Abraham Mountain is a b*tch. This is one of my least favorable scrambles to date. Endless painful side-hiling along the loose rubble slope and multiple slabby drainage, followed by a slog up the Endless Scree Gully of Pain, which lived up to its name, followed by another long side-hilling along a steep ledge with loose rubble, finished with a scree bash to the summit. There is no value to this scramble beside the great summit views. However, the summit views are very similar to those from adjacent Windy Point Ridge, which offers fantastic scrambling on good rock.

This scramble can be more enjoyable when the Endless Scree Gully of Pain is covered with snow (read May or early June), and possibly if sticking to the creekbed as far as possible instead of the painful side-hilling above it. (It is worth of noting that the ledges below the summit block can be dangerous if covered with snow.)

Once on the summit, I noticed an interesting potential route on the north side of the mountain, which seems to offer a delightful ridgewalking. I'm tempted to attempt it sometime in the future.

It's hard to rate this route. Technically, there is no real hand-on scrambling. It's just an endless slog. However, due to the looseness of the terrain, there are quite a few spots where a minor rock slide can end your life by pushing you off the cliffs.

P.S. After talking with a few folks you had done it before, I realized there is a more enjoyable way to the top, a combination of the routes taken by Rafal Kazemierczak and Josee Menard:
1. Follow the creekbed as long as you can. This involves an exposed scrambling to bypass a waterfall.
2. Take the major drainage (left gully) all the way to the col. Hopefully, it has holds snow. Don't take the gully on the right side (Vern Dewit's route, see his photo: http://www.explor8ion.com/sites/default/files/images/scrambles/abraham/abraham-075r.jpg)
3. From the col follow the ridgeline to the summit.
