Under the town center the state geologic map shows Beaumont Formation, areas predominantly sand, from the Pleistocene, less than 2.6 million years old.
The section below crosses 4 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.

A raindrop that lands in La Marque reaches Galveston Bay and the Gulf of America by way of Marchand Bayou and Highland Bayou: about 7 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of La Marque; river miles along the main stem, rounded.
