Sand, silt and clay, against every other appellation

CLAYSANDSILT

Sandy loam

67% sand · 22% silt · 11% clay

Sandier than 97% of California appellations and clayier than 1%. Each grey point is one appellation’s topsoil; appellations nest, so this is a distribution of places rather than of land.

Plus 9% rock fragments by volume, which the triangle does not describe — the three fractions are of the fine-earth material only.
