    A cirque isn't a rock; it's an amphitheatre-like bowl that forms the head of a glacial valley. An example that's relatively local to me:

    Cwm Idwal

    Cirques are formed through plucking and abrasion, basically. The speed of its formation would depend upon how fast the glacier is flowing, more than anything, I would imagine.

    EDIT: Oh ****, sorry. Misread your first sentence. Not sure that I know what would affect the distinctiveness of a cirque. Uplift rate? Accumulation rate? How fast the glacier's flowing?
