Geography comments: "within the Gatineau Park limits"
"Radiocarbon dates on wood charcoal are 2951 ± 200 years BP (UQ-1652) at 50 cm, 4855 ± 110 years BP (GSC-5352) at 90 cm, 3383 ± 140 years BP (UQ-1958) at 110 cm, and 7635 ± 40 years BP at 250 cm (Beta-93668)" (presumed to be uncalibrated because errors are symmetrically distributed)

Environment
Lithology: sandstone
Taphonomic context: bird accumulation,cave
Habitat comments: "The sediments in the upper infill are coarse with a brownish colour" with "a dominance of sandy material"
"Some" of the animals "lived and died in the cave or that tumbled in and perished there" and others "probably represent animals that were consumed by avian predators" with no apparent mammalian predation
