QUOTE (rlorenz @ Dec 22 2007, 09:06 AM)  Caitlin Griffith made first spectroscopic detection of clouds on Titan with the 1995 outburst. But an HST observation very close to that time (just a couple of weeks different, so maybethe same outburst) shows cloud system at 40 degrees NORTH - nowhere near the south pole(there is a map showing this cloud in Lifting Titan's Veil..) rlorenz.. Thanks so much for the response.. I'll have to go back through the literature..... I had the impression the larger outbursts had been determined to be similar to the south pole clouds seen by CASSINI in 2004. If the south pole clouds were methane cumulus clouds, wonder if the downpours made it to the surface? I believe you have written on the physics of this, and that the air would become saturated enough to allow the drops to hit the surface. If that is the case, and these storms were a common summer time feature over the pole, what sort of erosion will we see at the surface? Really wanna see this SAR!!!! Craig |

I don't think you are imagining ALL of those apparent rivers. The thicker one flow south looks plenty real.

Agreed...if I didn't know better, it almost looks like an estuary! Welcome, Gladstoner.

Nice.
And if we got lucky, the swath hit the transition between the fractal lake morphology and the smooth shoreline morphology. I can't wait 'till it gets released! -Mike -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/

I share your eager anticipation, looks like the radar traversed a very interesting region.
Is that part of Mezzoramia at the far end of the swathe? |

What Tha !!!!!!
Titan trumps us again....... but as I noted in post #16, the methane rain on these plains certainly tore up the terrain (erosion from the summer cloud bursts). Craig |

Totally uninformed observers comment...
It looks just like the Severn Estuary - complete with the bow south of Gloucester. http://maps.google.co.uk/?ie=UTF8&ll=5...p;z=11&om=1 |

Some parts of the image look like the formations seen in some of the Salt Marshes in East Anglia.

And check this out!
http://photojournal.jpl.nasa.gov/catalog/PIA10219 Look how the (wet muds?) display channels that look like sapping. And as you go further south in the image, the sapped channels get wider and wider, until they turn into narrowing ridges (wider valleys thus narrower ridges). Until only the thin ridges are left. Just like a really cool Escher drawing. Wow! -Mike -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/

But you still missed the two coolest lakes of all down there But you did catch a few of our lakes. -------------------- &@^^!% Jim! I'm a geologist, not a physicist!
