Dogon Ladder

The Dogon people of Mali create ladders by carving wedges into tree trunks that fork at the top.  The notches serve as footholds, while the fork at the top stabilizes the ladder.  The Dogon use ladders to climb to their traditional cliff dwellings and to raised granaries.

Another Dogon object that has been featured for Artifact of the Month is a Kanaga mask.
