I went hiking in NCNP with a friend from Switzerland, off SR 20. When we summited and could see from Mount Baker to Mount Rainier, he said it looked like the Alps, except it would include parts of Italy, France, Germany and Switzerland.

Switzerland. 15,943 sq mi Washington 71,362 sq mi

He was also surprised at the amount of snow in the summer, and the lack of infrastructure in the park. He was surprised that the creeks were not bridged.
