Chautauqua County steep-slope & wetlands.
Chautauqua County rises from the narrow Lake Erie plain up a steep escarpment to vineyard and ski country around its namesake lake. The scarp face and the gulfs cut through it are genuinely steep, and Chautauqua Lake's outlet marshes anchor the county's wetland map.
