A ventifact (also wind-faceted stone, windkanter [1]) is a rock that has been abraded, pitted, etched, grooved, or polished by wind-driven sand or ice crystals. [2] The word “Ventifact” is derived from the Latin word “Ventus” meaning ‘ wind ’.
A dreikanter is a type of ventifact that typically forms in desert or periglacial environments due to the abrasive action of blowing sand. [1] [2] Dreikanters exhibit a characteristic pyramidal shape with three wind-abraded facets. The word Dreikanter is German for "three-edged."

Ventifact at Ventifact Ridge. Ventifact Ridge is a part of a basaltic lava flow. The rocks on its exposed and barren ridge are famous for being shaped by wind erosion and are called ventifacts. Sharp edges of ventifacts called Kanters are formed when two or more facets (planar surfaces) intersect. Open grooves in the ventifacts are called flutes.
Hematite-rich BIF ventifact from Wyoming, USA. (~5.9 cm across at its widest) Ventifacts are lustrous, polished rocks with subplanar to curved facets. They form by natural abrasion and polish by winds that carry sand grains. Ventifacts are naturally sand-blasted rocks. The rock shown above is a BIF - a banded iron formation.
