Title: Chihuahua (state)
Passage: The main mountain range in the state is the Sierra Madre Occidental reaching a maximum altitude of 10,826 ft (3,300 m) known as Cerro Mohinora. Mountains account for one third of the state's surface area which include large coniferous forests. The climate in the mountainous regions varies Chihuahua has more forests than any other state in Mexico making the area a bountiful source of wood; the mountainous areas are rich in minerals important to Mexico's mining industry. Precipitation and temperature in the mountainous areas depends on the elevation. Between the months of November and March snow storms are possible in the lower elevations and are frequent in the higher elevations. There are several watersheds located in the Sierra Madre Occidental all of the water that flows through the state; most of the rivers finally empty into the Río Grande. Temperatures in some canyons in the state reach over 100 °F in the summer while the same areas rarely drop below 32 °F in the winter. Microclimates found in the heart of the Sierra Madre Occidental in the state could be considered tropical, and wild tropical plants have been found in some canyons. La Barranca del Cobre, or Copper Canyon, a spectacular canyon system larger and deeper than the Grand Canyon; the canyon also contains Mexico's two tallest waterfalls: Basaseachic Falls and Piedra Volada. There are two national parks found in the mountainous area of the state: Cumbres de Majalca National Park and Basaseachic Falls National Park.

Title: Hells Canyon
Passage: Hells Canyon is a 10 - mile (16 km) wide canyon located along the border of eastern Oregon, eastern Washington and western Idaho in the United States. It is part of the Hells Canyon National Recreation Area and is North America's deepest river gorge at 7,993 feet (2,436 m).
Title: Grand Canyon
Passage: The Grand Canyon is a river valley in the Colorado Plateau that exposes uplifted Proterozoic and Paleozoic strata, and is also one of the six distinct physiographic sections of the Colorado Plateau province. It is not the deepest canyon in the world (Kali Gandaki Gorge in Nepal is much deeper). However, 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. These rock layers record much of the early geologic history of the North American continent.
Title: Agus River
Passage: Agus River is a river that flows for from Lanao Lake to Iligan Bay, Philippines. It cuts through the provinces of Lanao del Sur and Lanao del Norte. Settlements along the banks of the river include the City of Marawi, the Municipality of Linamon and the City of Iligan. It separates into two channels as it drains to Iligan Bay; one going over the Maria Cristina Falls while the other supplies the Tinago Falls. The river descends for about from its source as it flows for before draining to the sea. The river is relatively shallow as it is only deep in some areas. The Agus River's watershed spans about 11,320.00 hectares. In 1992, the National Power Corporation financed the reforestation of the Lake Lanao-Agus River watershed, planting over 1500 hectares of "Acacia mangium", "Durio zibethinus" and other indigenous trees. It has a discharge of about and flows from a narrow depression off the northwestern rim of the lake and flows over a basalt rock formation. The canyon carved by the river suggests a short erosional period.
Title: Owens River Gorge
Passage: The Owens River Gorge is a steep 10 mi (16 km) canyon on the upper Owens River in eastern California in the United States. The canyon is located at the eastern edge of the Sierra Nevada mountains in southern Mono County, along the stretch of the river where it exits the Long Valley near its source and enters the north end of Owens Valley. The gorge is a popular destination for rock climbing.
Title: Tiputini River
Passage: The Tiputini River is a tributary of the Napo River in eastern Ecuador. It is the first major, navagable river south of the Napo and forms the northern border of Yasuni National Park. Unlike the Napo, the Tiputini has a relatively deep, narrow channel carved deep into the clay of the Amazon Basin, and it often fluctuates in depth by several meters from day to day.
Title: Rock carvings at Møllerstufossen
Passage: The Rock carvings at Møllerstufossen in Nord-Sinni in Nordre Land municipality in Oppland county of Norway comprise several carvings of moose and one other animal. The site covers about 20 m². The largest figure measures about 90 cm across. The figures are carved with deep and wide strokes and are easy to spot.
Title: Grand Canyon
Passage: The Grand Canyon (Hopi: Ongtupqa; Yavapai: Wi: kaʼi: la, Navajo: Tsékooh Hatsoh, Spanish: Gran Cañón) is a steep - sided canyon carved by the Colorado River in Arizona, United States. The Grand Canyon is 277 miles (446 km) long, up to 18 miles (29 km) wide and attains a depth of over a mile (6,093 feet or 1,857 meters).
Title: Oxwick
Passage: Oxwick is a hamlet in the English county of Norfolk. It lies close to the source of the River Wensum and lies one mile south of the village of Colkirk .
Title: Byers Canyon
Passage: Byers Canyon is a short gorge on the upper Colorado River in Grand County, Colorado in the United States. The canyon is approximately 8 miles (13 km) long and is located in the headwaters region of the Colorado between Hot Sulphur Springs and Kremmling. U.S. Highway 40 passes through the canyon between Hot Sulphur Springs and Kremmling. The Union Pacific Railroad's Moffat Route also travels through the short canyon.
Title: Grand Canyon National Park
Passage: Grand Canyon National Park, located in northwestern Arizona, is the 15th site in the United States to have been named a national park. The park's central feature is the Grand Canyon, a gorge of the Colorado River, which is often considered one of the Wonders of the World. The park, which covers 1,217,262 acres (1,901.972 sq mi; 4,926.08 km) of unincorporated area in Coconino and Mohave counties, received more than six million recreational visitors in 2017, which is the second highest count of all American national parks after Great Smoky Mountains National Park. The Grand Canyon was designated a World Heritage Site by UNESCO in 1979.
Title: Minnie Maud
Passage: Minnie Maud is the name of a creek and canyon in eastern Utah that is noted as the western starting point of the Nine Mile Canyon petroglyphs section. Minnie Maud Creek is a stream whose headwaters begin where the Western Tavaputs and Wasatch Plateau meet the Uinta Mountains. The creek flows through a comparatively narrow valley and has limited irrigation possibilities. It has a general easterly course and merges with Nine Mile Creek. Minnie Maud Creek drains into Nine Mile Creek which reaches the Green River in Desolation Canyon.
Title: Thompson River (Missouri)
Passage: It rises in the agricultural lands of Adair County, Iowa, a few miles northeast of Greenfield. The river initially flows east then bends south, passing Macksburg and Davis City and crossing Interstate 35. It then flows into Missouri, where much of its course is channelized. The Weldon River joins at the town of Trenton, the largest settlement along the Thompson River. Below Trenton, the Thompson meanders south for another , joining the Grand River just north of Utica in Livingston County.
Title: Gore Canyon
Passage: Gore Canyon is a short isolated canyon on the upper Colorado River in southwestern Grand County, Colorado in the United States. The steep and rugged canyon, approximately 3 miles (5 km) long, was carved by the river as it passed the northern end of the Gore Range southwest of Kremmling. The Colorado descends from approximately to approximately over the length of the canyon. The steep walls ascend approximately on either side. The canyon effectively marks the southwestern end of the Middle Park basin in north central Colorado.
Title: Chihuahua (state)
Passage: Although Chihuahua is primarily identified with the Chihuahuan Desert for namesake, it has more forests than any other state in Mexico, with the exception of Durango. Due to its variant climate, the state has a large variety of fauna and flora. The state is mostly characterized by rugged mountainous terrain and wide river valleys. The Sierra Madre Occidental mountain range, an extension of the Rocky Mountains, dominates the state's terrain and is home to the state's greatest attraction, Las Barrancas del Cobre, or Copper Canyon, a canyon system larger and deeper than the Grand Canyon. On the slope of the Sierra Madre Occidental mountains (around the regions of Casas Grandes, Cuauhtémoc and Parral), there are vast prairies of short yellow grass, the source of the bulk of the state's agricultural production. Most of the inhabitants live along the Rio Grande Valley and the Conchos River Valley.
Title: Grand Canyon
Passage: Nearly two billion years of Earth's geological history have been exposed as the Colorado River and its tributaries cut their channels through layer after layer of rock while the Colorado Plateau was uplifted. While some aspects about the history of incision of the canyon are debated by geologists, several recent studies support the hypothesis that the Colorado River established its course through the area about 5 to 6 million years ago. Since that time, the Colorado River has driven the down - cutting of the tributaries and retreat of the cliffs, simultaneously deepening and widening the canyon.
