“Distal end of Lethe Vallis”, around 4N 156E on the Elysium Planitia.
Lethe Vallis is named for the River Lethe, which runs through the Katmai National Park in Alaska. The River Lethe, in turn, is named after Lethe (Λήθη), the river of forgetfulness that ran through Hades. The dead were required to drink from Lethe, erasing the memory of their former life, before being reincarnated.
