 Ahtahkakoop's band was part of the Fort People ("wāskaahikaniyiniwak"), so called for their close proximity to Fort Carlton.The territory of the Fort People spanned north, west, and south-west of Fort Carlton, although Ahtahkakoop's typical hunting grounds were located north of the Bad Hill ("maci-waciy"), north-west of modern-day Rosetown.The other major chief of the Fort People at this time was Mistawasis.
