Albuquerque Journal, "Archaeologists call on feds to protect Chaco Canyon area."

In a letter to Interior Secretary Sally Jewell, they talked about the countless hours they’ve spent in the field, the dozens of books they’ve published about the Chaco society and their decades of collective experience studying its connection to modern Native American tribes in the Southwest. They call Chaco a distinct resource.

“Many of the features associated with this landscape — the communications and road systems that once linked the canyon to great house sites located as far away as southeast Utah and which are still being identified to this day — have been damaged by the construction of oil and gas roads, pipelines and well pads,” the archaeologists said.
