If the people who accumulated the burial assemblage were ranging across an area that covered multiple geological stone sources at significant distances from the burial site, they were covering territory on a scale that modern hunter-gatherer research suggests is typical of mobile peoples pursuing large game in open environments.

This kind of mobility would have meant that the social group associated with the Anzick burial was in contact — directly or through exchange networks — with other groups across a large area.

The Clovis technological tradition’s consistency across the continent makes more sense in the context of such networks: if groups were in regular contact, the transmission of technological innovations would have been facilitated, and the maintenance of a broadly consistent technological style across a wide geographic area would have been possible.
