Found by my friend in Eagle Rock Reservation, he was kind enough to give it to me. As per the genius skull collector Alan Dudley (the book is Skulls by Simon Winchester gifted to me by Kerfe and an invaluable reference) I soaked the skull in a bucket for many weeks to clean it. At first I thought it looked like a large dog such as a Rottweiler. Now I think it is probably a wolf.
