Sand, silt and clay, against every other appellation

42% sand · 37% silt · 21% clay

Sandier than 53% of California appellations and clayier than 40%. Each grey point is one appellation’s topsoil; appellations nest, so this is a distribution of places rather than of land.

Plus 12% rock fragments by volume, which the triangle does not describe — the three fractions are of the fine-earth material only.
