On a quick scan I count over 20 craters above 3m diameter inside Victoria, some very subdued and distorted. The drifting dunes are indeed a special case as you say Bob, but the slopes leading from the dune fringe to the base of the cliffs are surely a different "special case". These are talus slopes in motion, in a slow downward creep. The rate of creep (and therefore obliteration of features like little craters) will be greater with increased gradient, therefore greatest at the top of the slope near the cliff base. We know from the boulder track discussions that there is downward motion of erosional products. So I'm not surprised by seeing few extant craters anywhere inside Victoria, although I don't know the maths of cratering rates over time, versus obliteration.
Happy new year, when it comes Kenny |
