About the Kasha-Katuwe Tent Rocks National Monument

The Kasha-Katuwe Tent Rocks National Monument is a remarkable outdoor laboratory, offering an opportunity to observe, study, and experience the geologic processes that shape natural landscapes. The national monument is on the Pajarito Plateau in north-central New Mexico and includes a national recreation trail and ranges from 5,570 feet to 6,760 feet above sea level. The cone-shaped tent rock formations are the products of volcanic eruptions that occurred 6 to 7 million years ago and left pumice, ash and tuff deposits over 1,000 feet thick. Tremendous explosions from the Jemez volcanic field spewed pyroclasts (rock fragments), while searing hot gases blasted down slopes in an incandescent avalanche called a “pyroclastic flow.”
