Sand, silt and clay, against every other appellation

CLAYSANDSILT

Clay loam

28% sand · 37% silt · 35% clay

Sandier than 4% of California appellations and clayier than 97%. Each grey point is one appellation’s topsoil; appellations nest, so this is a distribution of places rather than of land.

Plus 3% rock fragments by volume, which the triangle does not describe — the three fractions are of the fine-earth material only.
