Sand, silt and clay, against every other appellation
Sandy loam
66% sand · 22% silt · 12% clay
Sandier than 96% of California appellations and clayier than 3%. Each grey point is one appellation’s topsoil; appellations nest, so this is a distribution of places rather than of land.
Plus 41% rock fragments by volume, which the triangle does not describe — the three fractions are of the fine-earth material only.
