Grand Canyon, Arizona, at the confluence of the Colorado River and Little Colorado River. A canyon (from Spanish: cañón; archaic British English spelling: cañon), [1] gorge or chasm, is a deep cleft between escarpments or cliffs resulting from weathering and the erosive activity of a river over geologic time scales.

The Mary Jane Colter Buildings are four structures at Grand Canyon National Park designed by Mary Colter.Built between 1905 and 1932, the four buildings (Hermits Rest (1914), Desert View Watchtower (1932), Lookout Studio (1914), and Hopi House (1905)) are among the best examples of Colter's work, and were influential in the development of an aesthetic for architecture to be used in America's ...
Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, structure stratification, rock exposure, and soil type.Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains ...
At the eastern margin of the Canyon Lands is the Mesa Verde, a huge cuesta that has been deeply dissected by streams. Here in great recesses in the canyon walls are found the ruins of ancient cliff dwellings. East of the Little Colorado River are the brilliantly colored areas known as the Painted Desert. Here the rocks show gorgeous colors in ...
Some sections of a stream or river valleys may have vertically incised their course to such an extent that the valley they occupy is best described as a gorge, ravine, or canyon. Rapid down-cutting may result from localized uplift of the land surface or rejuvenation of the watercourse as a result for example of a reduction in the base level to ...
Although the railroad's operations were on a much smaller scale than those at the Grand Canyon or Yellowstone, its buildings were significant expressions of local park architecture. Both structures were built in a rustic stick style reminiscent of nineteenth century Adirondack camp architecture. The wood-frame buildings were covered with panels ...
Jun. 5—Forty-six years. That's the amount of time that has passed since Anna Sofaer began The Solstice Project. The move came after Sofaer's rediscovery of the Sun Dagger site on Fajada Butte in ...
Even though it is not the deepest canyon in the world (Kali Gandaki Gorge in Nepal is much deeper [16]), the Grand Canyon is known for its visually overwhelming size and its intricate and colorful landscape. Geologically, it is significant because of the thick sequence of ancient rocks that are well preserved and exposed in the walls of the canyon.
