A reconsideration of material collected from Promontory Point, north central Utah (Steward 1937) suggests that Promontory-Plains relationships may be closer than hitherto realized. Moreover, while several traits of the Promontory culture occur in more than one Plains archaeological complex, some are limited to the Dismal River aspect, suggesting the possibility of close ties between the Dismal River and Promontory peoples. Steward noted that a few traits (hoop and dart game, hand game boneS, side notched projectile points, end scrapers) represented in the Promontory culture were also found in the Plains. Hill and Metcalf (1941: 188, 197) pointed out that tubular steatite pipes and blunt bone “punches” or “flakers” occurred in both Promontory and Dismal River. This paper enumerates still other resemblances.
