I do not know how this stretch of the Southwest Mabou River came to be lined with boulders on its east side, but they stand out, both in this photo (which looks upstream) and as one walks the trail, which can be seen at the left of this photo above the river. It seems unlikely that they got there by natural forces, since one doesn’t see them on other stretches of the river; perhaps they were placed there by those who built the railway at the beginning of the 20th century to guard against wash-outs of the railroad bed.
As can be seen here, the ridge at the left has begun moving away from the river, opening up a marsh on the east outside the scope of this photo.
