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) The beginning point is on the Santa Margarita map at the intersection of the northern boundary line of section 10, T29S/R13E, and the Salinas River. From the beginning point, proceed southerly (upstream) along the meandering Salinas River approximately 7.9 miles, crossing onto the Lopez Mountain map, to the river's intersection with the R13E/R14E boundary line, which coincides with the eastern boundary line...
