Deception Pass and Packer Pass both connect the Ptarmigan Lake valley with the head of the Skoki Valley. They are similar in elevation and are separated by a high point known as Packer Peak.
In 1930, Cliff Whyte, Fulton Dunsmore, Tex Woods, and Cyril Paris travelled up the Ptarmigan Valley and over Deception Pass. Paris named it during this trip, calling it the most deceptive thing I ever climbed!" ("Skoki" by Kathryn Manry)
