47% sand · 33% silt · 20% clay

Sandier than 69% of California appellations and clayier than 33%. Each grey point is one appellation’s topsoil; appellations nest, so this is a distribution of places rather than of land.

Plus 17% rock fragments by volume, which the triangle does not describe — the three fractions are of the fine-earth material only.
