Old River-Winfree’s center stands about 40 ft above sea level. Within three miles the land runs from 0 ft to 70 ft, a difference of 70 ft: gently rolling country.
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 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.
Sand. Age: Pleistocene, less than 2.6 million years old. About 11 mi of the line.
Clay, silt. Age: Pleistocene, less than 2.6 million years old. About 6 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 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.
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 Old River-Winfree reaches Galveston Bay and the Gulf of America by way of the Old and the Trinity: about 18 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Old River-Winfree; river miles along the main stem, rounded.
