Yes, I have done Mt. McKinley. (By the way, the peak is named McKinley. It's located in Denali National Park.) It was 1977,and I was 38 at the time. It would not be a good idea for an inexperienced person to attempt such a mountain. Would you know how to detect a crevase? Would you be able to rescue someone who fell into a crevase ? Would you be able to rescue yourself? People die every year on McKinley.
We had to perform one crevase rescue on our trip. He was the middle person on a rope of three and was (fortunately) not injured.
