After some investigation, I did a small movie around the "geiser" image. It look like something is going on in this area. Unfortunately, we cannot see further down the image. For this movie I used those images: N00030070.jpg N00030071.jpg N00030072.jpg
If you look straight up the images, you see a wide valley with semi-cicular features which could be coming from this outpouring of "stuff" from a sort of moving "hot spot" under the crust or a moving crust. Does this make sense? Thanks

Neat, But I'm not sure where to look?
Is there any way to stable the image better? |

There's definitely something there that is blurrier than the rest of the image - that puff or whatever stays blurry even as the rest of the image sharpens. Unless it's a reflection in the lens, it has to be a cloud of some sort.

Simply looks like a smooth crater to me.

Not everything that looks blurry is a cloud. I've seen quite a few MOC images where you'd swear the image was out of focus, but then you notice some feature, maybe a small, fresh impact crater, and realize that the image is in fact quite crisply focused and the landscape itself is blurry.
The 14 March 2005 MOC image of the day provides a reasonably good example. The dunes themselves are fuzzy, but if you look closely at the space between the dunes, you'll notice there's quite a lot of fine detail. |

Here is a better view of the blurred area, near the center of the image
http://saturn.jpl.nasa.gov/multimedia/imag...eiImageID=34966 The crater is on top of the fissure, therefore younger, the blurred area is its ejecta blanket. |

that would make sense, since all the craters seems to be blurry compared to their surroundings

or, the fracture propagated through the ejecta blanket of that crater and due to the weak regolith surrounding the crater, mass wasting is enhanced in that area of the fracture.
