Ventifacts in rocks of Mars
This image shows pits and holes (ventifacts) in a small rock found by the Mars Pathfinder Rover. These ventifacts are artifacts of weathering on Mars and were created by wind erosion. The Souffle rock also reveals a very pitted surface.
Analysis of this particular rock shows it to be a conglomerate. Conglomerates are sedimentary rocks, formed under conditions of turbulent water. Other conglomerates found at the landing site include the Shark and Half Dome.
