Bright Deposits and Channels in Thaumasia Planum
This area is dominated by bright exposures as revealed by CaSSIS instrument data as well as Context Camera images. The Thaumasia plateau is south of the Valles Marineris canyon system and consists of high lava plains partly surrounded by rugged highlands, mostly of Noachian and Hesperian age. The name comes from Thaumas, Greek god of the clouds and celestial apparitions.
