Hyginus Crater formations (aka Pork chop hill)

[Geoff]

This thread started out with an image of some formations that looked rather like a couple of pork chops. Other strange formations were found close by so the subject has been changed so we can capture other images from this crater in one place.

Hyginus crater is at the east end of Sinus Medii, and south of Mare Vaporum, the Sea of Vapours. It is a non-impact crater and was probably formed by volcanic action.

Its coordinates are - Longitude: 6.23  Latitude: 7.60

Apollo 19 was due to land in this crater but the mission was cancelled.

Hyginus crater lies along a long rille, called Rima Hyginus. The following image is from the LROC WMS Image site:



An interesting report (PDF format) titled "Magmatic Origin for Rima Hyginus" will be found here: http://www.lpi.usra.edu/meetings/lpsc2010/pdf/1129.pdf


The following image was originally posted as "Pork Chop Hill".

It does!  Yum!    Pork chops and chocolate moon cake

Here's another shot of the same area from further away:

I found an area of the same sort of features myself.

Hi all - please flag types of features such as these as 'other' that way they can go into a general weird stuff classification - thanks Katie

[jules]

Thanks for dropping by Katie - helps us make sure we're classifying as you expect us to!

[Lovethetropics]

So the pork chops are "other".  Check! 

[Thomas J]

Thanks for the input, Katie.

  This good to know. 'other' it is

Edge of a crater maybe?

Edge of a crater maybe?

Oh, what I wouldn't give for context and zoom on this one.

I'm guessing that this isn't a crater, because the slope seems too steep. Also, what's at the bottom of the slope seems too similar to what's at the top. Maybe this is a scarp associated with a linear or sinuos rille (hard to tell from the bit we see here).

In any case, the scalloping at the top of the slope is amazing!

While browsing the LROC site I found that this is in Hyginus Crater.

Sry 4 no coordinates in previous post, I can tell them if someone finds those pics interesting...
Here's something else:

I found that it's actually a slope of a pit - "lake"? - with some channels coming from it, some hundreds kilometers long.
Longitude: 6.38291
Latitude: 7.67317
What's the origin of those channels? Volcanic? Erosion?

The top left portion of the image is inside Hyginus crater. The white area is the edge of the crater.
