In response to Daniel's point well taken that ...

"no amount of image enhancement (right) can bring out any further details inside the hole".

I sent the lower res image through a quick routine with input/output Curves and Adjustment layers in Adobe Photoshop. I was surprised to see structure and what seems to be a shelving layer that exists below the rim. The image Daniel produces is higher res and offers greater detail of this shelving (using methods described above).

I'm new to this blog site and as soon I can, I'll post the enhanced view. Or, one can try it with Photoshop, Gimp or Paintshop pro. Even Google Picasa may offer enhancement possibilities.

Neat stuff... the "Spiders in Mars" still have room to maneuver - I'm sure!!!

        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
