In recent work, two hypotheses were proposed to explain the formation of distinct scroll bars and subsequent floodplain ridges on the Beatton River. These hypotheses are reassessed here in the light of recent field observations, which suggest that an initial scroll bar may form around a stranded dead tree that acts as a sedimentation nucleus on a point‐bar platform.
