Sand, silt and clay, against every other appellation

CLAYSANDSILT

Sandy clay loam

52% sand · 28% silt · 20% clay

Sandier than 77% of California appellations and clayier than 34%. Each grey point is one appellation’s topsoil; appellations nest, so this is a distribution of places rather than of land.

Plus 8% rock fragments by volume, which the triangle does not describe — the three fractions are of the fine-earth material only.
