shows Beaumont Formation, areas predominantly clay (clay, silt), from the Pleistocene, less than 2.6 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, silt. Age: Pleistocene, less than 2.6 million years old. About 13 mi of the line.
Sand. Age: Pleistocene, less than 2.6 million years old. About 11 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in South Houston reaches Galveston Bay and the Gulf of America by way of Berry Bayou, Sims Bayou and Buffalo Bayou: about 18 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of South Houston; river miles along the main stem, rounded.
