Or would the grainier (snowy) material be in Roncevaux Terra with more small shadowed areas between grains that help contribute to the opposition effect? I would surmise then that CR is less granular, perhaps more tarry or something. The actual size of the grains may be less important in deciding whether there's an opposition effect.
