Description
Subvertical ramps are characterized by a single surface opening and an inclined (75-20 degrees) tunnel. The tunnel may have an elliptical to circular cross section and is straight to sinuous. Sections of the tunnel may be enlarged into chambers at one or more point along its length. Subvertical ramps are frequently the first type of burrow to be produced by the organism and are sometimes abandoned days after being produced. They are used as temporary shelters or permanent dwellings. Subvertical ramps may be modified into J-, U-, or Y-shaped burrows.
