Lake bed?

  • dave_the_planetbuilder by dave_the_planetbuilder

    Could this be a lake bed? Black crescent shaped patch in river system towards upper left, lower dark area. appears to follow general course of drainage.

    Hi Dave,

    There are many places in polar areas that look like lake beds especially because polar areas tend to have a lot of free moving dust and sand. This allows dunes and ripple to form. The really hard part is to prove that it is lake bed, and for that you'd need at least fitting composition. You can get that from CRISM (spectrometer on board of MRO) for example.

    Thank you for helping!
