The geographic origin of Clovis technology: Insights from Clovis biface caches

Multiple hypotheses have been advanced for the geographic origin of the Clovis technocomplex. Several competing hypotheses are considered in relation to the distribution of Clovis caches. Clovis caching behavior is interpreted as a strategy for maximizing exploration and migration rather than an embedded strategy associated with an annual foraging round. Based on this analysis, it is hypothesized that the Clovis technocomplex may have originated along the North Pacific coast or south of the Cordilleran ice sheet in the Puget Lowland before rapidly spreading across the continent.
