(a) Name. The name of the viticultural area described in this section is “Pine Mountain-Cloverdale Peak”. For purposes of part 4 of this chapter, “Pine Mountain-Cloverdale Peak” is a term of viticultural significance.

(b) Approved maps. The three United States Geological Survey 1:24,000 scale topographic maps used to determine the boundary of the Pine Mountain-Cloverdale Peak viticultural area are titled:

(1) Asti Quadrangle—California, 1998;

(2) Cloverdale Quadrangle—California, 1960, photoinspected 1975; and

(3) Highland Springs Quadrangle—California, 1959, photorevised 1978.

(c) Boundary. The Pine Mountain-Cloverdale Peak viticultural area is located in Mendocino and Sonoma Counties, California. The boundary of the Pine Mountain-Cloverdale Peak viticultural area is as described below:

(1) The beginning point is on the Asti map at the intersection of Pine Mountain Road and the Sonoma-Mendocino County line, section 35, T12N, R10W. From the beginning point, proceed southwesterly on Pine Mountain Road to its intersection with a light duty road known locally as Green Road, section 33, T12N, R10W; then

(2) Proceed northerly on Green Road approximately 500 feet to its first intersection with the 1,600-foot contour line, section 33, T12N, R10W; then

(3) Proceed northwesterly along the meandering 1,600-foot contour line, crossing onto the Cloverdale map in section 32, T12N, R10W, and continue to the contour line's intersection with the eastern boundary line of section 31, T12N, R10W; then

(4) Proceed straight north along the eastern boundary line of section 31, crossing the Sonoma-Mendocino line, to the boundary line's intersection with the 1,600-foot contour line on the west side of Section 29, T12N, R10W; then

(5) Proceed northeasterly along the meandering 1,600-foot contour line to its intersection with the intermittent Ash Creek, section 29, T12N, R10W; then

(6) Proceed northeasterly in a straight line, crossing onto the Asti map, to the unnamed 2,769-foot peak located south of Salty Spring Creek, section 20, T12N, R10W; then

(7) Continue northeasterly in a straight line, crossing onto the Highland Springs map, to the unnamed 2,792-foot peak in the northeast quadrant of section 21, T12N, R10W; then

(8) Proceed east-southeasterly in a straight line, crossing onto the Asti map, to the unnamed 2,198-foot peak in section 23, T12N, R10W; and then

(9) Proceed south-southeasterly in a straight line, returning to the beginning point.
