natural surface
Unpaved ground cover
A natural surface is ground that remains in its original state—dirt, grass, gravel, or packed earth rather than asphalt or concrete.
The term appears most often in contexts involving roads, trails, and athletic facilities: The park maintains ten miles of natural surface trails.
A natural surface road is unpaved, subject to weather conditions that paved roads resist.
