By 1910, Pacific Lime Company and BC Cement had set up limestone quarrying operations at Blubber Bay and Marble Bay. For almost a century, limestone quarrying continued. Much of the product was shipped to Seattle, Oregon or California. Railways, cableways and concentration plants were built for the mines, as was the arbutus-shaded company town of Blubber Bay. Limestone pits were dug all around the north section of the island. Lime kilns for sintering quicklime were raised around the northern end of the island.
