Lithology and environment
Primary lithology: mudstone

Lithology description: "Alternating mudstone and sandy siltstone; groove casts and load casts; small cross laminae and convolute lamination in siltstone."
Environment:marginal marine indet.
Geology comments: "Waterston (1979) tentatively interprets this as a marginal marine setting. The described sedimentary features are compatible with, but not diagnostic of, a tidal flat setting. BA 1"
