Geographically, the hill is also the highest point of the St Austell Downs, a large region of downland to the north-west of St Austell. The large degree of separation between it and Bodmin Moor to the north-east gives it enough relative height to make it a natural Marilyn, although the official Marilyn has been moved to the top of the highest spoil tip. (its parent is Brown Willy).
