Benjamin’s center stands about 1,480 ft above sea level. Within three miles the land runs from 1,410 ft to 1,550 ft, a difference of 140 ft: gently rolling country. The highest named summit within 15 miles is Buzzard Peak, about 1,830 ft, 14 miles west-southwest.
Under the town center the state geologic map shows Clear Fork Group (claystone), from the Permian, 252 to 299 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 55×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Claystone. Age: Permian, 252 to 299 million years old. About 16 mi of the line.
Sandstone-mudstone. Age: Permian, 252 to 299 million years old. About 6 mi of the line.
Shale. Age: Permian, 252 to 299 million years old. About 2 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.3 mi of the line.

A raindrop that lands in Benjamin reaches the Gulf of America by way of Dutchman Creek and the Brazos: about 900 river miles.
Lakes on the way: Possum Kingdom Lake and Lake Granbury.
550 miles of the trip are on the Brazos.
