Truly immense sights.....

[Ozzy]

I used to live just about 60 miles from St. Helens. Pretty neat. Of course, I lived there long after the eruption so the only thing I have to compare it to are the surrounding mountains.
But in the same area, while maybe not necessarily a natural wonder, Multnomah (sp?) Falls is pretty damned impressive.
Also, one of the things I hope to see in person before I die is Angel Falls in Venesuela. The largest waterfall in the world, over 1/2 a mile tall.

That's gorgeous Ozzy.

This picture does not do justice to seeing it for real. I had to make this panoramic from 4 or 5 pics.

Loch Ness.
