Any ideas what this is ?

[paul mc c]

I was out this evening taking a few shots of the moon,and when scanning the surface i noticed this dark feature that i dont really know what it is,if it is a shadow it seems to be the opposite way fron the other shadows,if you know what i mean...seeing was terrible so the shots are,nt the best...any ideas ?

It is a shadow cast by a raised ‘hill’ (which seems to be called Promontorium Laplace) rather than within a crater, that’s why it looks different. It shows up in various maps I’ve checked.

Yes,that would be it,it just really stood out but that would make sence probably with a fairly sharp incline.

And yet another view of it.

Those hills are quite prominent, I caught shadows off them last night too. Excuse the double image effect, I had problems stacking.

Some awesome forensic analysis going on here, i can here the theme for CSI playing in my head.

Funny

I started off thinking I might need some help with where it actually was, but soon found it on a map.

It gives some interesting shadows depending upon its phase, and goes bright at full phase and into last quarter, with the shadow on the other side obviously.

I think what causes the apparent odd angle of the shadow maybe a curved terraced feature.

These are higher resolution versions of one of the images Stu posted, from the LRO quickmap site.

The curved section would cast shadows for a prolonged period as the sun moved around it and the terrace could have something to do with the apparent break in the shadow.

And just out of interest, apropos of nothing at all, but to remind you what a great resource the LRO imagery is, here's one as close as you can get to the top of the ridge showing what appears to be a rubble field. 

What a great time to be alive!!

Crazy hi res! I use a phone app to access the maps but obviously at far lower res than is available. Must have a look on the website.

This should take you straight to our ROI, with a little topographical info for good measure

One more for good measure before I turn in. Quickmaps has layers to show different imagery and this is a layer showing the area when it's on/near the terminator. It's a little earlier than tonights views hence the elongated shadow. I've also turned on the contour layer to show the elevation.
