Jeff Clark thought the existing maps of the Salish Sea didn’t have enough detail. So he set out to make a much more detailed map, “to increase the geographic literacy of the area.” This meant not only showing the natural features, but also the human-made ones. And not just cities — he thought it was important to include details like the traditional lands of coastal First Nations. The result is The Essential Geography of The Salish Sea, a wall-sized map that gives viewers a “big picture view” of the Salish Sea bioregion, which stretches from Puget Sound near Seattle to the Pantheon Mountain Range, 300 kilometres up the coast from Vancouver.
