The Glen Rose plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
Glen Rose’s center stands about 630 ft above sea level. Within three miles the land runs from 590 ft to 890 ft, a difference of 300 ft: rolling country. The highest named summit within 15 miles is Lone Mountain, about 1,340 ft, 14 miles west-southwest.
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 29×. 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, shale. Age: Early Cretaceous, 100 to 145 million years old. About 6 mi of the line.
Sandstone. Age: Early Cretaceous, 100 to 145 million years old. About 5 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 4 mi of the line.
Limestone, marlstone. Age: Early Cretaceous, 100 to 145 million years old. About 4 mi of the line.
Claystone. Age: Early Cretaceous, 100 to 145 million years old. About 3 mi of the line.
Coarse-detrital, fine-detrital. Age: Quaternary, less than 2.6 million years old. About 1 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 Glen Rose reaches the Gulf of America by way of Wheeler Branch, the Paluxy and the Brazos: about 510 river miles.
