Pete and I grovelled up this mtn via Stoneworks Canyon.  The scree is horrendously loose in places, so I advise heading for either the SW or S ridge as soon as feasible.  The SW ridge has moderate scrambling.  Slopes are steeper than the map lets on.  Not sure on the likelyhood of being able to continue to the N summit as clouds closed in, but it looked like a steep difficult downclimb of some distance, then a long walk to the other summit.
