St. Lawrence County steep-slope & wetlands.
New York's largest county descends from Adirondack foothills around Star Lake to the broad, flat St. Lawrence Valley. Most agricultural parcels in the north are gentle, but the southern towns carry real relief — and the county's river corridors and fens rank among the most extensive wetland systems statewide.
