Thanks for the help. As it turned out we decided to avoid Stevens and embark for the remainder of the peaks, which turned out to be a good decision. On Friday, the weather started out very cloudy and misty, with the marine layer rising and falling on us. In the gully leading toward Unicorn, one of our guys (there were three of us) dislodged several 2- to 4-man rocks onto himself, but managed to get away with only a bruised side and a small gash on the leg. We then continued via the route to Unicorn, then headed directly to Boundary (which we never really saw clearly). by the time we arrived back to Unicorn, the weather held for the rest of the day, and we finished off Unicorn, Foss, The Castle and finally Pinnacle, before the evening squall came through. Saturday started out raining, so we bagged the rest (I've done it a few times before anyway - http://www.briankenison.com/images/154).
