(a) Name. The name of the viticultural area described in this section is “The Rocks District of Milton-Freewater”. For purposes of part 4 of this chapter, “The Rocks District of Milton-Freewater” and “The Rocks of Milton-Freewater” are terms of viticultural significance.

(b) Approved maps. The two United States Geological Survey 1:24,000 scale topographic maps used to determine the boundary of The Rocks District of Milton-Freewater viticultural area are titled:

(1) Milton-Freewater, Oreg., 1964; and

(2) Bowlus Hill, Oreg., 1964; photoinspected 1976.

(c) Boundary. The Rocks District of Milton-Freewater viticultural area is located in Umatilla County, Oregon. The boundary of The Rocks District of Milton-Freewater viticultural area is as follows:

(1) The beginning point is found on the Milton-Freewater map at the intersection of an unnamed medium-duty road known locally as Freewater Highway (State Route 339) and an unnamed light-duty road known locally as Crockett Road, section 26, T6N/R35E. From the beginning point, proceed east-southeasterly in a straight line for 0.8 mile to the intersection of State Highway 11 (Oregon-Washington Highway) and an unnamed light-duty road known locally as Appleton Road, section 25, T6N/R35E; then

(2) Proceed southeasterly in a straight line for 1.05 miles, crossing onto the Bowlus Hill map, to the intersection of three unnamed light-duty roads known locally as Grant Road, Turbyne Road, and Pratt Lane on the common boundary between section 36, T6N/R35E, and section 31, T5N/R36E; then

(3) Proceed southwesterly in a straight line for 1.1 miles, crossing back onto the Milton-Freewater map, to the intersection of the Union Pacific railroad tracks with the Walla Walla River, section 1, T5N/R35E; then

(4) Proceed southwesterly and then west-northwesterly along the Union Pacific railroad tracks for 1.2 miles to the intersection of the railroad tracks with the 980-foot elevation contour line, approximately 0.15 mile west of Lamb Street, section 2, T5N/R35E; then

(5) Proceed west-northwesterly in a straight line for 2.25 miles to the intersection of the 840-foot elevation contour line and an unnamed light-duty road known locally as Lower Dry Creek Road, section 33, T6N/R35E; then

(6) Proceed northwesterly in a straight line for 0.8 mile to the intersection of the 800-foot elevation contour line with an unnamed light-duty road running north-south in section 32, T6N/R35E; then

(7) Proceed easterly in a straight line for 0.9 mile to the intersection of the 840-foot elevation contour line with the Hudson Bay Canal, section 33, T6N/R35E; then

(8) Proceed due north in a straight line for 0.25 mile to the line's intersection with Sunnyside Road, section 33, T6N/T35E; then

(9) Proceed northeasterly in a straight line for 0.5 mile to the intersection of the 840-foot elevation contour line with an unnamed medium-duty road known locally as State Highway 332 (Umapine Highway), eastern boundary of section 28, R6N/T35E; then

(10) Proceed east-northeasterly in a straight line for 0.3 mile to the intersection of three unnamed light-duty roads known locally as Triangle Road, Hodgen Road, and Appleton Road, section 27, T6N/R35E; then

(11) Proceed east-northeasterly in a straight line for 1.25 miles, returning to the beginning point.
