The Nanaimo Group is an assemblage of conglomerate, sandstone, siltstone, shale, and minor coal deposited in the Nanaimo Basin during Santonian through Maestrichtian time (Muller and Jeletzky, 1970; Ward, 1978). It crops out on southeastern Vancouver Island, the Gulf Islands of British Columbia, and the San Juan Islands of Washington (Figs. 1, 2).

Good exposures are also present along roadcuts and major rivers on Vancouver Island.
