One of the most distinctive burial methods on the Northwest Coast was the creation of platforms in trees, on which coffins would be placed. While the practice is commonly recorded and discussed in the Anthropological literature, photographs of tree “burials” are rare — and even if they were not, then reproduction of these images might well be problematic.
I recently ran across the image above by the little-known Canadian author Joanna Simpson Wilson (1896-1987), which shows numerous bentwood boxes attached to trees as a throng of mourners gathers below. The platforms are rather insubstantial and the coffins are stacked several-high in places, with red cloth attached — perhaps the remains of blankets. After a number of years, the boxes would deteriorate and the remains of the body would fall from the tree. At this time, a secondary burial at a village site cemetery or other place might be performed. I have seen the remains of several tree burials in the field, with human remains scattered beneath the branches of a large spruce — looking up, there are large branches with ring-like pathologies where the bark grew around rope, and other evidence of cultural modification. Archaeologically, there is a trend over the long term along the coast for inhumation of human remains to give way to sky burials or mortuary houses.
According to this site, the setting of the painting is the Kwakwaka’wakw village of Tsaxis (near Fort Rupert / Port Hardy on Vancouver Island), specifically a place called Storey Beach (more pics).
