Is the navigator the East Face.. that looks wicked hard!
the nav wall goes up a sub summit to the east of the east pillar.
both are ED1, both are hard.
the one positive of the east pillar may be the additions of fixed gear (20 year old bolts and pitons), while the nav wall has not a single piece of anything resembling fixed gear, prior ascents, hints of human life, etc.

but really those are just warm ups for the real hard climb on slesse, the NE Face.
