Sand, silt and clay, against every other appellation

CLAYSANDSILT

Sandy loam

55% sand · 30% silt · 15% clay

Sandier than 82% of California appellations and clayier than 10%. Each grey point is one appellation’s topsoil; appellations nest, so this is a distribution of places rather than of land.

Plus 21% rock fragments by volume, which the triangle does not describe — the three fractions are of the fine-earth material only.
