These two cairns presumably lead to whats left of a long forgotten trail that connected the Bulwark Ridge trail with the Stormy Peaks trail. the trail is rarely shown on maps, but two guys we met near the saddle between the Signals (where the trail supposedly begins) said the last recorded traverse of the trail was in 2001. They were hoping to find the trail and see what condition it was in, but finding it in the first place may be the most difficult task.
