The Inuit testimony is consistent in locating a very large "tent place" with many bodies, as well as a series of shallow graves just outside it. This is almost surely the "tent place" described to Hall, filled with unburied bodies, along with clear evidence of cannibalism. With the Terror sunk nearby, the working assumption would be that this tent was the final home for many of her crew. Unfortunately, due to years of tidal action, as well as scouring by coastal ice, the surface remains of this site were already gone by the time Frederick Schwatka arrived to search for them in 1879, even though living Inuit elders verified that they had seen them at the spot: "The natives said nothing was to be seen where previously they saw many skeletons and other indications of the white man's camp, as it was so close to the water that all traces had disappeared."
We do, however, know of two items of special significance in the area, both of them associated with Pasty Klengenberg. Klengenberg, the son of Danish whaler/trapper Christian Klengenberg Jorgensen, lived near Terror Bay for some years, operating a small HBC outpost. During his time there, his wife Mary Yakalun came upon a large crumpled metal object. William Gibson believed it was "the remains of a water tank from one of the life boats," but that seems a bit off -- the ship's boats weren't intended as life boats, and I know of no water tanks being standard equipment. However, floatation tanks were a feature of at least some later whaleboat designs (as in the "Montague Whaler" -- thanks to Peter Carney for this suggestion), and earlier ones may well have had that same feature. In addition, it seems that Patsy Klengenberg came upon what Gibson describes as the "grave of a member of the Franklin expedition," which must have somehow been missed by Schwatka and earlier searches. Klengenberg rebuilt the grave marker into a substantial cairn, although no trace of it appears to be known today. It's tempting to connect this with the Peter Bayne story, said to be obtained from a "Boothian native," which also involved a large tent and a row of graves:
Many of the white men came ashore and camped there during the summer; that the camp had one big tent and several smaller ones; that Crozier (Aglooka) came there some times, and he had seen and talked with him; that seal were plentiful the first year, and sometimes the white men went with the natives and shot seal with their guns; that ducks and geese were also plentiful, and the white men shot many; that some of the white men were sick in the big tent; and died there, and were buried on the hill back of the camp; that one man died on the ships and was brought ashore and buried on the hill near where the others were buried; that this man was not buried in the ground like the others, but in an opening in the rock, and his body covered over with something that, “after a while was all same stone”; that he was out hunting seal when this man was buried, but other natives were there, and saw, and told him about it, and the other natives said that “many guns were fired.”
