Comments:
Segment appears to be located on a post-glacial alluvial fan. Old mill site remains in segment; some of the stonework is relatively intact. Historic incision in vicinity of old mill (combined with more confined true valley wall US) leaves stream largely flowing in effective Narrow valley, but confining terrace off RB may be topped in high level floods. This terrace is far enough off RB that incision ratio does not change stream type from C (entrenchment ratio 4.9, so no STD), but flood flow forces are elevated through this segment.
