The Green Butt Skunk has accounted for numerous fish, and since its inception around the 1950s by Dan Callaghan, it has become one of the most effective and popular steelhead flies of all time. Dan Callaghan modified the original Skunk pattern and spiced it up with a green butt. Ever since many steelheaders will have a Green Butt Skunk in their fly box.
