The piedmont landscape of Maryland: a new look at an old problem

Auteurs :
COSTA, J. E.

Description :
The piedmont upland of Maryland has been variously interpreted as a peneplain, a series of peneplains, a surface of marine planation, and a landscape in dynamic equilibrium. Coastal plain clastic wedges, truncated weathering stratigraphy, truncated marble lowland gravel horizons and distribution of stream gradients and floodplains indicate that erosion in the Maryland piedmont has not been uniform over long periods. The upland surface of low relief in the present piedmont landscape appears to be a feature that dates back to the Late Miocene.
