The islands have gone by many names. To the people who call the islands home, Haida Gwaii means Island of the People, it is a shortened version of an earlier name, Haadala Gwaii-ai, or taken out of concealment. Back at the time of Nangkilslas, it was called Didakwaa Gwaii, or “shoreward country.” By any name, the islands are a place of beauty and spirit and enjoy a special place in both the natural and supernatural world.
Haida oral history traces the lineage of their families back to the ocean’s origins. Spear points from Huxley Island confirm a date of between 12,500 - 13,500 years ago. Their stories bear witness to the last ice age, great floods, changes in sea levels and the arrival of the first tree – each binding them closer to the land and sea and enriching our understanding of this special place.
The islands form part of Wrangellia, an exotic terrane that includes parts of western British Columbia, Vancouver Island and Alaska. Today, the mist-shrouded archipelago of Haida Gwaii is separated from the British Columbia mainland by Hecate Strait, a 40-mile wide channel of tempestuous water.
Haida oral tradition tells of a time when the strait was mostly dry, dotted here and there with lakes. And indeed, during the last ice age, glaciers locked up so much water that the sea level was hundreds of feet lower than it is today. Soil samples from the seafloor of Hecate Strait contain wood, pollen, and other terrestrial plant materials that tell of a tundra-like environment. Whether or not the strait was ever completely dry during these times, it seems that it did at least contain a series of stepping-stone islands and bridges that remained free of ice.
