Inverted Channels North of Juventae Chasma

This image shows raised ridges on a plain to the north of Juventae Chasma, a canyon
that is part of the Valles Marineris system. Several examples of raised features have
been identi!ed on the plains nearby; they have been explained as former stream
channels that are now preserved in inverted relief. On Earth, inverted relief occurs
when former depressions become elevated because materials that !ll the depressions
are more resistant to erosion than the surrounding terrain.
