At the col, we dropped our packs and started to climb Spider Mountain. This was an unfortunate choice (as outlined in the link). We found the rock to be too unstable, stopped 100 feet short of the summit and started back down. The lack of another experienced person told the tale; had we been able to split the party into two manageable ones, one going to Spider and the other to Mount Formidable, the number of people generating rockfall would be greatly reduced. As it was, with seven novices to supervise it took several hours to safely descend the mountain.
