Amazing Places on the Earth, Part 1

The Great Blue Hole of Belize

The Great Blue Hole is a large underwater sinkhole off the coast of Belize. It lies near the center of Lighthouse Reef, a small atoll 70 kilometres (43 mi) from the mainland and Belize City. The hole is circular in shape, over 300 metres (984 ft) across and 124 metres (407 ft) deep. It was formed during several episodes of Quaternary glaciation when sea levels were much lower - the analysis of stalactites found in Great Blue Hole shows that formation has taken place 153,000, 66,000, 60,000, and 15,000 years ago. As the ocean began to rise again, the caves were flooded. The Great Blue Hole is a part of the larger Belize Barrier Reef Reserve System, a World Heritage Site of the United Nations Educational, Scientific and Cultural Organization (UNESCO).

Mount Roraima

Mount Roraima (also known as Monte Roraima in Spanish and Portuguese), is the highest of the Pakaraima chain of tepui plateau in South America. First described by the English explorer Sir Walter Raleigh in 1596, it's 31 km2 summit area is defended by 400-metre-tall cliffs on all sides. The mountain includes the triple border point of Venezuela, Brazil and Guyana.

Mount Roraima lies on the Guiana Shield in the southeastern corner of Venezuela's 30000 km2 Canaima National Park forming the highest peak of Guyana's Highland Range. The tabletop mountains of the park are considered some of the oldest geological formations on Earth, dating back to some two billion years ago in the Precambrian.

Iguazu Falls

Iguazu Falls, Iguassu Falls, or Iguaçu Falls (Portuguese: Cataratas do Iguaçu [kataˈɾatɐz du iɡwaˈsu]; Spanish: Cataratas del Iguazú [kataˈɾataz ðel iɣwaˈsu]; Guarani: Chororo Yguasu [ɕoɾoɾo ɨɣʷasu]) are waterfalls of the Iguazu River located on the border of the Brazilian State of Paraná and the Argentine Province of Misiones. The falls divide the river into the upper and lower Iguazu. The Iguazu River originates near the city of Curitiba. It flows through Brazil for most of its course. Below its confluence with the San Antonio River, the Iguazu River forms the boundary between Brazil and Argentina.

Antelope Canyon

Antelope Canyon is the most-visited and most-photographed slot canyon in the American Southwest. It is located on Navajo land near Page, Arizona. Antelope Canyon includes two separate, photogenic slot canyon sections, referred to individually as Upper Antelope Canyon or The Crack; and Lower Antelope Canyon or The Corkscrew.

The Navajo name for Upper Antelope Canyon is Tsé bighánílíní, which means "the place where water runs through rocks." Lower Antelope Canyon is Hazdistazí (advertised as "Hasdestwazi" by the Navajo Parks and Recreation Department), or "spiral rock arches." Both are located within the LeChee Chapter of the Navajo Nation.
