How about once liquid?

REB — 5/29/2007 12:57:31 PM (archived)

Could it be some very dark volcanic rock that filled a crater? Would something as dark as asphalt not show any detail if it was fairly smooth?

        I can not find an MOC image for those exact coordinates. - REB - 5/31/2007 6:46:36 PM
        
        I am searching through the MOC files for it. I found another one very close to it. - REB - 5/31/2007 5:57:40 PM
        
        And notice that dark layering in those collapsed lava tubes. - REB - 5/31/2007 6:06:37 PM

        Why not a MER? - Lee - 5/27/2007 8:21:39 PM
        
        MERs should be standard equipment. - Lee - 5/27/2007 10:47:30 PM
        
        Where would it get its energy if the Sun doesn't shine in the hole? (n/t) - Raoul - 5/29/2007 7:32:26 AM
        
        The MER wouldn't go into the hole. - Lee - 5/29/2007 11:21:23 AM
        
        MER would make a good platform - Fox - 5/30/2007 4:00:19 AM
