Khatadin - it's usually in the cloud line and it's a collapsed volcano... it's extremely atmospheric to pick your way across large lava boulders on the peak ridge in a dense fog cloud.
The first time I climbed Mt. Washington some friends took me, and I had no idea there was a road to the summit. It was so disappointing to reach the top and find a parking lot full of "This Car Climbed Mt. Washington" bumper stickers.
