I see all your wonderful photographs from these extraordinary places. They are great. But I wonder if you have some 'mountain goat' mobility to walk into these places? How do you manage it (particularly when carrying photo gear)?

I am definitely not mountain goat material. I am afraid of heights actually. That one shot looks worse than it was, but it was not safe. The lens exaggerates the foreground. I was only up a few feet maybe four, off flat ground. But it was not stable for sure.For that shot, I had my camera and tripod. Backpack was on the ground close by. I would not have done that shot with a backpack.
