- KkLn-2, Grant Lake: This is a probable fall caribou hunting location attributed to the Agate Basin complex. Details of composite sample S-1056: CMC-808 (16.5 g), square A, feature 1, tent ring with most of the bone from the hearth floor; CMC-809 (20.5 g), square A, general scatter within the unit; CMC-810 (22.8 g), square B, feature 1, tent ring with most of the bone from the hearth floor; CMC-811 (36.3 g), square B, general scatter within the unit; CMC-812 (36.1 g), square C, feature 2, hearth floor in tent ring. Even by combining the five samples, the composite sample of charred bone was quite small, and the result is a large error (+/-850). The pretreatment method used at the time would have sought to extract collagen in an insoluble form, and this method was later suspected to yield ages somewhat too recent. S-811 should have dated the earliest possible time for human occupation.
