- Grades list harvest regions, Munsell colour readings, particle sizes and treatment details; Nullarbor Pale is explicitly sold as pale, not red.
Field notes
The catalog distinguishes grades by source and material behavior, not just by colour: Kimberley Pindan is described as self-cementing as it dries, while Simpson Dune is said to settle into panel gaps. Colour entries use separate moist and dry Munsell readings. The site also marks Birdsville Gibber unavailable for the 2026 season, attributing that status to flood-related harvest and access constraints.
