Today’s trek was a deep dive into the high desert’s geological wonders. The journey began early with a rugged six-mile loop through the canyon floor, offering an up-close look at the massive Sipapu and Kachina bridges. After a midday recharge, the whole crew—Lori, Brian, and Ruby—made the hike down to the delicate Owachomo Bridge.
The Story of the Stone: How These Bridges Formed
Natural Bridges National Monument, established in 1908 as Utah’s first National Monument, protects three of the world’s largest natural stone bridges. Unlike arches, which are carved by wind and frost, these bridges were sculpted primarily by the force of moving water.
The Process: Over millions of years, meandering streams (Armstrong and White Canyons) cut deep into the Cedar Mesa Sandstone. During flash floods, the water hit the “necks” of these canyon bends with incredible force.
The Breakthrough: Eventually, the water bored through the solid rock, creating a shortcut. Once the stream broke through, it abandoned the old meander and began flowing directly under the new bridge, widening it over time through erosion and rockfalls.
Whispers of the Past: Horse Collar Ruins
The ancient masonry tucked into the cliffs provides a window into the lives of the Ancestral Puebloans who inhabited this area roughly 700 to 1,000 years ago.
The Ruins: These are among the best-preserved Ancestral Puebloan sites in the region. The name “Horse Collar” comes from the unique shape of the doorways on two of the granaries, which resemble horse collars.
The Lifestyle: The site features remains of dwellings and a kiva (a circular underground room used for spiritual ceremonies). These inhabitants were skilled dry-land farmers, growing corn, beans, and squash on the mesa tops before eventually migrating south toward the Rio Grande and Little Colorado River valleys.
A Colorful Canyon Local
The vibrant lizard captured in today’s photos is a Great Basin Collared Lizard. Known for the distinct black bands around its neck, these lizards are the “sprinters” of the desert. They are one of the few species that can run using only their hind legs when chasing down insects or even smaller lizards. Their bright turquoise and yellow hues are especially striking against the weathered driftwood and red sandstone.
Under the Canopy: A Night at the World’s First Dark Sky Park
What a way to end this busy day! After miles of dust and red rock, we capped off our visit to Natural Bridges National Monument with an experience that was truly out of this world.
We pulled into the visitor center after dark—around 9:00 PM—and the transformation was immediate. It’s easy to forget that this monument holds a massive title: back in 2007, it became the very first certified International Dark Sky Park in the world.
Why the Dark Matters
We attended a series of great presentations that really hit home. It’s not just about the view; it’s about survival. We learned how critical a truly dark sky is for:
Wildlife Navigation: From migrating birds to insects, the natural cycle of light and dark acts as a biological compass.
Human History: For millennia, humans used these same stars for navigation and storytelling—a connection we are rapidly losing to light pollution.
A Closer Look
The highlight of the evening was getting the opportunity to look through a professional telescope. Seeing the depth of the cosmos without the interference of city lights is something that stays with you. It’s a humbling reminder of our place in the universe.
It was a great evening and the perfect, quiet way to end a day of exploration. If you’re ever in this corner of the world, stay after the sun goes down. The real show is just beginning.
