It may also be frowned upon on top of Mt. Cardigan, but it is less so than the Playa. FWIW, Mum is fertilizing some blueberry bushes at the top of Monadnock (which is also forbidden... but she really really loved that mountain, and we were very careful to be quiet about it). We went around some rocks out of site of the park volunteer and scattered ashes, paying attention to wind direction.
