Busy preparing a new Outreach talk here, and have been trying to find some images to illustrate the "power" of HiRISE for a non-technical audience. Playing about with - sorry, carefully looking at the images on - the addictive Mars Global Data site I found a cute landslide on Xanthe Terra that does the trick nicely. Using the IAS Viewer you can zoom in on the boulders carried down the slope by the landslide and even see cracks and splits in them... unbelievable...!
Anyone else got any fave examples? -------------------- |

The dust avalanche is now featured at the HiRISE website:
http://hirise.lpl.arizona.edu/ESP_017229_2110 The location is in the Olympus Mons aureole (Lycus Sulci) not the slopes of the volcano as the earlier article indicated. This is an area of rough, highly jumbled terrain thought to be formed from huge gravity-slide deposits shed from the lower slopes of Olympus Mons. This region is extremelt dusty and dust streaks are ubiqutous. I couldn't determine the slope of the hillside on which the avalanche occured from MOLA elevation data. The area in the portion of the CTX image shown in the article is very small (only about 2 X 2 km) and below the useful resolution of the gridded MOLA dataset from the JMars program. Maybe someone knows a more sophisticated way to determine the slope. In any case I would guess that 30 degrees or more of slope is certainly possible. Tom |
