The Far View area was once an extensive farming community and one of the most densely populated regions of the Mesa Verde. This mesa top community includes Far View House, Pipe Shrine House, Coyote Village, Far View Reservoir (currently dry), Megalithic House, and Far View Tower. In ancient times, it was a place of modest homes interspersed with small farm fields. It was a place filled with people, vibrant life, and constant change. 

Beginning around 800 CE, Ancestral Pueblo people lived here for several centuries, farming the deep mesa-top soils, building their homes, and raising their families. This was not always a quiet woodland. On a summer day in 1050 this ancient community would have been filled with the smell of juniper smoke and the sounds of everyday life: conversations between people working together, barking dogs, laughing children, ravens calling overhead, and the wind rustling through the shiny corn leaves. In the mid-1100s, there may have been at least 35 occupied villages and surrounding farm and garden plots within a half-square-mile area, including those you can visit today.
