Russell is very exposed in places, but the climbing is only class 3 (if you do it right). Granite required a lot of class 3 and class 4 climbing. There were places where I did class 5 moves, but I could have kept it to class 4 with a bit more route-finding effort. I had rock shoes, and the climbing was really fun!
For those of you that don’t know, I dayhiked Mt. Humphreys last summer with Climby and four other people. We were all successful, but we spent considerable time screwing around with a rope. If I remember right, Granite had more rock climbing than Humphreys, and it may have been a little harder.
It was a brutal 16-hour day with rock shoes and no rope 25 years ago, when I was younger and faster. If you bring a rope, plan on an overnight trip. Choose carefully when you decide whether to bring a rope, rock shoes, both, or neither.
