QUOTE (tty @ Mar 19 2007, 06:40 PM)  They are actual holes in the roof of the tube, I know - the still I did is sort of an X-Section along the tube. Doug |

Pulled out what I can find from the HRSC images....one could, if feeling hatefull towards ones ISP - get some of the stereo pairs and have a go, but I don't think you would learn much.

I guess this is a pretty stupid question, but why are they so round? I would expect a tube collapse to be sinuous, or at least oval.

Perhaps impactors punched holes in the roof? Even small secondaries would probably have power enough to do that.

They look transposed vs the original images, but on another note, is there any value in stacking them? There are three images of Dena and two of the others to work with.

This would be how the collapse starts. For the final stage see the natural bridge in Tartarus Colles: http://www3.telus.net/paulanderson/bridge_PSP0014202045.jpg Note the roughly semicircular edges either side of the bridge. |

Is there any radar coverage of any of these areas or would this become an interesting candidate? Or is the radar sensitive enough at 100m depth?
Seems from the discussions here that a lava tube type collapse is most likely so perhaps there is no need for radar coverage. still just wondering. -------------------- Turn the middle side topwise....TOPWISE!!
