Kachina Chasma (or Kachina Chasmata) is the longest canyon on the surface of the Uranian moon Ariel. Its name comes from a spirit in Hopi mythology. The 622 km long and 50 km wide chasmata is a system of normal faults running from the north-west to south-east. The faults bound down-dropped crustal blocks forming structures called graben.
