The finding of a few pottery sherds with "collared" rims at several Antelope Creek sites was interpreted by Jack Hughes as possible evidence of trade and interaction with Plains Villagers from the Central Plains. This photo compares the four known collared rim sherds from Antelope Creek sites with three Nebraska phase sherds from the Central Plains. While the rims look somewhat similar, technical studies of the paste suggest the Antelope Creek collared-rim pottery was made locally. (On the left, the bottom sherd is from the Cottonwood Creek site, while the other three are from the Roper site.) Photo by Chris Lintz.
