Lethe Vallis (Mars)

Named after the River in Katmai National Monument, Alaska, USA.

Lethe Vallis originates at the SE margin of the West Elysium Basin. It was probably formed in just days or weeks and had a discharge about like the Mississippi. Some have suggested it was formed from lava flows, but lava would not be able to flow over such a low gradient for so long a distance. (wikipedia entry)

A vallis is a valley. On Mars large valles are named after words for Mars/star in various languages. Small valles are named after classical or modern names of rivers.
