period is from 500 BCE – 100 CE, perhaps more indicative of the degree of technology and culture capabilities than the time period. Sites that may represent a transition to Basketmaker traditions: Upper Gunnison River basin About 8,000 to 3,000 years before present (roughly 6000 to 1000 BCE) inhabitants lived in dwellings and had storage systems similar to those of the Basketmaker II and San Pedro phase of the Cochise tradition. Yarmony House Two pit-houses dated about 6140 to 6410 years before present (about 4000 BCE) appear similar to Basketmaker pit-houses. One of the dwellings, set within a shallow basin, was in diameter with an antechamber, or front room. Within the home were a fire pit, slab-lined storage cists, animal bones, and metates and manos to grind wild food. The number of elk, deer, rabbit and other animal bones, and evidence that they were processed to extract bone marrow and grease, suggests that the site was used during the winter season or another period when food was scarce. The site is located in Eagle County, Colorado.
