Description
Vertical shafts are characterized by a single surface opening with a vertically oriented (~90 degree) tunnel. The shaft has an elliptical to circular cross section and is generally straight. In many cases vertical shafts include a widened portion, or chamber, near their base in which the animal resides. Vertical shafts are frequently the first type of burrow produced and are sometimes abandoned quickly. They are utilized as temporary shelters to permanent dwellings.
