Among the Cones: Exploring the Reopened Kasha-Katuwe Tent Rocks National Monument

Published on 16 May 2025 at 10:18

Discover a surreal landscape of cone-shaped rock formations, slot canyons, and ancient history at this newly accessible natural wonder near Santa Fe.

Southwest of Santa Fe, nestled on the Pajarito Plateau, lies one of New Mexico's most geologically fascinating and visually striking landscapes: Kasha-Katuwe Tent Rocks National Monument. After a period of closure, this remarkable outdoor laboratory has reopened, offering visitors a unique opportunity to observe the powerful forces that shape our planet, all while respecting the sacred ancestral lands of the Pueblo de Cochiti.

The story of Tent Rocks begins 6 to 7 million years ago with violent volcanic eruptions in the Jemez Volcanic Field. These cataclysmic events spewed massive quantities of pumice, ash, and tuff (consolidated volcanic ash) across the landscape, in some places depositing layers over 1,000 feet thick. Over millennia, wind and water went to work, carving into these deposits, creating narrow canyons and the iconic cone-shaped "tent rocks" or hoodoos that give the monument its name. Many of these formations are topped with harder, more resistant caprocks, which protect the softer pumice and tuff underneath, allowing the spires to form. These tent rocks vary in height, some soaring up to 90 feet. The name "Kasha-Katuwe" itself means "white cliffs" in the traditional Keresan language of the Pueblo de Cochiti, whose people have a deep ancestral connection to this land, considering it a significant and sacred place for millennia. Established as a National Monument by Presidential Proclamation in January 2001, it is co-managed by the U.S. Bureau of Land Management (BLM) and the Pueblo de Cochiti.

Why This Day Trip is a Must-See and Do

  • Unique Geological Formations: Witness the otherworldly landscape of towering conical rock formations, a photographer's and geologist's dream. The trails offer up-close views of these remarkable structures.
  • Slot Canyon Hiking: The Canyon Trail takes you through a narrow slot canyon, where you can often touch both walls simultaneously, offering a thrilling and intimate hiking experience.
  • Panoramic Views: The climb to the top of the mesa on the Canyon Trail (a 630-foot ascent) rewards hikers with breathtaking panoramic views of the tent rock formations, the Sangre de Cristo, Jemez, and Sandia Mountains, and the Rio Grande Valley.
  • Cave Loop Trail: For a less strenuous but equally interesting hike, the Cave Loop Trail (1.2 miles) winds past smaller tent rocks and a human-carved cavate (a small cave-like shelter) in the cliffside.
  • Birdwatching and Plant Identification: The monument provides habitat for various bird species, including swifts, swallows, kestrels, and hawks, often seen nesting high in the cliffs. Desert plants like manzanita, Indian paintbrush, and piñon-juniper woodlands dot the landscape.
  • A New, Managed Experience: Due to past issues with over-visitation, Kasha-Katuwe Tent Rocks now operates under a new managed access system. This includes a two-part reservation process:
    1. BLM Ticket Reservation: Must be obtained in advance via Recreation.gov. A limited number of passes are available each day. (America the Beautiful and other federal passes may waive the $5 BLM fee for the passholder and up to three guests, but a reservation is still required).
    2. Cochiti Pueblo Tribal Access Pass: Must be purchased separately from the Pueblo de Cochiti (e.g., via PurplePass.com, around $20 per adult, with fees for children; federal passes do not cover this).
    • Important Visitor Protocol: All visitors must first check in at the Cochiti Pueblo Visitor Center. From there, pilot vehicles escort visitors into the monument at scheduled times. The last entry is typically around 1:00 p.m., and all visitors must exit by 4:00 p.m. The monument is open Thursday through Monday, with specific holiday and seasonal closures (e.g., usually closed from mid-December to late January). Always check the official BLM and Pueblo de Cochiti websites for the very latest hours, fees, reservation details, and any unexpected closures before planning your visit.

Five Things Most People Don't Know

  1. Volcanic Violence Birthed Beauty: The soft rock that forms the tents is not sandstone but primarily tuff, pumice, and ash from incredibly explosive pyroclastic flows – incandescent avalanches of hot gas and rock fragments – originating from the Jemez Volcanic Field millions of years ago.
  2. Caprocks are Key: The distinctive cone shape of the tent rocks is due to harder, more erosion-resistant boulders (caprocks) that sit atop many of them. These caprocks protect the softer material directly beneath them, while the surrounding material erodes away. Once a caprock is gone, the tent rock erodes much more quickly.
  3. "Kasha-Katuwe" is an Ancient Name: The name Kasha-Katuwe, meaning "white cliffs" in the Keresan language, reflects the long-standing connection and significance of this landscape to the people of Cochiti Pueblo, long before it became a national monument.
  4. Apache Tears Can Be Found (But Not Taken!): Small, rounded obsidian (volcanic glass) nodules known as "Apache tears" can sometimes be found eroding out of the tuff deposits. These form when water hydrates the obsidian, creating a perlite shell around an obsidian core. Remember, collecting any rocks or natural features from the monument is prohibited.
  5. A Fragile, Co-Managed Treasure: The monument is a delicate ecosystem and a sacred cultural landscape. The new managed access system, co-developed by the BLM and the Pueblo de Cochiti, aims to protect these fragile resources and ensure a respectful and high-quality visitor experience, recognizing the Pueblo's deep ancestral ties and ongoing stewardship.

A visit to Kasha-Katuwe Tent Rocks National Monument is a journey into a uniquely sculpted world, offering awe-inspiring beauty and a chance to appreciate the profound forces of nature and the deep cultural heritage of the land. Be sure to plan well in advance to secure your reservations for this popular and now carefully managed destination.
