Galilaei (Martian crater)

Galilaei is located north of Hydaspis Chaos in the area east of Tiu Valles and west of Ares Vallis.

[2] Galilaei is one of the numerous large craters that formed during the Noachian Period, which ended around 3.7 billion years ago.

[3] The crater floor was modified by superficial geologic processes through Late Hesperian time, as mapped by Tanaka, K.L.

[citation needed] Tana Vallis is 60 km (37 miles) long and begins at the southwest rim of Galilaei Crater.

The impact-altered material in the rim of Galilaei Crater would have been more easily eroded than intact basalts, and therefore the breach channel would have formed relatively fast.
