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:

(1) From the beginning point at the southeast corner of quadrant 36 and southwest corner of quadrant 32 (a point where Mendocino and Lake Counties border on the T. 17 N.-T. 16 N. township line), the boundary runs northwest to the northeastern corner of quadrant 4, on the T. 18 N.-T. 17 N. township line; (2) Then west to the northwest corner of quadrant 1; (3) Then south to the southwest corner of quadrant 36; (4)...
