3D visualization of the buried Marte Vallis channels beneath the martian surface. Marte Vallis consists of multiple perched channels formed around streamlined islands. These channels feed a deeper and wider main channel. Please note the surface has been elevated, and scaled by a factor of 1/100 for clarity. The color scale represents the elevation of the buried channels relative to a martian datum (Note: the reason the values are negative is because the elevation of the surface of Mars in this region is also a negative – below average global elevation).
