Lewis County steep-slope & wetlands.
Lewis County runs from the wetland-heavy Tug Hill Plateau across the Black River Valley to the western Adirondack foothills. The valley floor is flat and farmable; the plateau edge and foothill parcels climb quickly, and DEC wetland mapping is dense across the Tug Hill's headwater swamps.
