Crater Chain Boulevard
This is a very busy section for crater chains/secondary impacts near the Lunar North Pole at 72.51 N, 121.37 W
The impact formation at top right is especially interesting:
It is somewhat of a mystery to me on how it formed. You can see what appears to be an ejecta blanket that perhaps moved in a W-E direction giving the surface a sculpted and scraped appearance. That would be fine except for the line of craters that have made a chain of impacts on the left edge of this formation that would seem to have come in from a N-S or S-N direction. Notice there is no surface ejecta sculpting to the left of this chain.
What are your thoughts?

anyone find any possible cave openings in some of the craters ?
