Sandier than 29% of California appellations and clayier than 79%. Each grey point is one appellation’s topsoil; appellations nest, so this is a distribution of places rather than of land.
Plus 21% rock fragments by volume, which the triangle does not describe — the three fractions are of the fine-earth material only.

The appellation in federal law
The boundary, in the government’s own words (154 words)
(c) Boundaries. The Green Valley viticultural area is located in Solano County, California. The beginning point is the intersection of the township line identified as T6N/T5N with the westernmost point of the Solano County/Napa County line on the north border of Section 4, located on U.S.G.S. map “Mt. George Quadrangle.” (1) From the beginning point, the boundary runs in a southerly direction along the Napa/Solano County border to State Road 12; (2) Thence east along State Road 12 to where it intersects with Interstate 80; (3) Thence southwest on Interstate 80 to where it intersects with the Southern Pacific Railroad track; (4) Thence in an easterly direction along the Southern Pacific Railroad track to where it intersects with range line “R3W/R2W”; (5) Thence due north on range line “R3W/R2W” to where it intersects with the Solano County/Napa County line; (6) Thence due west along the Solano County/Napa County line to the point of beginning.
The rule qualifies the name: Solano County.
