The Southwest's desert wonderland is at last getting the attention it deserves. Hike, drive, enjoy it now
The Sonoran desert dawn announces its arrival with the sound of a thousand stirrings. It breaks a silence so complete that you might think nothing short of a sonic boom could dent it. Sure, coyotes howled during the night, their yips and yowls bouncing off the mountains and across the valley. Owls screeched and bats fluttered above our campsite in the Table Top Wilderness Area in south-central Arizona, about 20 miles off U.S. 8. But the silence of the night always closed back in, reinforcing the illusion of emptiness common to deserts. The rising sun, still beneath the horizon, begins to light the morning, gradually repainting the sky shade-by-shade and minute by minute: from gray to pink to violet on its way to a cloudless mid-day blue.
The breeze picks up almost imperceptively, cool at first then mixing with the warmth of the afternoon to come. A caress of a wind. It carries with it a hint of moisture from the light dew that settled, seemingly incongruously, over the desert during the night. The wind rustles the brittlebush and whispers its way though the clustered needles of saguaros, the hallmark cactus of the Sonoran Desert.
High on a 40-foot saguaro, a Gila woodpecker insistently calls as it flits about from branch to branch. White-winged doves coo, and a whiptail lizard scurries across the gravel. The spindly, 15-foot-tall branches of the ocotillo, bare and dead-looking things under dry conditions, are fully leafed out; bees and hummingbirds sip from the tubular red flowers that blossom at the tips. The sweet melodies of songbirds--curve-billed thrashers and native sparrows--play off the low buzz.
The morning surge lasts maybe an hour, but it stays with you much longer. Any notion of the Sonoran Desert as empty, a wasteland, is forever shattered in this first waking moment, to be replaced by an understanding that this is a kind of dryland Eden.
As David Yetman, a research social scientist at the University of Arizona's Southwest Center, describes these mornings, "There is no more glorious time or place in the world."
The desert different
The Sonoran Desert stretches some 120,000 square miles from its Arizona heartland into Southern California and Mexico. It includes not only well-known spots, such as Organ Pipe Cactus National Monument and Saguaro National Park, but also lesser-known areas on its fringes, like the Nature Conservancy's Ramsey Canyon Preserve, a wooded, watered enclave that hardly seems desertlike. In fact, while the saguaro is the dominant image, the desert actually consists of six distinct plant communities, from vast creosote seas to hidden palm canyons two hours outside of Los Angeles.
It is a rich environment. Half of North America's bird species, 500 in all, are found here. There are 130 mammal species, including the endangered Sonoran pronghorn and even scattered jaguars. There are 5,000 plants, including 3,500 native species. Look hard enough and you may find 20 amphibian and 30 fish species, in larger streams and tiny oases.
Yet the Sonoran Desert has been misunderstood. "When people go out to a desert, they normally start itemizing what is missing," says Tucson-based writer Charles Bowden. "What happens over time is they cease to think something is missing. There's no absence in the desert. It's the place where the clutter of life is removed and you can finally see."
To Bowden and many other desert denizens, the Sonoran Desert is a paradise--not a word usually used to describe deserts. Indeed, at certain times and in certain places, it can be one of Earth's harshest places. A single, careless misstep can lead to a long, agonizing afternoon of plucking cholla needles from your legs. There are scorpions, tarantulas, rattlesnakes, and the Gila monster, one of the two poisonous lizard species in the world. The other--the beaded lizard--also happens to live here.
Even with two separate rainy seasons (winter and the furious summer monsoons) that make the Sonoran Desert's upland areas the world's lushest desert, evaporation outpaces rainfall 10 to 1. Some sections can go years without rain, and springs are almost nonexistent. In places, the bones of travelers who tried to traverse this expanse more than a century ago may still be bleaching under a sun that has shone here almost every day since.
It seems a dangerous place, and sometimes it is. But as Bowden says: "Historically, we have a negative image of the desert that comes from the Bible itself. And we are creatures of water in an evolutionary sense. At first we have an unconscious discomfort with arid environments. We worry about becoming desiccated. But there are far more hospitable days in a year in the Sonoran Desert than there are in Yellowstone National Park."
A paradise threatened
Paradise, almost by definition, is a delicate place, and the Sonoran Desert is no exception. With Arizona's population at 5 million and growing, urbanization has encroached upon pristine areas around Phoenix and Tucson. As Arizonans turn to the desert for recreation, a careless minority scars the land by taking vehicles off-road. Others, ironically, traffic in saguaros and other cactus destined for new suburban gardens. The fragile biology is also threatened by invasive plant species, such as the aggressive African import buffelgrass, which pushes out native plants and increases fire danger.
The Sonoran Desert is uniquely vulnerable to such pressures. It does not recover quickly. To give some perspective on the desert's time frame, it takes a saguaro 10 years to grow its first 11/2 inches.
Nor is the complexity of the Sonoran Desert or the interaction of its species fully understood. When you stop and marvel at the burst of activity of a Sonoran dawn, you are also witnessing the intricate workings of an ecosystem in operation. At the Arizona-Sonora Desert Museum, researchers are looking at the migration patterns and other behavior of pollinators: the hummingbirds, bees, moths, and bats that plants such as saguaros depend on to spread their pollen and reproduce. It is a case of mutualism, says Rick Daley, the museum's executive director.
"If bats stop migrating, you don't have saguaros. If you don't have saguaros, all the other animals and plants that depend on them will disappear," he says. "These organisms are critical to the whole environment, but we hardly know anything about their real patterns."
A once-in-a-nation opportunity
In the face of development pressures, there are growing grassroots and government attempts to provide the Sonoran Desert with additional protections. Pima County's Sonoran Desert Conservation Plan seeks to balance development with habitat protection for such creatures as the endangered ferruginous pygmy-owl. More ambitious is a citizen proposal to create a 5,000-square-mile Sonoran Desert National Park. The park would include such existing federal lands as Organ Pipe Cactus National Monument, Cabeza Prieta National Wildlife Refuge, and the Barry M. Goldwater Air Force Range. More than 1.1 million acres of these parcels are already dedicated wilderness. Combined with the Pinacate Biosphere Reserve in Mexico, such a national park would create an ecological preserve of global significance.
Bowden and his longtime hiking buddy, author Bill Broyles, have been instrumental in creating the proposal. Bowden says that for all the development pressures on the Sonoran Desert, there is still plenty left to save. "It's not just a once-in-a-lifetime opportunity. It's a once-in-a-nation opportunity," says Bowden.
The Sonoran Desert National Park wouldn't be a national park in the classic sense. With its 360° perspectives and foreboding expanses, this desert doesn't lend itself to easy postcard tourism. Still the ephemeral display of its full wildflower glory--those rare times when poppies, lupines, and owl-clover spread a blanket of golds and purples across the land--is as spectacular as anything to be found in the national park system.
An important part of the Sonoran Desert experience is its vastness and the knowledge that a place so unspoiled still exists. Humans have long sought the mystical in the desert, and it is still to be found here, both 100 miles from nowhere and even on a driving loop in Organ Pipe Cactus National Monument.
We found it among the saguaros and palo verdes of the Table Top Wilderness Area--in the middle of nothing and at the center of everything.
"Whenever I'm out in the Sonoran, at first I'm overwhelmed by its immensity," says Bowden. "By the time I leave, I'm chilled that it's too small. Its sense of peace should be available everywhere. At first the idea that there's not going to be a human for another 40 miles is frightening. Then it becomes the greatest comfort in your life."
Prime season in the Sonoran Desert is November through April, depending on elevation. Winter temperatures can be cooler than you might expect, with January daytime temperatures averaging in the mid- to upper 60s; higher elevations can get snow.
The desert is known for its wildflower bloom; perennials and annuals usually peak between mid-February and mid-April. The Desert Botanical Garden's wildflower hotline (480/481-8134) is frequently updated in season.
If you can brave the heat, late spring and summer offer blooming cactus and the dramatic monsoon rains.
An indispensable guide for any desert visitor is A Natural History of the Sonoran Desert (Arizona-Sonora Desert Museum Press and University of California Press, 2000; $24.95; 520/883-3028). It offers a complete look at Sonoran Desert ecology, with details on individual species and essays that bring the desert alive.
