I'm sorry for your loss, but you're a good son. I can't think of a nicer place to hang out for an eternity or two. My folks took a sail in the Atlantic together after they'd both passed...
I spent a lot of time up there hiking, climbing, and cross country skiing back in 1980-83. It can be a dangerous place at times, and I had a couple of close calls. It's much nicer to think about staying there forever the way you've done it for your mother.
