The people of the Haida Nation have occupied and collected food and materials from Damaxyaa since time immemorial. A seasonal camp known as Kil was originally located at the mouth of Haans Creek on Shingle Bay just to the north of the heritage site/conservancy. Another seasonal camp known as Skena (Sge’na) was located just to the east of the heritage site/conservancy on the shores of Hecate Strait.
The village of Sandspit is the closest community to Damaxyaa Heritage Site/Conservancy. It borders on the northern and eastern sides of the heritage site/conservancy.
The terrestrial component of the heritage site/conservancy covers 822 hectares. The elevation range is from sea level to 289 metres. The marine component/foreshore area covers an area of 7 hectares.
The marine foreshore area has high intertidal values with surfgrass habitat, and eelgrass beds, kelp forest areas and eighteen estuaries that spill into some of the most productive marine habitat on Haida Gwaii. The nearshore marine area is a small portion of the overwintering habitat for Brant geese where they feed primarily on eel grass.
