Valles Marineris

Another image from Astronomy Picture of the Day.
Sunday’s picture, this is a composite photo of Mars showing the great rift valley named Valles Marineris which almost bisects the hemisphere shown.
3,000 kilometres long, 600 across and up to 8 deep, Valles Marineris could swallow the Grand Canyon many times over.
Mind-boggling.
