The first recorded sighting of the Grand Canyon by a European was in 1540, García López de Cárdenas from Spain. The first scientific expedition to the canyon was led by U.S. Major John Wesley Powell in the late 1860s\nJames Ohio Pattie, with a group of American trappers and mountain men were probably the next Europeans to reach the Canyon in 1826, although there is little documentation to support this.\n\nJacob Hamblin (a Mormon missionary) was sent by Brigham Young in the 1850's to locate easy river crossing sites in the Canyon. Building good relations with local Native Americans and white settlers, he discovered Lee's Ferry in 1858 and Pierce Ferry (later operated by, and named for, Harrison Pierce) - the only two sites suitable for ferry operation.\n\nIn 1857, the U.S. War Department asked Lieutenant Joseph Ives to lead an expedition to assess the feasibility of an up-river navigation from the Gulf of California. Also in a stern wheeler steamboat "Explorer", after two months and 350 miles of difficult navigation, his party reached Black Canyon some two months after George Johnson. The "Explorer" struck a rock and was abandoned. Ives led his party east into the Canyon - they were the first Europeans to travel the Diamond Creek drainage and traveled eastwards along the South Rim. James White (this links to a disambiguation page that does not contain a link to this James White yet!)\nIn 1956 the Grand Canyon was the site of America's worst commercial aviation disaster at the time.\n\nOn the morning of June 30, 1956, a TWA Lockheed Super Constellation and a United Airlines Douglas DC-7 departed Los Angeles International Airport within three minutes of one another on eastbound transcontinental flights. Approximately 90 minutes later, the two propeller-driven airliners collided above the canyon while both were flying in unmonitored airspace.\n\nThe wreckage of both planes fell into the eastern portion of the canyon, on Temple and Chuar buttes, near the confluence of the Colorado and Little Colorado rivers. The disaster killed all 128 passengers and crew members aboard both planes. This accident lead to the instutuion of high altitude flightways and positive control by enroute ground controllers

The oldest rock at the bottom of the Grand Canyon is indeed the Vishnu Schist, however the first answer given is wrong about the age. It is 2 BILLION years old. The canyon itself is believed to have been formed over the past 5 or 6 million years by erosion of much older rocks that range in age from 250 million years at the top of the canyon to the 2 billion year old rock at the bottom.

The Grand Canyon cuts across the upper northwestern edge of Arizona (just below the border with Utah).  The main portion of the canyon is over 250 miles long and runs from near Lake Powell on east to Lake Mead on the west.\n\nThe most famous portion (and the area with the lodges) is near the middle.  There is a small park service-ran community on the South Rim with numerous lodges and a smaller lodge on the North Rim that is only open in summer.  The North Rim is much higher elevation and thus cooler and gets snow in the winter (it is also much less developed).  \n\nThe closest towns to the South Rim are Flagstaff and Williams, Arizona along I-40 (about 90 miles away).  The nearest town to the North Rim lodge is Kanab, Utah (also about 90 miles).  It is about a 4 hour drive from Phoenix, Arizona to the South Rim and about a 6-7 hour drive from Las Vegas to the North Rim.

They bring fans together, are a form of entertainment, much like a TV show or shopping, and are so organized (standings, statistics, final scores) - people subconsciously seek this organization within their hectic lives. It sounds cheesy but its true. I HIGHLY recommend the book "The Meaning of Sports" by Michael Mandelbaum. Sports are a form of diversion from the burdens of daily life. It is like an unscripted drama - the outcome of each game and each season is unknown by all. Some say "it's only a game", but is the Grand Canyon "only a hole?" Absolutely not

This sort of depends on what you mean by natural wonder, but there are many.\n\nOne of my favourite is the scablands of the Western U.S. centering about the Snake River Canyon. These were carved out by a huge catastrophic flood that occurred at the end of the last glacial maximum. As the Laurentian continental glaciers receded north, one limb that had been blocking a giant lake gave way, and the water rushed all the way from about Montana to the Pacific. I'm recalling all of this from memory.

there is a place in Idaho called Hells Canyon.

Think of the Grand Canyon under water.   Huge rips in the ocean floor that are very very deep and dark and dangerous - possibly filled with the most unusual lifeforms never seen by man.

Petrified Forest.\n\nIt is a National Park in northeastern Arizona that contains one of the largest collections of petrified trees in the world (formed by the process described in your question).  It is right next to the Painted Desert - a area of multi-colored ridges and hills.

The Colorado River that originates in the Rocky Mountains and flows through the Grand Canyon. The Hoover Dam forms a lake known as Lake Mead that extends upstream as far as the mouth of the Grand Canyon. The Colorado River eventually drains into the Sea of Cortez (Gulf of California) in Mexico. \nhttp://www.desertusa.com/colorado/coloriv/du_coloriv.html\n\nThere are other rivers named the Colorado River, one of which flows through Austin, Texas and empties into the Gulf of Mexico.

Grand Canyon, Arizona, north of Flagstaff.  That's what it's called, although I'm unsure of whether it is an actual city.

I don't know what your teacher has told you, but erosion was a major factor in the formation of the Grand Canyon.  Water flowing through the area over millions of years did an amazing job.

I think they are names of tour boats or rafts in the grand canyon.
