9. Bisti/De-Na-Zin Wilderness (New Mexico, USA)
Derived from the Navajo language, the name “Bisti” (pronounced Bis-tie) means “among the adobe formations,” while “De-Na-Zin” (deh-nah-zin) translates to “cranes,” or “standing crane.” These names reflect the unique terrain of the area as well as its cultural value to the Navajo people who have lived there for millennia.
About 70 million years ago, in the Late Cretaceous period, the Bisti/De-Na-Zin Wilderness’s geological narrative starts. At that time, much of what is now the southwestern United States was covered by an ancient coastline running along a shallow sea. This coastal habitat accumulated layers of sand, mud, and organic debris from rotting plants and animals over millions of years.
These sedimentary layers came into contact with the elements as the sea withdrew and the ground raised. The hostile desert environment, marked by wind, erratic but strong precipitation, and dramatic temperature swings, started the process of erosion that would eventually define the wilderness as it exists now. The strange and lovely forms we see today came from the softer layers erasing more quickly than the harder ones.
The Bisti/De-Na-Zin Wilderness’s hoodoos, tall, slender spires of rock rising from the bottom of desert basins, define it most clearly. Often topped with tougher, more durable crowns, these hoodoos range in form and size, some looking like mushrooms, others like alien beings or abstract sculptures. With each layer reflecting a different time of deposition, the vivid record of the geological history of the area is preserved in these formations.
Apart from the hoodoos, the wilderness region boasts a range of other amazing geological structures. These include badlands, areas of soft sedimentary rock and clay that have been greatly eroded by wind and water; clinker, a natural glass created when underground coal seams catch fire and bake the surrounding rock; and petrified wood, the remains of ancient forests turned to stone by mineral replacement.
Additionally well-known for its paleontological value is the Bisti/De-Na-Zin Wilderness. Dinosaur bones, eggs, and tracks among other significant fossil finds have come from the area. Among the most important discoveries was the almost whole skeleton of the tyrannosauroid dinosaur known as the Bisti Beast (Bistahieversor sealeyi), which lived some 74 million years ago. These fossils offer important new perspectives on the Late Cretaceous environment that prevailed here.
One of a kind experience that calls for careful planning is exploring the Bisti/De-Na-Zin Wilderness. There are no well defined paths, amenities, or water supplies in the isolated and undeveloped area. Visitors have to be self-dependent and ready for the demanding desert surroundings. For those who travel into this foreign terrain, the benefits are great nonetheless. The dynamic panorama of colours and forms created by the always moving play of light and shadow across the unusual rock formations seems to defy reality.
Photographers, who come to capture the unearthly beauty of the terrain, especially love the wilderness region. Sunrise and sunset when the low angle of the sun enhances the patterns and colours of the rocks makes the formations extremely breathtaking.
While allowing reasonable public access, conservation initiatives in the Bisti/De-Na-Zin Wilderness concentrate on maintaining its distinctive geological features and paleontological treasures. Declared a wilderness in 1984, the area boasts the best degree of protection accessible for public land in the United States.
Geologists, palaeontologists, and ecologists find a living lab in the Bisti/De-Na-Zin Wilderness. Its exposed rock strata and well-preserved fossils offer important details on ancient ecosystems and the evolution of life on Earth. The area also provides understanding of erosion’s mechanisms and long-term consequences of climate change on arid environments.
Though it seems almost impossible, visitors are taken to a realm that is very much a part of the rich geological legacy of our planet as they meander throughout this dreamscape. The Bisti/De-Na-Zin Wilderness provides evidence of the great variety of Earth’s terrain and the ability of natural forces to produce sceneries of amazing beauty and scientific value.
