What is the name of a cul de sac with no pavement

An unpaved cul-de-sac.


A roadway cul-de-sac ("bottom of the sack" a French/Latin anatomical term) is a kind of dead end street that is circular at the end allowing a vehicle more ability to turn around, and therefore resembles the bulge at the bottom of an anatomical sac. Large cul-de-sacs can be driven around without having to do a 3-point turn, and some even have a central circular feature called an "island" that can include plantings.
