From Ancient Roots to Modern Nation
Our history in the northwestern watersheds of British Columbia spans thousands of years. We have lived on and cared for this land since time immemorial, and continue to do so today.
Led by Hereditary Chief Darlene Simpson (Skii km Lax Ha), we are descendants of the Laxwiiyip Tsetsaut, an Athapaskan-speaking people living throughout parts of the Nass River, Skeena River, Bear River, and Stikine River watersheds.
Our history is one of resilience and adaptation. We have maintained our presence in our traditional territories, preserving our unique culture and exercising our inherent rights to our ancestral lands. Our Nation is guided by traditional laws and practices that have evolved to meet the needs of our people in the modern world.
We are committed to sustainable stewardship, economic development, and the ongoing practice of our cultural and political traditions. As custodians of our ancestral territories, we work to protect the land, waters, and resources for future generations while pursuing opportunities that benefit our people.
Honouring Our Past, Shaping Our Future
