One of my favorite oblique impact craters - well, really two of them -

is this pair, posted at "Files/Other/Oblique_Impacts_Mars.jpg"

Of course, it'd be a tad difficult to image from here!

What's interesting is that both craters are double, both have

fluidized ejecta blankets to either side - making them look like

"bugs".  And they are along a line, suggesting that they from from the

same parent body that broke apart as it approached Mars at a very

shallow angle.

Hi Duane -

I think the jury is still out on the formation of Schiller (but  

leaning towards an oblique impact):

Looking straight down via Lunar Orbiter images (or in earth based  

images taken at a low sun angle) that bizarre caldera topped mountain  

is clearly seen as two separate features - a long hill with a crater  

on the floor of Schiller just behind.

Thanks,

Alan

Hi Alan,

Nice shot. It makes me eager for ver. 4 but then again I know this  

image is from you and

part of me knows you're taking it beyond my capability :)

I never looked at Schiller closely before, but it appears to be two  

craters joined (and

flooded) together creating the potato shape, doesn't it? Maybe  

that's already known, but

then again self discovery is good too.

Thanks for sharing and keep'em coming.

Duane
