The silence of nature is very real.
It surrounds you, you can feel it.
A couple of hours east of Bosque is another naturalist and photographer destination – White Sands National Monument. The original plan was to drive down one afternoon, hike the dunes at sunset, spend the night in the nearby town of Alamogordo, and then return at sunrise to photograph the dunes in morning light. That plan came apart when the chosen morning date was accompanied by one of the periodic closings of the monument due to missile tests at the adjacent White Sands Missile Range. So, only one afternoon was spent away from the birds at Bosque, but what an afternoon it was.
On the drive to Alamogordo you pass through miles of high desert bounded by mountains. The landscape changes little until suddenly you pass through what looks like a charred moonscape known as the Valley of Fires. Highway 380 cuts across a huge lava flow four to six miles wide, 160 feet thick and covering 125 square miles. The lava flow dates back about 5,000 years and is considered to be one of the youngest lava flows in the continental United States.
Walk cautiously out onto the flow and you can see the structure of the lava which includes many features that are more often seen in fresh Hawaiian lava flows. One of the most apparent is the pahoehoe texture of the surface of the flow. The texture forms when the surface of the flowing lava begins to cool, and the underlying, hotter lava is still flowing. The cooler surface is dragged along by the flowing lava underneath, and forms the wrinkled or coiled rope appearance.
After passing through more desert (oddly sprinkled with some groves of Pecan and Pistachio trees) you arrive at White Sands National Monument. From the Visitor Center, the view reminded me of the tallest sand dune on the East Coast, North Carolina’s Jockey’s Ridge, only with mountains in the background instead of a sound or ocean. But when I drove through the auto loop, it became apparent that this place was Jockey’s Ridge on steroids. And instead of the tan sands I am accustomed to, these sands are snow white.
The dunes at White Sands are derived from gypsum-bearing marine deposits laid down in a shallow sea over two hundred million years ago. With the subsequent rise and fall of the surrounding region, the present day Tularosa Basin was created, nestled between the San Andres and Sacramento mountain ranges. Since no rivers drain the basin, runoff from the surrounding mountains, laden with gypsum and other sediments, is trapped in the basin. This water then pools in low spots, often forming huge shallow lakes. When that water evaporates in the windy, dry environment, it deposits gypsum in the form of selenite crystals, which eventually break down from weathering into sand-sized particles. The white sands can now be moved by the winds and shaped into the dunes that cover 275 miles of desert, creating the largest gypsum dune field in the world.
A hike in the dunes is eye opening and ear challenging. Without the birds of Bosque, the scene is eerily quiet. A Kit Fox had left tracks across one dune face and that, along with two beetles, were the only signs of animal life in the dunes other than scattered human and dog tracks. You take to heart the signs warning you to be cautious, have enough water, and to not get disoriented in the vastness of the dunes.
As the sun sinks toward the mountains ringing the horizon, the light changes and the dunes begin to transform. Their delicate hidden details begin to emerge, outlined by artistic shadows thrown by the low angle light.
Everywhere you look, the sand is a rapidly changing palette. I see how people can get lost – the tension of the desire to walk over to that dune ridge for a photo fights the desire to find a sure route back through the dunes to a vehicle…a dune dilemma for sure. But since the gate closes promptly at 6 pm this time of year, the choice becomes clear at last and I seek the direction of the car.
But on the drive out, the light intensifies and a new dimension is added to the landscape – plants clinging at the edge of the dune field. Who could resist? Just a few more images…
