About A.D. 400, the Fremont Culture began to emerge in northern and eastern Utah out of this Desert tradition. The Fremont peoples retained many Desert hunting-gathering characteristics yet also incorporated a maize-bean-squash horticultural component by A.D. 800-900. They lived in masonry structures and made sophisticated basketry, pottery, and clay figurines for ceremonial purposes. Intrusive Numic peoples displaced or absorbed the Fremont sometime after A.D. 1000.
