Abstract 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). Nearly continuous outcrops of the Namaimo Group occur along seacliffs on Vancouver Island, and on the Gulf and San Juan islands. Good exposures are also present along roadcuts and major rivers on Vancouver Island. Ferries from the mainland to Vancouver Island and most of the Gulf and San Juan islands can be boarded at Anacortes, Washington, and Tawassen, British Columbia, and taken to Sidney, British Columbia (approximately 20 mi, 32 km, north of Victoria on Vancouver Island), and to the San Juan and Gulf islands, respectively. Ferries can also be taken from Port Angeles, Washington, to Victoria, British Columbia. In addition, ferries run regularly between islands in both Canada and Washington. Current ferry schedules are necessary for travel in this area. Tidelands are considered public property in both Canada and the United States; access to the outcrops is available at many public beaches.
