Pendleton’s center stands about 750 ft above sea level. Within three miles the land runs from 650 ft to 820 ft, a difference of 170 ft: gently rolling country.
Under the town center the state geologic map shows Eagle Ford Formation and Woodbine Formations, undivided (black-shale, sand), from the Late Cretaceous, 66 to 100 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 56×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Black-shale, sand. Age: Late Cretaceous, 66 to 100 million years old. About 14 mi of the line.
Marlstone, chalk. Age: Late Cretaceous, 66 to 100 million years old. About 8 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 3 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 Pendleton reaches the Gulf of America by way of Kings Branch, Big Elm Creek, the Little River and the Brazos: about 400 river miles.
320 miles of the trip are on the Brazos.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Pendleton; river miles along the main stem, rounded.
