LEATHER GLOVES BABY! The thicker the better. As said before once at the bottom of the fixed rope (which is easy to find) stay close to the cliff base for easier travel.
We went down a very moderate and straight forward gully more to the North of this description. It started just behind the old outhouses that used to be there.
However, I have heard that since the fire, the gullys are really choked out and hence the ridge has become the preferred way.
This photo is pretty accurate, but hard to follow by memory if you've never been there. I think on the upper section you should drop into the bowl just a bit earlier (like Paul says). Yes, it's choked, but nothing compared to the bushwack to come at the base of the rope. Do stay close to the wall. That pinnacle is key and easy to see.
This is the best way to get to Mt. Hayden. At the bottom of the cement stairs hop over the left metal railing. Follow faint trail down along ridge. Stay along the ridge after trail fades. Look for a rock caren and natural rock stair case leading down and left into the gully. Once in the bottom wallow to the fixed line. The hard part is over. 6-4-09 Kevin in Fredonia
