It reaches Allen Brook in about a half hour. This photo is of Allen Brook 150 ft. above the point where the trail first intersects it. From this point onwards, the trail follows the brook straight up the mountain. Further up the slope it becomes more apparent that Allen Brook is following a slide. The path begins to cross back and forth across the slide.
Cairns mark the path in spots where useful.
Previously, plastic markers had been used. We did not see any of these. While the falls in the photo is a bit higher than most, there are a number of nice falls to be seen on the way up. One of our party on the Allen slide. While steep, it's quite short.
