Sixty million years ago the west side of Bright Angel Fault was lifted higher than the east side, creating the canyon that we now see. The exposed walls of Bright Angel Canyon allow us to see the geological history of the area. Tropical seas, coastal beaches, sand dunes, swamps, lagoons, and Sahara-like deserts are represented by the horizontal layers that are exposed. The upper five layers of stacked rock records 70 million years of rising and falling sea levels. The limestone layers represent shallow sea environments, sandstone layers mean sandy beaches or dunes, while shale layers translate to mud flats, swamps, or coastal plains. This picture of Bright Angel Canyon was taken at sunrise from Bright Angel Point on the North Rim of Grand Canyon National Park, Arizona, USA.

Duck on a Rock Viewpoint is located on the South Rim of the Grand Canyon just east of Yaki Point. Its name comes from the Kaibab formation to the left side of the viewpoint, which some say resembles a duck on a rock. Like every rock formation in the canyon, erosion has worn down the rock to the point where the duck’s bill has all but disappeared. What remains is still a distinctive formation above the canyon. Duck on a Rock Viewpoint is on the East Rim Drive in Grand Canyon National Park, Arizona, USA.

Angels Window is a natural arch formed during the uplift of the Kaibab Plateau. During the uplift, stress and strain caused the limestone to fracture forming vertical joints that intersected the horizontal planes of the rock. Subsequent weathering over time eroded a hole or window in the rock. Angels Window now offers a view of the Colorado River through the hole and the unique experience of walking out over this natural arch to a viewpoint with spectacular views of the canyon below. Angels Window is on the North Rim of Grand Canyon National Park, Arizona, USA.

The Hermit Trail is said to be built in the late 1800's by horsetheives. Prospectors of that era improved the trail. The railroad improved the trail further around 1910 to compete with the Camerons' Bright Angel Trail which charged a toll at the time. The Hermit Trail drops from the South Rim in Grand Canyon National Park, Arizona, USA.

The Grand Canyon is a steep-sided canyon carved by the Colorado River. It is 277 miles long, up to 18 miles wide and attains a depth of over a mile. The canyon and adjacent north and south rims are contained within Grand Canyon National Park, the Kaibab National Forest, Grand Canyon-Parashant National Monument, the Hualapai Indian Reservation, the Havasupai Indian Reservation and the Navajo Nation. In the Grand Canyon the carving of the Colorado River has exposed nearly two billion years of the earth's geological history and created some stunning scenery. This sunset scene was photographed from Mather Point in Grand Canyon National Park, Arizona, USA.

The Rock Squirrel (Spermophilus variegatus) is fairly large ground squirrel but can also be seen climbing boulders, rocks and trees. It is typically 17-21 inches long, with a bushy tail up to 8 inches long. Rock squirrels are grayish-brown, with some patches of cinnamon color. They have a light-colored ring around their eyes and pointed ears that project well above their heads. In the northern reach of their habitat, rock squirrels hibernate during the colder months of the year. In southern areas, rock squirrels may not hibernate at all. The diet of the rock squirrel is predominantly herbivorous, consisting mostly of leaves, stems and seeds. They may also eat some insects and other small animals. Because of high human visitation, rock squirrels have become the most dangerous animals at the national parks of the American Southwest. Rock squirrels attack more tourists at the Grand Canyon than any other wild animal. Attacks have become so common that park rangers have begun warning tourists about the dangers. This rock squirrel was photographed at Yavapai Point in Grand Canyon National Park, Arizona, USA.

The Kaibab Plateau north of the Grand Canyon, at 8000 feet above sea level, supports a forest similar to that found in Canada. The cool moist climate is in sharp contrast to the deserts below. Spruce, fir and aspen populate these higher elevations and surround beautiful mountain meadows. Most destinations at the Grand Canyon are very popular tourist destinations. The hike to Cape Final is one place where one can find solitude. This view of the Grand Canyon was photographed from Cape Final on the North Rim of Grand Canyon National Park, Arizona, USA.

The Desert View Watchtower is a 70-foot high stone building located on the South Rim within Grand Canyon National Park in Arizona, USA. The four-story historic structure, completed in 1932, was designed by American architect Mary Colter who also created and designed many other buildings in the Grand Canyon vicinity including Hermit's Rest and the Lookout Studio.

The American Bison (Bison bison) is a North American species of bison that once roamed the United States in vast herds. The bison is an iconic symbol of the western frontier and is the national mammal of the United States. Biologists estimate that 30 to 60 million of the animals once roamed North America. Over the years they were almost hunted out of existence. By the 1880's only a few were left and early conservationists stepped in to save them from extinction. The House Rock bison herd in Arizona represents an unusual chapter in the history of bison. In the early 1900s, a man named Charles Jesse Jones moved a herd of bison by train to southern Utah, then drove them to the House Rock Valley on the Kaibab Plateau, a grassy forested expanse near the Grand Canyon’s North Rim. Eventually Jones abandoned the bison and they became a free-ranging herd. Hunting pressure made the animals wary and they looked for safe havens away from the House Rock Valley. Within the last decade the herd began to stay within the nearby national park year-round where they are safe from hunting. The herd, which has a high percentage of cattle genes, is now estimated to be about 400 to 600 bison. This bison was photographed in a grassy meadow just south of the entrance to Grand Canyon National Park, Arizona, USA.
