The best part about this route is the view from the summit. Start at the lowest point of the east face. There are many trees low on this face and a lot of lichen and pine needles, [making] it a bit unpleasant. The nearby east face of the Dreadnaught is cleaner.
Romp up the face. On the upper half, the path of least resistance is a crack/gully in the upper part of the face, although it is certainly possible to stay more on the face. Wander up to the summit ridge, and then scramble up to the table-top summit of Dum. It is easy to get off this summit to the NW, then circle back down to the south to the Fum-Dum col.
