All of the artifacts of the McClallum Middle Fraser Collection were found on the McClallum farm a few miles northwest of Agassiz, British Columbia. A large habitation site is located on the farm on a ridge facing what may once have been a water connection between Harrison Lake and the Fraser River. This habitation site was mapped in 1945, and has been described elsewhere. In that year, the Columbia University Summer Field Party studied the collection and introduced Mr. McClallum to Mr. A. E. Pickford, then of the Provincial Museum, Victoria, who joined the party for a few days. The collection was moved to the museum under his direction.
