Granbury’s center stands about 740 ft above sea level. Within three miles the land runs from 690 ft to 920 ft, a difference of 230 ft: rolling country. The highest named summit within 15 miles is Comanche Peak, about 1,230 ft, 4 miles south.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 43×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone, marlstone. Age: Early Cretaceous, 100 to 145 million years old. About 10 mi of the line.
Sandstone. Age: Early Cretaceous, 100 to 145 million years old. About 7 mi of the line.
Claystone. Age: Early Cretaceous, 100 to 145 million years old. About 2 mi of the line.
Coarse-detrital, fine-detrital. Age: Quaternary, less than 2.6 million years old. About 2 mi of the line.
Limestone. Age: Early Cretaceous, 100 to 145 million years old. About 2 mi of the line.
Limestone, shale. Age: Early Cretaceous, 100 to 145 million years old. About 0.8 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.
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 Granbury reaches the Gulf of America by way of Lake Granbury and the Brazos: about 560 river miles.
Lake on the way: Lake Granbury.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Granbury; river miles along the main stem, rounded.
