Sand, silt and clay, against every other appellation
Loam
37% sand · 42% silt · 21% clay
Sandier than 27% of California appellations and clayier than 42%. Each grey point is one appellation’s topsoil; appellations nest, so this is a distribution of places rather than of land.
Plus 15% rock fragments by volume, which the triangle does not describe — the three fractions are of the fine-earth material only.
