Outstanding photos, really, and welcome to the forums. Actually, I'm impressed with how similar a feel for the North American Pacific Northwest some of those shots have (minus the trees, of course). Here's two photos from Mt. Hood in Oregon to show you what I mean:
I love it when the evening clouds roll in, a fairly common occurrence here, and fairly rare in most of the states. There's a certain 'moisture content' similarity with Scotland that you don't find in most other parts of the states. I am of Scottish descent, and my mother told me our ancestors moved to Eugene, OR in part because of the similar climate.
I look forward to learning more about your wet-weather techniques above timberline; much of what is discussed around here revolves around the drier parts of the American West.
