Kachina Chasmata [SEP] located on astronomical body
Kachina Chasmata
The Kachina Chasmata are the longest canyon or system of canyons on the surface of the Uranian moon Ariel. The name comes from a spirit in Hopi mythology. The 622 km long and 50 km wide chasmata arise from a system of normal faults running from the north-west to south-east. The faults bound down-dropped crustal blocks forming structures called graben. The canyons cut the cratered terrain, which means that they were formed at a relatively late stage of the moon's evolution, when
Uranus, scientists using advanced processing methods were able to detect some details in the dark hemisphere. These analyses revealed a continuation of the Kachina Chasmata into the dark hemisphere, possibly as far as to the opposite limb. As the total length of the feature appears to be 1800–2200 km, it may be comparable to Ithaca Chasma on Tethys.
