I think there are some interesting comparisons to be made between the cliff edge morphology we are seeing at Victoria and that revealed along the edges of Cerberus Fossae in the latest HIRISE images (See lyford's post 162 in 'First Pictures' thread for the zoomable version). Scalloping, slumping, fallen boulders, 'soup dragons', etc. The scale is about comparable too. I'm sure you image experts can find some quite good matches.
