This aerial view shows the wetlands of the Cienega de Santa Clara, 40,000 acres of vegetation and wildlife habitat in Mexico's Sonoran Desert that have been revived with waste water from the Yuma Desalination Plant. The Colorado River winds through several national parks and numerous canyons, including the Nankoweap Canyon in Arizona. A few river miles upstream from where the Colorado River currently runs dry, the channel meanders between levees just below the Morelos Dam, surrounded by irrigated agriculture. Our green lawns, golf courses, swimming pools, and generally thirsty cities also take a share of the dwindling water, as do reservoirs, where 15 percent of the basin's water evaporates into thin air each year.
Although people tend to think of the Colorado as a single channel that slices through the Grand Canyon, the river system is really made up of scores of major tributaries that are collectively known as the Colorado River Basin. The Colorado River is both servant and scenic wonder to the 36 million Americans it supplies with water. It is now widely accepted that population growth and climate change will cause ever more intense water shortages in the West, much like the travails of Egypt over the long-disputed Nile.
Despite all this change, the massive Colorado River Delta, bearded with salt grass, is still one of the most wild and beautiful places betwixt source and sea: lush with unexpected groundwater in its center and surprisingly alive with rattling kingfishers, circling mallards, probing cattle egrets, mischievous ravens, prowling ospreys, and snakelike cormorants diving for fish. It took me five months to paddle there, 1,450 miles (2,330 kilometers) from the Continental Divide, plunging as much as 90 feet (27 meters) per vertical mile through bone-breaking rapids, then spilling out into reservoired calms that stretch for more than 300 miles (480 kilometers) of its path toward Mexico's Sea of Cortez. In the four years since that journey, I've continued my exploration of the Colorado River Basin's tributaries.
My primary tool is a camera, along with old landscape photographs that show these waterways in an earlier, "PreDambrian" statea€”the term ecologically astute boatmen use to longingly refer to an era before nearly 100 dams were built, dams that now stop sediment flow and unnaturally refrigerate river temperatures.
The Grand Canyon's crux rapid, Lava, drops 37 feet (11 meters) in less than 100 yards and routinely flips the two-ton rafts of the best boatmen. The Green River, the largest of the Colorado's tributaries, once flushed half of an ocean liner's worth of sediment 730 miles (1,175 kilometers) every day through Wyoming and Utah, briefly draining western Colorado before reaching its Utah confluence with the Colorado River. To demonstrate these effects I scour archives, from the National Archives in Maryland to the Bancroft Library in California, and when I find a compelling black-and-white image of a pristine river within the region, I seek out the original photographer's bankside camera stations and take a new photo. Although I usually find my photographic quarry, in many instances the scenes are so overgrown with towering invasive plants that I can't see, let alone photograph, the river. Discovering their historic camera stations and unveiling radically changed riverscapes always makes me feel like I have unearthed buried anti-treasure, revealing the secret, hidden costs of Western reclamation.
In this post-DamNation, one of many restoration projects targets ancient fish that still swim in the basin's waters. The beauty of these fish is in their uncanny adaptation to a bygone eraa€”a trait not seen in their newly introduced trout and bass predators. Highways crisscross the desert in Phoenix, Arizona, where population growth has put a major strain on resources. Downtown Las Vegas struggles with the need to balance water consumption with tourism and a growing population. Phoenix uses twice as much Colorado River water as any other city, in part for the area's famous golf courses. Like these fish hidden beneath the water, human-caused alterations on the surface are complex, and my image pairs don't always show the ill effects or root causes of the river basin's transformations. Although forecasting how changing climate will affect water within the basin is an imprecise science, scientists expect the region to get hotter and drier. The Bureau of Reclamation also recently released a study predicting that by 2060, the Colorado River's flows will decline by 8.7 percent. As for the lingering drought that began in October 1999: Historically, droughts are a part of normal climatic variations, yet tree-ring records show only three longer droughts in the basin within the past 1,300 years. Studying my then-and-now image pairs for signs of a changing climate, I find evidence of recent forest fires, loss of river flow, and natural and unnatural geomorphologic changes such as destruction of meanders and disappearance of sandbanks.
From 1990 to 2008, the number of people relying in part on Colorado River Basin water grew by ten million. We eat the river in cheese and beef and vegetables, products that are made with water from the Colorado and then shipped all over the world.
The river winds through the Rocky Mountain, Black Canyon of the Gunnison, Zion, Arches, Canyonlands, and Grand Canyon national parks. Let's face it, the river is the beating heart of life itself, and when ita€”the Colorado, the Green, the San Juan, the Gunnisona€”no longer runs, the Southwest will become as dried out as old toast. Jonathan Waterman treks across the dry Colorado River Delta, which was once thriving with life and an indigenous culture. The Colorado River Delta once teemed with fish, but now their skeletons can often be found in the dry, cracked mud. Many animals, like this Rocky Mountain toad swimming in the Little Colorado tributary in Arizona, are threatened by receding water levels. And water use by the Colorado River's outlying farmlands, such as those in the Imperial Valley near the Mexican border, could be halved if farmers irrigated their crops with pipes underneath the soila€”as in Egypt, which is experimenting with saving Nile water through the use of drip irrigation near the Sudanese border.
For all the good ideas yet to be initiated, there are as many energy-intensive proposalsa€”such as canaling Green River water over 500 miles (800 kilometers) from Wyoming to Colorado, building desalination plants, or laying pipelines from the Missouri Rivera€”that would only accelerate the effects of the original reclamation engineering and increase the greenhouse gases that helped create today's dilemmas. To reverse the ominous trend of southwestern water wastefulness and river destruction, we need more good news like this: In November 2012, the so-called "Minute 319" was added to the 1944 International Treaty on the river. Although one percent is not a lot of water, it will simulate the seasonal floods of old and keep the riverbed wet. In time, if we follow this example of budding restoration, we'll have the opportunity to revive dozens of other western rivers. While I was paddling from source to sea, a week's journey below the Continental Divide, in a terrific wind near Kremmling, Colorado, I had an encounter that encapsulated the work we need to do for the river.
Water from the Colorado River Basin meets at least some of the residential and commercial needs of tens of millions of people, over two-thirds of whom dona€™t live inside the basin. Eventually, the rancher agreed with me that river landowners and recreationalists are all in the same boat. An exhibition of 75 iconic images of the American West spanning more than a century will open October 27, 2012, at the National Museum of Wildlife Art in Jackson Hole and at nine other museums across the U.S.
A presentation by photographer William Albert Allard, a major force at National Geographic for 50 years, will mark the opening of “National Geographic Greatest Photographs of the American West” at the National Museum of Wildlife Art in Jackson Hole, Wyo. American documentary photographer William Albert Allard, who began his career as an intern at National Geographic in 1964, is one of the few photographers of his generation whose entire professional body of work is in color. Company Information: A member of the Museums West consortium and accredited by the American Association of Museums, the museum, officially designated the National Museum of Wildlife Art of the United States by an act of Congress in 2008, provides an exciting calendar of exhibitions from its permanent collection and changing exhibitions from around the globe.

The Pacific laps at rocky bluffs that lead up to the giant trees of Redwood National Park in California. It's no secret that interracial relationships are trending upward, and in a matter of years we'll have Tindered, OKCupid-ed and otherwise sexed ourselves into one giant amalgamated mega-race.
This is certainly encouraging, but there are obvious flaws with tracking racial population growth through a survey that lets people self-identify, especially since so many familial, cultural and even geographical factors influence your decision to claim one or multiple races. The Wall Street Journal reported a few years back that 15% of new marriages in 2010 were between individuals of different races. The future: As for how this looks moving forward, studies have repeatedly shown that young people, especially those under 30, are significantly more amenable to interracial relationships than older adults, while college grads are more likely to have positive attitudes toward them than those with only a high school diploma. But in the meantime, let us applaud these growing rates of intermixing for what they are: An encouraging symbol of a rapidly changing America. Denali's singular 92-mile (148-kilometer) road leads visitors through its majestic valleys toward the towering Denali, the crown jewel of the park. Climbing Denali, North America’s highest peak, is a daunting task for even the most experienced mountaineers at Denali National Park in Alaska. Other North American parks have their wildlife, but none has animals so visible or diverse as Denali. Many Denali-bound travelers use the Alaska Railroad, which drops visitors off at the entrance to the park.
Grizzly bears are easily identifiable by their distinctive shoulder humps and long-clawed front paws. Winter visitors to Denali National Park are sometimes treated to a viewing of the aurora borealis, or northern lights, seen here beaming down above the Chugach Mountains south of the park. Nimble-footed and fearless, Dall sheep, the world's only species of wild white sheep, cling to upper ridges and steep slopes throughout Denali. Nile crocodiles are the largest crocodilians in Africa, sometimes reaching 20 feet (6 meters) long. Critically endangered, the prehistoric-looking American crocodile struggles to survive in pockets of shrinking habitat.
The largest crocodilians on Earth, saltwater crocs, or "salties," are excellent swimmers and have often been spotted far out at sea. American alligators are found in freshwater coastal wetlands across the southeastern United States, from Louisiana to the Carolinas. Mother Nile crocodiles lay their eggs in a buried nest, opening it when high-pitched squeaks are heard from within.
The 80-mile (129-kilometer) canal is part of an extensive system of waterways that taps the Colorado River to irrigate hundreds of thousands of acres of farmland in southeastern California and southwestern Arizona.
Known as the limitrophe, this section of the upper delta functions as the political boundary between the U.S. Running as red and warm as fish blood, or as emerald and cold as a glacial lake, its 242,000-square-mile (626,777-square-kilometer) drainage area alternates between the primeval and the altered.
It is also one of the siltiest, most litigated over, and frequently paddled rivers in the world.
I know this because I've slept on the delta's muddy yet cracked, salt-stained sand, which washed down from the Grand Canyon. My mission is to showcase the breadth and beauty of this river system, as well as investigate the changes of the last century. Yet 195 miles (314 kilometers) upstream, unbeknownst to most of the two million annual visitors staring down at what they think of as the national park's violent central artery, the Colorado River is unnaturally controlled by the Glen Canyon Dam, standing 710 feet (216 meters) high. The particulate-carrying force of the Colorado River and its sandy tributaries then doubleda€”to an estimated six trillion pounds of silt per daya€”as it raced another 1,000 miles (1,600 kilometers) to the sea, building backwaters and sustaining flora and fauna with life-giving minerals.
This work of "repeat photography" is akin to a treasure hunt: whole days of paddling, walking, or driving while trying to line up riverbanks with distant mountains just as they were aligned in the old photosa€”which were often captioned before modern towns and river place-names existed.
Four of these warm-water, silt-adapted speciesa€”the pike minnow, the humpback chub, the bonytail chub, and the razorback suckera€”are now endangered because the silt- and migration-blocking dams also refrigerate the water temperature by dropping cold, mid-level (instead of warm, surface) reservoir water into the rivers below.
In the PreDambrian, pike minnows ranged over 1,000 miles (1,600 kilometers) of river and grew to 5 feet (1.5 meters), but they are now as stunted in range as they are in growth. If caught by fishermen they have to be immediately released, and they're passed by in favor of the more palatable, non-native sport fish.
Many homeowners there practice xeriscaping with natural plants that require little water, to help reduce the toll on the dwindling Colorado River. A study by the Department of the Interior's Bureau of Reclamation (the federal agency that manages the Colorado River) in August 2013 projected that the water in Lake Mead will decline to 1,060 feet (323 meters) by July 2015, which would likely result in water shortages being declared for 2016. That's equal to the amount of water canaled to Los Angeles, which gets half of its water from this river. I also see the growth of invasive and water-consumptive plant species like tamarisk and Russian olive, along with an incredible greening of river valleys that were barren in the 19th century. Many of us use it in our showers and pools, and in the fountains and green parks that our children play in. It is our wallets: a collective $26 billion per year from the recreation economy, and 250,000 sustainable jobs. We wear it (as cotton and flax) and condition the air with it, while creating energy with it and growing gardens with it and drinking it in cities far from its banksa€”such as Los Angeles, San Diego, Denver, and Phoenix. Conservationa€”large-scale xeriscaping (switching to landscaping plants that don't need much water), irrigation reform, a more watchful eye on the consumptive water-energy nexus, and discretionary crop plantinga€”can send a lot of water back to the rivers where it belongs. The agreement says that over a five-year trial period, a total of one percent of the historic flows will be sent south to the Colorado River Delta to rejuvenate native flora and fauna and, hopefully, to reach the sea.
A 2011 Pacific Institute study, the most up-to-date survey of the top 100 cities and agencies consuming basin water, showed that such non-agricultural water deliveries increased by 640,000 acre-feet from 1990 to 2008 in those cities. It was an uncommon event, but with distant water users seeking more diversions, ranchersa€”along with fishermen, boaters, and myriad other downstream usersa€”watch the river go "bony" each fall.
More than 36 million of us depend on this ancient river, although it's used and undoubtedly adored by millions more.
In 2010 National Geographic published his book Running Dry: A Journey From Source to Sea Down the Colorado River.
The exhibition will be on display at the National Museum of Wildlife Art through April 28, 2013. The park is home to several large lakes and miles of stretching Shelikof Strait coastline.
The river winds south along the Texas-Mexico border, passing through three major canyons and lush floodplains within the park on its way to the Gulf of Mexico.

According to legend, it is here where the demigod Maui snared the sun, releasing it only after it promised to move more slowly across the sky.
This archipelago, made up of seven low-lying islands, is home to some of the healthiest coral reefs remaining off North American shores. A unique array of wildlife lives in its marine sanctuary, including the only colony of northern fur seals south of Alaska. Water is everywhere in the smallest of Alaska's national parks—the land challenges the sea with talon-like peninsulas and rocky headlands, while the ocean itself reaches inland with long fjords and hundreds of quiet coves and bays. Kilauea shares the island with another of the world’s most active volcanoes, Mauna Loa, which at 19,000 cubic miles (79,195 cubic kilometers) in volume, makes it the biggest mountain on Earth. Most of Acadia National Park is located on Mount Desert Island, Maine, a wooded piece of land surrounded by bays, harbors, and an island-dotted seascape.
Samoa is also home to miles of pristine beach on the sparsely populated island of Ofu, fringed by a 350-acre (140-hectare) coral reef. At the turn of the 20th century redwoods were threatened by logging, but the trees are now protected for the fascination of future generations. National Geographic built its 125th anniversary issue around this very question last October, calling on writer Lise Funderburg and Martin Schoeller, a renowned photographer and portrait artist, to capture the faces of our nation's multiracial future. These are obviously not Photoshopped projections, but real people, meaning tomorrow's America lives among us now in every "Blackanese," "Filatino," "Chicanese" and "Korgentinian" you meet at the DMV, grocery store or wherever it is you hang out. Complicating things further is the definition of race itself: It has no basis in biology, yet its constructions, functions and mythologies irrevocably shape the world as we know it. Will increased racial mixing finally and permanently redefine how we imagine our racial identities? It's unclear whether they've included same-sex unions in the count, but as currently stated, this number is more than double what it was 25 years ago. 2050 remains decades away, but if these images are any preview, it's definitely a year worth waiting for. Less adventurous visitors can look for the park's “Big Five” animals: moose, caribou, Dall sheep, wolves, and grizzly bears. Aggressive bull moose often spar with their antlers during breeding season while fighting for females, called cows. In summer, the railroad runs between Anchorage and Fairbanks and stops daily at the Denali railroad station. Solitary creatures, the omnivorous bears usually roam by themselves—except for grizzly mothers, usually accompanied by their rambunctious young. After the eggs have incubated for about three months, the mother opens the nest and helps her young out of their shells. Although heavy and slow on land, they can ambush their prey from the water by lunging at speeds of 30 miles (48 kilometers) per hour.
A steady march of population growth and climate change has exacerbated conditions, but it all began with farming, much of it supported by taxpayers in a feverish desire to "settle the West." After irrigation ditches and canals were hewed into the arid ground, farmers planted wheat, then hay. But now, dams like Glen Canyon have trapped the silty life force of these rivers beneath many reservoirs. McClure, who photographed dams, railroads, and river-irrigated agricultural areas in the Colorado River Basin into the mid-19th century.
The humpback chub has neuromast chemoreceptors on its head, allowing the species to smell (rather than see) faraway food in silty water. Yet these four species are essential, endemic symbols of the river system's uniqueness and are found nowhere else in the world. Since first apportioning river water to seven states through the Colorado River Compact in 1922 and subsequent agreements, the basin states' population has increased ninefold. And there are many signs of the conceit of human engineering, from ditches to dams, transforming once pristine rivers throughout the southwest into sportsmen's paradisesa€”in other words, reservoirsa€”frequented by loud motorboats, harboring the gasping Asian carp and invasive quagga mussels, and heavily stocked with sport fishes; and irrigation canals, contaminated with pesticides and agricultural runoff, that largely serve dairy cows (60 percent of the water used for irrigation, or about a third of the river, goes to grow hay and forage crops, according to the Pacific Institute). These reductions in delivery and consumption reflect various successful efficiency and conservation efforts. It is our livelihoods: I have friends who depend on the river for their work as boatmen, fishing guides, defenders of water rights, teachers, photographers, hay growers, farmers, and realtors. He is also the coauthor, with Pete McBride, of The Colorado River: Flowing Through Conflict. The largest population of protected brown bears in North America—some 2,000—is often found fishing in salmon-filled Brooks Falls, a visitor favorite. John island are home to fringing coral reefs—beautiful, complex, and exceedingly fragile communities of plants and animals, upon which St. Only 40 acres (16 hectares) of the park's 100 square miles (260 square kilometers) are above water, creating a marine life sanctuary. The park also includes several beaches where visitors can find solitude even on a crowded day.
Census Bureau let respondents check more than one race for the first time in 2000, and 6.8 million people did so. The latest figures suggest we're getting more comfortable with the idea, or perhaps that we simply give fewer shits than ever before. As a population composed largely of over-educated 20-somethings, our generation is primed and expected to play a major role in populating this projected future America.
Poverty remains a barrier to social mobility and its consequent opportunities to interact with a diverse range of people. Perfect for people like me who refer to Grant Wood's 'American Gothic' as the couple with the pitch fork. Those crops, along with cotton, citrus fruits, 90 percent of the nation's winter vegetables, and almost any other plant imaginable, now consume about 70 percent of the Colorado River Basin's water. The torpedo-shaped and camouflage-backed bonytail chub, rarest of all the native fish, disappeared from the Lower Basin after the construction of Hoover Dam. Continued focus on careful consumption could go a long way toward meeting the water needs of a growing population in an already strained basin. In addition to helping set restoration goals, conservation groups are raising funds to buy water rights from current users. The river itselfa€”a Pliocene relica€”is older than our most precious monuments, older than the Parthenon, Stonehenge, or the Pyramids. McNutt, who was instrumental in the conception and realization of the 10-museum exhibition, will discuss the four years’ preparation for the show, including selecting the images for the show from among the thousands in the National Geographic Archives.
That goes double if you live in a Western state, where people intermarry at higher rates; Hawaii is winning at the moment, with 4 of 10 new marriages identifying as interracial.
Sadly, the inequalities that shape American society as a whole are equally present in interracial relationship patterns. And the tuba-lipped razorback sucker dwells in deep water, avoiding ultraviolet light; while mating, the male flashes its uniquely adapted eyes to reflect ambient UV light and scare off any male competitors.
