earth pillar

earth pillar
   A tall, conical column of unconsolidated to semi-consolidated earth materials (e.g., clay till, or landslide debris) produced by differential erosion and usually capped by a flat, hard rock fragment that shields the underlying, softer material from erosion. It can measure up to 6-20 m in height, and its diameter is a function of the width of the protective boulder.
   Compare: hoodoo.
