The Grasberg unit is the lowest layer of the Burns Formation, the stack of sulfate-rich sandstones seen all over Meridiani. They sit on top of the layer of debris eroded off the Endeavour rim hills. The scarp here, the little step up above the bench, is presumably that eroded debris. The exact relationship is not easy to figure out just looking at the images here, but it seemed to be clearer at the north end of Cape York.
More interesting to me is the origin of the basalt boulders like Tick Bush. Are they ejecta thrown in from a distant impact? I don't see any sign of basalt flows in the vicinity. Phil -------------------- ... because the Solar System ain't gonna map itself.
