At first glance the desert can seem like a barren desolate place, void of life and beauty. But upon closer inspection it often reveals itself as a delicate world of endless variety and complexity, especially in the spring after a good winter like the one we’re having now.

This image of a natural garden in Plum Canyon in Anza-Borrego Desert State Park was taken with a Nikkor 180mm lens to isolate the scene and emphasize the colors of the cholla and wildflowers. The late afternoon backlight completed the picture by accentuating the detail of the cactus needles and setting them apart from the other elements as if to say, “look, but don’t touch”.

Exploring the balance between these contrasting worlds of beauty and danger is what makes the desert so fascinating. Visually it’s not as accessable as an alpine meadow or tropical rain forest, but for those willing to take a closer look the rewards are often just as great.

The Northern Elephant Seal, or sea elephant, ranges from the Pacific coastal waters of Canada to the tip of Baja, Mexico. It is the largest of the fin-footed mammals and with males typically weighing up to 6000 lbs it exceeds the walrus in size. Though they were hunted to the brink of extinction toward the end of the nineteenth century, their numbers have steadily increased in recent years due to protection from both the US and Mexican governments.

Elephant seals feed on fish and squid or other cephalopods and spend upwards of 80 percent of their lives in the ocean. They can hold their breath for nearly two hours and dive as deep as 2,000 feet in search of food. During the three month breeding season, bulls fight to establish territories along beaches and to acquire harems of up to 40 cows. This female is part of a large rookery at one of several pocket beaches near San Simeon, California.

Chaos is a term often used these days to describe our lives or our economy, but it’s also a natural concept that describes the non-linear ways in which nature moves. Chaos theory has its origins in the 1960’s when meteorologists first studied weather patterns and determined that the smallest factors could dramatically change the outcome. Edward Lorenz discovered that something as subtle as a butterfly’s wings could create an extreme variation in weather simulations, which became known as “the butterfly effect” and explains why it’s impossible to predict the weather with 100% accuracy.

Examples of chaos theory in nature include the movement of the ocean and wind, the escape pattern of an animal, water flowing down a river, and climate changes. They all have unpredictable but logical results, which means that we won’t know exactly what’s going to happen next but it will make sense when it does. From a photographic standpoint chaos often creates a wonderful palette of  form and color that leaves us with a sense of awe at the natural world around us.

HDR (or High Dynamic Range) is an increasingly popular process of combining digital files to create an image that more closely resembles what the eye sees. It’s used primarily when the contrast in a scene exceeds the latitude of what the film or sensor is able to capture in a single shot.

Depending on the amount of contrast in the scene a series of up to 7 identical brackets one stop apart are combined, which represent all of the tonal value from the darkest shadows to the brightest highlights. This image of False Kiva in Canyonlands National Park is very close to what I saw that evening, but the extreme contrast would have made it nothing more than a vision in my mind’s eye if not for HDR.

Photographic purists may balk at the use of such digital wizardry, but in fact it is not unlike the dodging and burning that Ansel Adams used countless times in the darkroom to achieve his magical prints. As he put it, “the negative is the score, and the print is the performance”. I concur, and feel that any photographic process which helps render a natural scene as it was witnessed is acceptable as long as it does not deceive the viewer or alter the truth.

Backcountry skiing opens up a whole new world of travel, sport and photographic possibilities. Locations in the Sierra Nevada Mountains, which are often crowded and require permits long in advance during the rest of the year, are quiet and pristine during the winter months. Temperatures can drop to -20 degrees Fahrenheit so proper equipment is a must, but the reward is experiencing your own private ski bowls and perfect mountain landscapes.

This image was made at Treasure Lakes under Mount Abbott in the Rock Creek basin, one of the highest concentrations of 14,000 foot peaks in the Sierra. A 24mm lens filled the frame with the majestic peaks giving the skier a sense of place, while the Li-Ion batteries and compact flash cards performed flawlessly in the cold temperatures - a far cry from the old days of brittle film and fading button cells.

The Monterey Bay National Marine Sanctuary, which stretches from San Francisco to Cambria California, is the largest preserve in the nation and one of the richest marine environments in the world. Migrating grey whales, sea otters and elephant seals are just some of the protected wildlife that can be experienced along this magnificent stretch of coastline.

This image was made at Sand Dollar Beach on the Big Sur coast in Los Padres National Forest. It is one of the most rugged and scenic areas on the Pacific and a favorite location for photographers, surfers and beach combers alike.  A 17mm wide angle lens was used to frame the half-mile cove and Santa Lucia Mountains beyond, and a split neutral density filter balanced the exposure between the sunset and flowers.

The cliff dwellings of the American southwest are the most spectacular ruins north of Mexico. The Anasazi Indians (or ”ancient ones” as the modern Navajo call them) were the prehistoric pueblo culture that thrived in the Four Corners region between 900 and 1200 A.D. then mysteriously disappeared.

Many of their elaborate structures are well-preserved in national parks such as Mesa Verde in southwestern Colorado, Chaco Canyon in New Mexico, and Canyon de Chelly in Arizona. From three story citadels perched precariously on canyon ledges like Square Tower House above, to the 500 room Great Houses of Chaco Canyon, these skilled masons left a legacy to rival the ruins of ancient Greece.

Archaeologists and scholars still debate what caused their sudden demise toward the end of the 12th century, but the stone handywork of the Anasazi remains a fascinating testament to the vision and tenacity of these ancient people.

One of the more curious natural phenomena is the occasional tendency for nature to mimic human form. Anthropomorphic images (meaning human characteristics in inanimate objects) can appear in rocks, plants and animals. Typically they appear only for a fleeting moment or from a unique perspective, but like finding an Easter egg they are a photographic treat.

This image of Lady in a Bathtub Butte in Valley of the Gods, Utah was taken late in the day to create a strong silhouette and emphasize the outline of the rock against the blue sky. The back-lit clouds added a nice balance to the whimsical scene.

Shooting water in all its endless variety is one of the creative pleasures of nature photography. From drops of dew reflecting a crisp autumn morning to the power of cascading falls frozen in time, the camera allows many unique perspectives of our most abundant resource that are seldom seen in a passing glance.

This image of Calf Creek Falls in the Grand Staircase-Escalante National Monument was made on an overcast day with a long exposure of 20 seconds. The cloudy sky diffused the harsh mid-day light and saturated the colors of the mossy rock, while the slow shutter speed gave the falls a silky look.

A recent article in the Washington Post illustrated an interesting trend that is occurring in the medical profession these days and perhaps the timing couldn’t be better. Just when health insurance is the hot topic, doctors across the country are increasingly telling their patients to “take a hike” to fix what ails them.

No, they’re not trying to lose customers, but instead are medicating their patients with nature to treat everything from heart disease to attention deficit disorder. Detailed prescriptions are often written to include park or preserve locations,  specific trails and mileage. In many ways, as Ken Burns recently pointed out, our national park system can and should be an integral part of our health care system.

As a nature photographer, I spend a great deal of time on and off the trail and I feel fortunate that my work not only helps to protect these special places, but promotes my health in the process.
