Hard to tell from your photo, and even from your SPOT, but you may have been even closer on BK than you thought:
Thanks. But no, I was a long way from the peak. See the two pictures above the green rock. The two shown on the summit are on that far point in the picture above them. I would have had to down-climb over really treacherous loose rock, then picked my way for half a mile on third and forth class rotten rock. I am sure I made the wise decision to descend back to camp. THAT was hard enough for me!
