# §9.143. Spring Mountain District.

- (a) **Name.** The name of the viticultural area described in this section is “Spring Mountain District.”
- (b) **Approved maps.** The appropriate maps for determining the boundary of the Spring Mountain District viticultural area are four U.S.G.S. 7.5 minute series topographical maps of the 1:24000 scale. They are titled:
  - (1) “Kenwood, Calif.,” 1954 (photorevised 1980).
  - (2) “Rutherford, Calif.,” 1951 (photorevised 1968).
  - (3) “St. Helena, Calif.,” 1960 (photorevised 1980).
  - (4) “Calistoga, Calif.,” 1958 (photorevised 1980).
- (c) **Boundary.** The Spring Mountain District viticultural area is located in Napa County, California, within the Napa Valley viticultural area. The boundary is as follows:
  - (1) Beginning on the Calistoga quadrangle map at the Napa-Sonoma county line at the boundary line between sections [18](/cfr/27/18.md) and [19](/cfr/27/19.md) in T8N/R6W.
  - (2) Then east along the boundary line between sections [18](/cfr/27/18.md) and [19](/cfr/27/19.md) for approximately 3/4 of a mile to its intersection with Ritchie Creek at the boundary line between sections [17](/cfr/27/17.md) and [20](/cfr/27/20.md).
  - (3) Then northeast along Ritchie Creek approximately 2 miles, to the 400 foot contour line in the northeast corner in [section 16](/cfr/27/16.md) of T8N/R6W.
  - (4) Then along the 400 foot contour line in a northeast then generally southeast direction, through the St. Helena and Rutherford quadrangle maps, approximately 9 miles, past the town of St. Helena to the point where it intersects Sulphur Creek in Sulphur Canyon, in the northwest corner of [section 2](/cfr/27/2.md) in T7N/R6W.
  - (5) Then west along Sulfur Creek (onto the Kenwood quadrangle map) and south to the point where it first divides into two intermittent streams in [section 3](/cfr/27/3.md) in T7N/R6W.
  - (6) Then south along the intermittent stream approximately 1.5 miles to the point where it intersects the 2,360 foot contour line in [section 10](/cfr/27/10.md) in T7N/R6W.
  - (7) Then southwest in a straight line, approximately .10 mile, to the unnamed peak (elevation 2600 feet) at the boundary line between Napa and Sonoma Counties.
  - (8) Then in a generally northwest direction along the Napa-Sonoma county line, through sections [10](/cfr/27/10.md), [9](/cfr/27/9.md), [4](/cfr/27/4.md), [5](/cfr/27/5.md), [32](/cfr/27/32.md), [33](/cfr/27/33.md), [32](/cfr/27/32.md), [29](/cfr/27/29.md), [20](/cfr/27/20.md), and [19](/cfr/27/19.md), to the beginning point on the Calistoga quadrangle map at the boundary between sections [18](/cfr/27/18.md) and [19](/cfr/27/19.md) in T8N/R6W.
