The Sopris phase (AD 1000-1250) is a Late Ceramic period hunter-gatherer culture of the Upper Purgatoire, also known as the Upper Purgatoire complex. It was first discovered in the southern Colorado, near the present town of Trinidad, Colorado. The Sopris phase appeared to be greatly influenced by Puebloan people, such as the Taos Pueblo and Pecos Pueblo, and through trade in the Upper Rio Grande area.^[1]^[2]
