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? -------------------- |

It actually helps - as is often the case with HiRISE images, I think - if you look at the black and white version first. Then it is clear that the boulders are "filling in the gaps" between the dunes...
(very cool dust ripple filled crater between the dunes there, don't you think?) The bright "stripe" along the top of the dunes appears to be the dunes' actual peak..? -------------------- |

The bright "stripe" along the top of the dunes appears to be the dunes' actual peak..? The orange stripe in the color image is actually in the slope of the dune face. It's probably just a different grain size than the surrounding material, as that's typically what HiRISE colors indicate. The dune crest is the smooth-looking dark portion in the grayscale image. -------------------- Twitter: @tanyaofmars
