The Green Butt Skunk is one of the most popular and proven steelhead patterns. The original Skunk was possibly originated in the 1930's by Wes Drain on the Stillaquamish River in Washington. The original wing was real black and white skunk hair, which makes you wonder just how far fly anglers will go to catch a steelhead. Many years later the green butt was added and someone wisely changed the winging material from skunk to calf tail, and the Green Butt Skunk found its way into steelheading history and just about every fly box in the Northwest and beyond. Today it is tied in countless variations, and every tier has their own version, but this is a fairly standard Green Butt Skunk recipe.
