Ranger’s center stands about 1,430 ft above sea level. Within three miles the land runs from 1,380 ft to 1,580 ft, a difference of 200 ft: rolling country. The highest named summit within 15 miles is Blue Hills, about 1,700 ft, 14 miles southeast.
Under the town center the state geologic map shows Ranger Limestone and Placid Creek Shale, undivided (black-shale), from the Carboniferous, 299 to 324 million years old.
The section below crosses 11 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 32×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone, claystone. Age: Early Cretaceous, 100 to 145 million years old. About 6 mi of the line.
Black-shale. Age: Carboniferous, 299 to 324 million years old. About 4 mi of the line.
Sandstone, shale. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Black-shale. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.
Black-shale. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.
Sandstone, limestone. Age: Carboniferous, 299 to 324 million 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. 5 smaller units along the line are not listed.

A raindrop that lands in Ranger reaches the Gulf of America by way of Palo Pinto Creek and the Brazos: about 680 river miles.
Lake on the way: Lake Granbury.
550 miles of the trip are on the Brazos.
