Sunset Crater Volcano National Monument

Located north of Flagstaff near the Wupatki National Monument, this volcano last erupted a little before the Norman Conquest on the other side of the world in 1066. The volcanic eruption scattered ash and black cinder for miles around the area. Serendipitously, the ashen soil allowed subsequent tribes to inhabit the area due to its ability to retain water. Alongside the volcano, visitors can examine fascinating geologic features such as 'Squeeze-ups' and 'Hornitos,' which are bulbous mounds of lava and droplets. Hike along the one-mile Lava Flow Trail and discover hidden wonders or climb a nearby cinder cone on the Lennox Crater Trail and enjoy the astounding views. Unfortunately, hiking to the top is prohibited.
