Kachina Chasmata (Ariel)

Pueblo (USA) good spirits who bring rain or other blessings.

Kachina Chasmata is the longest canyon or system of canyons 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.

A chasma is a deep, elongated, steep-sided depression. On Ariel they are named after light spirits (individual and class).
