Sand, silt and clay, against every other appellation
Sand
90% sand · 5% silt · 5% clay
Sandier than 100% of California appellations and clayier than 0%. Each grey point is one appellation’s topsoil; appellations nest, so this is a distribution of places rather than of land.
Plus 2% rock fragments by volume, which the triangle does not describe — the three fractions are of the fine-earth material only.
