Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>There is a picture here http://ciclops.org/view.php?id=5156&js=1 about halfway down the page that shows the context image for the close-ups.&nbsp; They are just tiny portions of the tiger stripes, but yes Sulcus (Sulci ?) are the stripes.&nbsp; I have been looking forward to searching for hot spots in Damascus Sulcus since that picture was supposed to be the best one to see the bottom of the fracture.&nbsp; The captions for the "Skeet Shoot" images says they are upside-down from the track preview images so I rotated #7&nbsp; ,brightened it up and had a look.It kinds of looks like the frozen waterfalls from my ice climbing days overlaying the top and especially the bottom edge of the rift.&nbsp; I think this spot is in about the same place as the one with the yellow circle.How about it?&nbsp; Did I find one of the hot spots?&nbsp; It shows real well in the .tiff from CICLOPS but the way pluck hacks images I just uploaded a little .jpg.&nbsp; Edit: spelled CICLOPS Cyclops <br />Posted by bobw</DIV><br /><br />I had a go on the same image.

Emily Lakdawalla has arranged the best organized presentation of the flyby images here.&nbsp; <br /><br />http://planetary.org/data/cassini/enceladus_080_raw.html<br /><br />She wrote that one set is missing.&nbsp; Has anybody seen raw images for Frame 3 at the planetary image database? <div class="Discussion_UserSignature"> </div>

<p>Another update is&nbsp;now available on the NASA blog: the Infrared Spectrometer (CIRS) nailed the Damascus Sulcus as planned,&nbsp;which is an active&nbsp;fracture and the one that I cropped earlier (see here). Very interesting. <img src="http://sitelife.space.com/ver1.0/content/scripts/tinymce/plugins/emotions/images/smiley-laughing.gif" border="0" alt="Laughing" title="Laughing" /></p> <div class="Discussion_UserSignature"> </div>

Unless I'm mistaken, you can put the pictures in perspective by comparing them side to side with anything on (e.g.) Google maps/Earth. &nbsp;The google maps pictures are roughly at 10m/px scale when the bottom scale reads '1km', etc. <div class="Discussion_UserSignature"> </div>
