| The valley wall is simply the
upland margin and outer edge of the Roanoke River floodplain. The "walls"
range from gentle slopes and terraces to steep bluffs. In some areas the
river is right up against, and still forming, the valley wall, as
exemplified by the 100-foot eroding cliff and bluff seen when paddling by
Fort Branch in Hamilton. Trees that flourish on these edges of the
floodplain are white oak, American beech, tulip poplar, mockernut hickory
and loblolly pine. |
