Do a forum search on erosion / weathering .

Yup , they degrade over time . I am assuming , they want boulders with boulder tracks so they can differentiate from weathering . Tracks give them some kind of timeline as they don't last forever .  And the exploding part (as opposed to just fell of ) tells them there may be another process at work here .

You may want to try it a little different Jules . Boulder tracks are hard to spot above 1/mp . However the boulders themselves are pretty bright and gnarly at 4 to 8 mp . If you take the example pic on act and zoom out to your maximum ( eye comfort level ) That you can make out the boulder , you can see the difference in boulders vs crumbly boulders . I've also noticed sussing out downhill from even bigger cliffs can produce pleasing  results .
So I would add ,
1. Search ( at max comfortable zoom level ) for boulder producing areas .
2. Zoom in a bit and look for Fuzzy boulders ( being crumbly they wont be as sharp as a whole rock )
3. Zoom in and look for tracks .

Impact areas can be fun too , if they strike an area where they can dislodge material instead of ejecting it .
Looking in the hills finds some prospects also .

All that being said , I have yet to find a good example myself as all of them seem to have just fallen apart and not exploded .

Even went to the poles to see if something fell out of the frost zone/perpetual shadows , and popped .


This is not an easy task no matter how you go about it , but I think you'll wind up with some intensive boulder expertise by the time it's done !

Good idea . I think I saw more weathered boulders in Schiller , when I breezed through . Then I went sussing about to narrow down some search parameters . Still working on that , but seems to be more prospects in an about older craters .

Could you have found a harder one to suss out ? 



This is your crater.



This is your crater on Act . In red is a good marking crater  for orientation , the blue is your linear features .
I was thinking secondary craters due to the crater chain running up the left side of the pic . However I went in the wrong direction initially . This crater chain heads to the Northwest quite away but I'm not posting those because I think it's the wrong direction .



32/Mp showing the marking crater .



Here the red is the somewhere in the vicinity of the marker .



And finally back tracked to where you ask , where else , Aristrchus ! Just guessing  .

Next  .

There is abit more if one would follow the act link up or down slope . I think this is something a smart person should chime in about Ireneant .

Seems it may be a good example of lunar viscosity related to impact ejecta , maybe related to proximity of impacted material vs the actual impact , Time in the entrained atmosphere ,and maybe composition . Just geussing  .

It would be the bubbely looking stuff taking up most of the left side of the pic . Keyword " INA LIKE "

Now thats wickedly cool as it is on the north slope of Aristarchus !

A nice little duet ! Appears they came in < 90 deg from one and other with the fresher White ejecta slightly overlaying the Darker excavated material from the crater on the left .
