Most
archaeologists believe the Fremont developed out of existing groups
of hunter-gatherers on the Colorado Plateau and in the eastern Great
Basin. These small groups were, like their Fremont descendants, diverse,
flexible, and adaptable. They ranged from fairly large and relatively
sedentary populations in environments where resources were more readily
accessible, to small, highly mobile family-sized groups where resources
were widely dispersed. Over a span of about a thousand years, from sometime
after 2,500 years ago to about 1,500 years ago, different groups of
these hunter-gatherers gradually adopted, in a piecemeal fashion, many
of the traits associated with the farming societies of the Southwest
and Mexico.
First,
corn and other cultivated plants (called domesticates), initially developed
in what is now Mexico, then diffused northward throughout the greater
Southwest and were added to the wild food subsistence base of native
people sometime about 2,500 to 2,000 years ago in areas on either side
of the southern Wasatch Plateau. This early use of corn and other domesticates
occurred well before settled villages developed, and it seems that farming
at first was just a part-time affair practiced by people who were still
essentially nomadic hunters and gatherers. The earliest "Fremont" corn,
radiocarbon dated to 2,340-l,940 years ago, comes from a cache near Elsinore, Utah; corn in sites along Muddy Creek in the San Rafael Swell date to just after the time of Christ. These sites suggest that farming
was well established in some areas by 2,000 years ago. Outside this
region, however, full-time hunting and gathering lifestyles seem to
have continued unchanged. For example, in the deserts of the eastern
Great Basin, at all of the many cave sites like Fish Springs, Lakeside, Black Rock, and Danger Cave, domesticates are absent throughout this
early period and subsistence was based entirely on wild foods.
