50% sand · 31% silt · 18% clay

Sandier than 75% of California appellations and clayier than 27%. Each grey point is one appellation’s topsoil; appellations nest, so this is a distribution of places rather than of land.

Plus 28% rock fragments by volume, which the triangle does not describe — the three fractions are of the fine-earth material only.
