OK I've been poring over these horizon images along with my retrojected orbital HRSC image and other bit and pieces from this thread + Google Mars for ages! I am now pretty confident that I have everything identified correctly (or pretty close).

That is a fantastic piece of work James. I did wonder about that part of the skyline beyond Endeavour too. Are we sure it's not part of the Iazu apron?
PS - I wish they'd pan around to the north rim again. |

Would projected CTX images be of use? The PDS released images are uncalibrated and unprojected, but I've got the process sorted in ISIS3, it's not too bad actualy, so if someone gives me the ob-ID, I'll get them map projected.

That's a brilliant piece of detective work, James. Really brings the whole scene to life.
I wish we had some names - even just working names - for those distant hills and peaks. Maps are so much better with names. Soon tho, I'm sure. -------------------- |

ngunn,
I don't think the distant horizon can be part of Iazu, it just doesn't stretch that far east. Also, it looks more 'hazy' than the rest of Iazu. Looking at Google Mars it does suggest that we should have an horizon about 10km (ish) beyond Endeavour in that direction. Doug, I'd love to have a CTX base map of the area. Not sure how much time I'll have to do any further analysis, but here are some ID's of CTX images that would cover all of Endeavour and Iazu. P13_006135_1789_XN_01S005W P15_006847_1770_XN_03S005W P17_007849_1793_XN_00S005W Stu, Rui has named everything around here hasn't he? James -------------------- |

Anything Rui has not named, will just call it Ultreya A through Z.
I've got those three CTX images downloading (140-250 meg each - and I generate about 4 times that in the CTX processing pipeline) - I'll squirt them out tomorrow...and SEE how hard it is to mosaic them within ISIS...but I wont spend to much time on that. I'll zip up PNGs or something and send you a link. |

For the P13 ob - ISIS is happy. For the other two, I don't think the kernels have hit the ISIS Rsync server, so I can't project them reliably. I'm going to fudge it assuming nadir-pointing.

Had you tried searching for their correlative HiRISE's? The pointing would be the same.

It would error the same way- tge kernels are external to the images, and HiRISE data would simply be looking for the same missing data. The kernels are quite laggy getting into ISIS, way behind the imaging data.

There may be others that cover the same area, I just grabbed a few ID's off of Google Mars.
It would be good to have as accurate a map as possible to help with alignment of horizon features - fudging it may just confuse me more than I already am! -------------------- |

Well - anything starting 13 or less is great. I'm not sure they started imaging that way much before it was decided to head there thigh. CRX is 30km wide though - so we might be in luck.

There may be others that cover the same area, I just grabbed a few ID's off of Google Mars. I'm used to search at this site: Mars Global Data. Start with the "webmap" option, zoom to the area of interest, click on the arrow button (select) and then on the map again. |

WARNING! If you've never used Mars Global Data before, be very careful. It's dangerous. VERY dangerous. It's the Mars website equivalent of a packet of Pringles or a box of Maltesers - once you start, you can't stop. Oh yes, you go on there thinking "I can handle it, I'll just have a quick look", then you start clicking... and clicking... You tell yourself "Just one more"... click... "Ok, just ONE more..." click... and before you know it it's dark outside, the rest of the family are in bed, and there's a cold cup of coffee on the desk beside you...

Fantastic work James! I can't believe we have come this far, able to see the hills REALLY unfolding before our eyes...
About the names...we all know they've been chosen for quite some time don't we? Ah! -------------------- "Ride, boldly ride," The shade replied, "If you seek for Eldorado!"

I wasn't discounting your names Rui I meant more 'official' names so we can all follow the journey. Your names are great. You're going to need some more tho, looks like lots of smaller peaks on top of the main hills. Better start researching if any of those sailors had pet dogs or cats...
