Bears Ears: A story 11,000 years in the making

Historian Andrew Gulliford likens Bears Ears to a giant, outdoor history museum. The national monument is just 30 miles west of the Colorado-Utah border. Gulliford, who teaches at Fort Lewis College in Durango, has spent decades exploring the area's canyons, mesas, and desert expanses. His new book is "Bears Ears: Landscape of Refuge and Resistance."
