Aubrey Cliffs, cliff in Coconino County, Arizona, United States of America
Aubrey Cliffs are a series of tall rock formations that rise about 1000 feet (300 meters) above Aubrey Valley and stretch along the edge of the Coconino Plateau. The cliffs are made of layered rock and extend northward from near Route 66 toward the Colorado River.
The cliffs formed millions of years ago through tectonic movement along the Toroweap Fault, which pushed rock upward and created the steep walls seen today. Native peoples inhabited the region for thousands of years and knew the landscape intimately.
The cliffs hold importance for the Navajo and Hualapai tribes whose lands border and overlap in this region. These rock formations are woven into the identity and history of the communities who have inhabited these territories for generations.
Access is best from Route 66 near Seligman, from where the cliffs are visible extending northward. The area is dry and open, so bring water and sun protection when spending time exploring near the formations.
A planned Navajo Nation wind farm project could generate electricity using turbines on the southern cliffs with a capacity of about 85 megawatts. This development represents how the community looks to harness the region's natural forces for contemporary energy needs.
