While not a visual observer, I thought I would try posting a bit more in the Lunar Observing forum because of my focus on imaging the moon.

 

Earlier this year I caught some good imaging and lighting around Mare Humorum.  I find the rilles of Rimae Hippalus one of my favorite features in the area and find their concentric nature intriguing.  The three main rilles are fairly easy to observe, but the fourth rille is more difficult to observe but the lighting in the attached image show this fourth rille fairly well.  I do presume they were created by the impact that made Mare Humorum which is lava filled.

Nice shot.

 

The interesting feature that catches your eye is the isolated mountain landslide that rolled into the graben.

Thanks for the compliment Frank.  With regard to that particular feature, unfortunately it doesn't appear to be a rockslide.  Looking closely at LRO imagery doesn't show any slide in that area - it appears the mountain feature existed prior to the formation of the rille (see image below from the LRO).  Very cool region nonetheless when you think about it deforming a mountain like that.

If you back out just a bit on the LRO photo I think you will see it better.

It appears to be material sliding into the graben.

I think Charles A. Wood commented on this feature in Lunar Photo of the Day

years ago.
