Beautiful view! I never think of Washington as being mountainous.
You must be thinking of Washington, DC (g)
Actually, this Washington has it all. The ocean, Puget Sound, mountains including 14,410 foot Mt Rainier, Mt Adams at around 12,000 feet, Mt Baker and Glacier Peak, around 10,000 feet, St Helens which blew its top, and many many others. I have been to the top of all of them. Adams twice and Mt St Helens before and after it blew. Lots of our dayhikes can gain 3,000-4,000 feet. But then beyond the Cascade Curtain (as our brethren in Eastern Washington call it) are desert areas.
