TLP Project - The Landslides of Birt / Gullies
« on: July 16, 2010, 06:50:29 pm »
Background: See this thread for background on this project: Moon Zoo Challenge

Location: Site: Birt crater (~8.5W, ~22.4S).

Images: M114010282RE

Discovery: 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.

See this Image of the Week post for further information: http://forum.moonzoo.org/index.php?topic=414.0

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.
Good luck!  :)

I've found similar "thread-like" patterns on the edge of Proclus crater.



Latitude=16 Longitude=46
LROC strip = M113649971RC

I'll post more from this area later.

These are really stunning images of debris flows. Thanks for providing people with a guide to these spectacular features. We would ask you to please identify these as 'other' in the Moon Zoo classifying task... thanks! Katie

Another two from Proclus crater:



This looks like a landslide:
