Summary
DescriptionKasha-Katuwe Tent Rocks NM (9406466737).jpg | The Kasha-Katuwe Tent Rocks National Monument in New Mexico is a remarkable outdoor laboratory, offering an opportunity to observe, study, and experience the geologic processes that shape natural landscapes. The national monument, on the Pajarito Plateau in north-central New Mexico, 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.” In close inspections of the arroyos, visitors will discover small, rounded, translucent obsidian (volcanic glass) fragments created by rapid cooling. Please leave these fragments for others to enjoy. The complex landscape and spectacular geologic scenery of the national monument has been a focal point for visitors for centuries. Before nearby Cochiti Reservoir was built, surveys recorded numerous archaeological sites reflecting human occupations spanning 4,000 years. During the 14th and 15th centuries, several large ancestral pueblos were established and their descendants, the Pueblo de Cochiti, still inhabit the surrounding area. Kasha-Katuwe means “white cliffs” in the traditional Keresan language of the Pueblo.
