Geochemical Evidence for Long-Distance Exchange
From Loess Plains to High Plains: The Westward Movement of Upper Republican Pots
Abstract
Wedel's initial evaluation of the Upper Republican culture in Nebraska stated his doubt that the culture extended westward on the Republican River drainage beyond Frenchman Creek. The discovery of such sites well onto the High Plains of Colorado and Wyoming negate this early claim, and create problems relating to the nature of subsistence, migration and exchange in late prehistory. Previous research surrounding this problem has focused on Upper Republican ceramic assemblages from the High Plains, which are virtually indistinguishable visually from their Central Plains counterparts. Geochemical evidence and a multi-regional approach to examination of ceramic assemblages in Nebraska, Colorado, and Wyoming help to clarify the issue of High Plains Upper Republican, highlighting evidence of inter-regional interaction between hunter-gatherers and subsistence horticulturalists.
