A recently driven sewer tunnel west of Blackburn has shown the presence of a thick turbidite sequence between the R. gracile and R. bilingue Goniatite Bands. Above the R. bilingue Band, turbidites pass up through delta slope deposits into delta top fluviatile sandstones, derived from the northeast. The section provides evidence for the westward limit of advance of the pre‐ R. gracile Kinderscoutian delta slope and also enables a more accurate R 2 isopachyte map to bc drawn.
