Sunset Crater Volcano National Monument
Sunset Crater Volcano National Monument preserves the dramatic landscape formed by the eruption of Sunset Crater in 1064 CE, the most recent volcanic eruption in Arizona. Visitors experience a unique wonderland of volcanic features, including cinder cones, lava flows, and rejuvenating plant life that tells a story of destruction and rebirth over the last millennium. The monument is located just north of Flagstaff, Arizona, along US Highway 89.

Explore the legacy of Arizona’s youngest volcano, hike through volcanic landscapes, and discover how fire and eruption have shaped the land and lives in this remarkable national monument.

Overview

Sunset Crater Volcano National Monument was established to protect and interpret the site of the dramatic eruption that forever altered the northern Arizona landscape. The eruption began in 1064 CE (some sources say 1066), creating a 1,000-acre lava flow, forming cinder cones—including Sunset Crater itself—and depositing ash over a wide area.
The eruption impacted the lives of indigenous peoples and altered ecosystems, but over time, nature has reclaimed much of the area, with new plant growth and wildlife adapting to the volcanic terrain. The monument preserves this living laboratory of volcanic activity and ecological succession.

Geology and Ecology

Sunset Crater’s eruption reshaped the land in a matter of months, creating volcanic features that remain prominent today. The cinder cone, lava flows, and ash deposits provide a visual record of the eruption’s power.
Over the past 1,000 years, plants such as ponderosa pine, wildflowers, and grasses have recolonized the area, showing ecological succession in action. The monument is a living classroom for volcanic geology and the resilience of nature.

Cultural History

The eruption affected the indigenous peoples living in the region, including the ancestral Puebloans, who adapted to the changing landscape. Archaeological sites in the broader area, such as Wupatki and Wupatki National Monument, reflect the adaptation and resilience of these communities.

Management and Preservation

The monument is managed by the National Park Service to preserve volcanic features, plant and animal life, and cultural resources. Ranger-led programs and interpretive signage help visitors understand the significance of the eruption and the ongoing recovery of the landscape.
