About this image
Hebes Chasma is the northernmost canyon of the vast Valles Marineris system. It contains a 7-km thick pile of sediments known as an interior layered deposit (ILD), which is common to many of the Valles Marineris canyons. This ILD shows fine layers, deep spur-and-gulley erosion features, and an unusual texture on the plateau surface that may be due to dunes.
