The boundary, as written into law

Every American wine appellation is defined in federal regulations by walking the boundary landmark by landmark. The official description of this one begins:

. From the beginning point on the south line of Section 2, Township 8 North (T. 8 N.), Range 9 West (R. 9 W.) at the intersection of Arata Lane and Redwood Highway (a.k.a. Old Highway 101), on the "Healdsburg Quadrangle" map, the boundary proceeds: (1) Southeasterly along Redwood Highway through Section 11, T. 8 N., R. 9 W., to the point of intersection with Windsor River Road; (2) Then westerly along Windsor River...
