Exclamation Mark on Mars

Like this Dragon

I made one of those, it's amazing how it (our brain) works.

And yes, I always rotate the image, as I noticed some years ago that I am easily fooled by the crater/dome problem, so I always check first by other means.

According to HiRise:

Exclamation Mark on Mars
ESP_020794_1860  Science Theme: Landscape Evolution

Turn this image sideways (so North is to the right) and the highstanding landforms look like an exclamation mark.

The origin of these hills may be difficult to understand on such ancient terrain. The straight edges suggest fractures related to faults. Maybe this feature was lifted up by the faulting, maybe the surrounding terrain has been eroded down over billions of years, or both.

@ Zorgon,

So the image I pulled from Google Mars is not a Depression? When I changed Sun positions the shadow followed the line of the Crater all the way around? I may be doing this wrong, so if anyone can tell me how to do this correctly, would be greatly appreciated.



Thanks a head of time.

No.

From what I could see the Sun position on Google Earth is not that good at showing shadows because it uses images that already have shadows, so we get a strange (and ugly) result.

I know Google Moon and Mars are suckee programs for anomaly hunting but maybe if we find this area on Google Mars it will give us elevations "D

Here it is, seen from the north, as it's easier to see that way.

Thanks ArMap!!

I tried to go to Ground view,but for some reason couldn't do it, kind of new to the Google Earth program, so may be getting a lot of question's from me!! LOL

Now, for the topic at hand.

I seen the 'Fault Crack' in the original image and on Google Mars, and with you facing this object from the North it seems it is rather an obscure lift to it, it may be an 'Uplift' from Tectonic shift, not sure anymore, but definitely can see what you are saying here.

"Is there a way you can get all cardinal directions of the image and then we can see each vantage point?" Until I get the Google thing figured out, you could probably do this in a blink of an eye, opposed to me having to do it, pretty much being after I learn how to get the images the way you have captured them.

Looks as if your eye Alt was at -2631 m, so that distance should remain constant.

Thanks again.

I got onto Goggle Mars and ran a lot of elevation lines. It is all over the place and looks nothing like the pretty photo. So I don't know which one to look at. Either way it shows an elevated area. Jagged at best. I still don't have a grasp on the 2 flows and the other trial.
So when in doubt, change the subject.

How you miss this. SSE of !, not very far... 4 sides, hum?

hmm i like to see a HiRISE image of this one

138.5 miles sse

That's why I couldn't find it, I wasn't expecting to be that far.

Apparently, no HiRISE photos from that area.

As for your "flows", I don't see anything strange with them, specially the one I marked as "1", it really looks like something flowed down from that area.

On Google Mars it is only 3 inches away. Real close!

On a planetary scale, 138 miles is close for me, I can even walk it, Ride a bike or take a car.
lol

Portugal is a small country, if I move 138 miles to the east I will end up in Spain.

Not a HiRISE photo but a CTX photo, also from the Mars Reconnaissance Orbiter, showing the "four sided" feature, at 25% zoom.

Very cool ArMap! Maybe I count some more sides also. Maybe this is the famous 4,5 side pyramid from mars!
