Named for exposures along Huling Creek, Shasta Co, CA. Is unit in Ono formation (new). Composed of mostly graywacke; mudstone and thick extremely lenticular conglomerate units interbedded in lower part. Upper 500 ft of tongue contains GABBIOCERAS WINTUNIUM Zone, Horsetown Stage fossils. Lower contact of tongue usually very distinct; lower beds form north-facing cuesta-like escarpment overlooking less resistant mudstone of lower part of Ono formation. Underlies mudstones with gradational contact. Is Late Cretaceous age.

Upper 850 ft of Huling "tongue" of Ono Formation (Murphy, 1956) is raised in rank as Huling Sandstone Member and assigned to Budden Canyon Formation (new). Mudstone and conglomerate beds of original "tongue" are excluded since they may be more related lithologically, spatially, and temporally to Roaring River or Chickabally Members. Recognized as far south as Big Salt Creek in northernmost Tehama Co, CA.
