Monument Valley is located on the southern border of Utah with northern Arizona. The valley lies within the range of the Navajo Nation Reservation, and is accessible from U.S. Highway 163. The Navajo name for the valley is Tsé Bii' Ndzisgaii (Valley of the Rocks).The area is part of the Colorado Plateau. The floor is largely Cutler Red siltstone or its sand deposited by the meandering rivers that carved the valley. The valley's vivid red color comes from iron oxide exposed in the weathered siltstone. The darker, blue-gray rocks in the valley get their color from manganese oxide.

Havasu Falls, one of the four waterfalls of the Havasupai Indian Reservation, is located near the village of Supai, Arizona. It is the second of four falls on Havasu Creek, which empties into the Grand Canyon on the Colorado River. The water of Havasu Creek has a bluish green tint due to the heavy lime content of the water. The fall is forked and looks like two falls when the river is flowing heavily.

A panoramic view of Horseshoe Bend, a horseshoe-shaped meander in the Colorado River, from State Route 89. It is located approximately 4 miles (6.4 km) south of Page, Arizona, slightly downstream from the Glen Canyon Dam and Lake Powell.

An HDR image of Upper Antelope Canyon, Page, Arizona. Antelope Canyon is the most-visited and most-photographed slot canyon in the Southwestern United States. It was formed by erosion of Navajo Sandstone, primarily due to flash flooding and secondarily due to other sub-aerial processes. Photography within the canyons is difficult due to the wide exposure range (often 10 EV or more) made by light reflecting off the canyon walls.

Glen Canyon, in southeastern and south central Utah and northwestern Arizona within the Vermilion Cliffs area, was carved by two rivers, the Colorado River and the San Juan River.A reservoir, Lake Powell, was created by the Glen Canyon Dam. Lake Powell emerged from a struggle over damming Dinosaur National Monument.

The Central Arizona Project Aqueduct is a diversion canal in Arizona in the United States. The aqueduct diverts water from the Colorado River from Lake Havasu City into central and southern Arizona. The Central Arizona Project is a multipurpose water resource development and management project that was designed to provide water to nearly one million acres (4,000 km²) of Indian and non-Indian irrigated agricultural land areas as well as municipal water for several Arizona communities.

This photograph of Canyon de Chelly, showing 'seven riders on horseback and dog', is one of his most celebrated images from The North American Indian. Canyon de Chelly is a National Park located in northeast Arizona, United States. Founded April 1, 1931, it preserves artifacts of the early Southwest Indian tribes that lived in the area, including the Navajo. The cliffs of the canyon are pockmarked with hand carved caves — the ruins of former villages.

Petrified wood, such as this sample found in Petrified Forest National Park, Arizona, United States, is a fossil wood where all the organic materials have been replaced with minerals, while retaining the original structure of the wood.

A petrified log in Petrified Forest National Park, located in northeastern Arizona, US. The pieces of wood found in the park are mostly of the extinct species Araucarioxylon arizonicum. The logs were buried under volcanic ash, which was the source of the silica that helped to permineralize the buried logs, replacing wood with silica, colored with oxides of iron and manganese.
