Sunset Crater Volcano, Flagstaff
The colorful cinder cones were formed by series of eruptions between 1040 and 1100. A final eruption made the originally black upper portion of the cone to dusky red-orange patches, giving its name.

Lava Flow Trail
Hiking is prohibited to the top of the crater because of its continued erosion, but the visitors can still explore the Lava Flow Trail, a self-guided loop walk through the hardened lava flows and cinder fields at the base of Sunset Crater.

The Bonito Lava Flow is a basaltic flow, which means the lava is jagged or sharp.

Splotches of greens and yellows on the surface
These splotches are actually lichen. Lichen are part fungus and part plant (an algae) living together to function as a single organism.

Amidst the hardened lava varieties of wildflower, shrubs and trees spout up.
