Anthony Cook (July 2010)Description:
Highly structured, almost dendritic filament-like debris flow down hill and no obvious signs of boulders at their ends.Interest:
It is always difficult to estimate the age of surfaces on slopes because crater impacts are not preserved well. However slopes are precisely where we would expect to see recent change because material has a greater tendency to fall down hill than on gentler slopes. What we are interested in here is not isolated boulder tracks (it is difficult to tell if these are old or young), but more detailed structures that presumably would be wiped out or disturbed if they had been there a long while. So any complex patterns, such as these, are worth looking out for, especially on steep slopes of other craters.

If you find what you think are filament-like threads, similar to the ones above, please post them in this thread.
Don't forget a picture, the strip reference (LROC / NAC reference) and the approximate latitude and longitude.
