AbstractSimilar diagnostic artifacts from the Promontory Cave sites in Utah and from Franktown Cave in Colorado have been interpreted as evidence of a pre-A.D. 1300 migration of proto-Apachean speakers into the Rocky Mountain west using both Intermontane and Plains margin migration routes. A suite of AMS dates on perishable objects, including an almost complete moccasin, indicates the site was occupied for 40-85 years in the early A.D. 13th century just prior to the occupation of Promontory Cave 1 during the late 13th century. The nearly identical timing of the onset of Promontory Culture occupation of sites 700 km apart, coupled with analogous moccasin types and other artifacts indicative of Subarctic roots, both favor a common Dene origin for the occupants.  Evidence suggests that these people occupied a large area along the foot of the Rocky Mountains and traveled widely through it, establishing trade relationships among themselves and with more sedentary groups of people on the plains.

AbstractFlattened, S-shaped or crescent-shaped wooden artifacts with longitudinal grooves on both faces and a pitched wrap on the handle are known from widely scattered locations throughout the greater Southwest. They were first described as grooved clubs from the important site of White Dog Cave in NE Arizona and formed part of the essential trait list of Basketmaker II culture (Guernsey and Kidder 1921).

Although somewhat resembling historic Puebloan rabbit sticks, Guernsey and Kidder argued against such an interpretation based on a lack of appropriate use-wear. The speculative alternative function for the artifacts was as defensive implements to bat away atlatl darts. This “fending stick” interpretation was extended to Mesoamerica where the artifacts are known from art and materials recovered from the Sacred Cenote at Chichén Itzá.  This talk will examine the role of these distinctive artifacts in the Southwest and Mesoamerica and their significance for understanding Basketmaker II origins and intergroup conflict.
