The resulting Grand Canyon Supergroup of sedimentary units is composed of nine varied geologic formations that were laid down from 1.2 billion and 740 million years ago in this sea. [11] Good exposures of the supergroup can be seen in eastern Grand Canyon in the Inner Gorge and from Desert View, Lipan Point and Moran point. [12] [note 1]
The Greenland ice sheet is 3 kilometers (1.9 mi) thick and broad enough to blanket an area the size of Mexico.The ice is so massive that its weight presses the bedrock of Greenland below sea level and is so all-concealing that not until recently did scientists discover Greenland's Grand Canyon or the possibility that Greenland might actually be three islands.

[citation needed] Today, the Grand Canyon is a part of Region 8, also known as the Lower Colorado Basin. [16]
Grand Canyon covered with snow. Temperatures vary wildly throughout the year, with summer highs within the Inner Gorge commonly exceeding 100 °F (38 °C) and winter minimum temperatures sometimes falling below zero degrees Fahrenheit (−18 °C) along the canyon's rims. [108]
The geologic temperature record are changes in Earth's environment as determined from geologic evidence on multi-million to billion (10 9) year time scales. The study of past temperatures provides an important paleoenvironmental insight because it is a component of the climate and oceanography of the time.
The Grand Canyon, a Wonder of the World, is about 80 miles (130 km) northwest of Flagstaff. [39] The first stagecoach tours to the Grand Canyon from the city began running from the Bank Hotel in 1892. [8] In 2000, about 5 million people visiting the Grand Canyon also visited Flagstaff.
