Grand Canyon

It is 6,000 feet.

The south rim offers the panoramic views you most likely have seen in pictures, but it is the most crowded. The north rim offers more trees and shade making it a lot different. For a first time visitor I would go to the south rim because it is the most spectacular and there are also places where you can beat most crowds especially if you hike a couple miles into the canyon.

Leave it as it is. The ages have been at work on it, and man can only mar it.

It's not. They are both valleys but were formed by distinctly different geological processes.

They are alike you just gave the ans. they're both valleys....

The rims in the Canyon are about 2400 meters above sea level, and can get quite cold during the winter season. The all time record for GC Airport is -29 F (!) but that was during a freak cold front.

Freezing temperature occur every winter at the South Rim, and the North Rim closes for months each winter, due to heavy snow.

The Grand Canyon was created mostly by water erosion over millions of years as a river carved out the relatively soft limestone and other soft rock material in the area. Wind erosion played a lesser, but important part. Once the flowing water dug the canyon, the wind gave the canyon its more gnarly look. The erosion continued after the water subsided in these areas, giving the Grand Canyon its present look.

It shouldnt be on a boundary. It is well inside the the North American plate to be on a boundary. Its a canyon not a mountain range.

The Grand Canyon was formed from a river. It eroded away at the rock for millions of years, then dried up to form what we see today.

Yes. Anytime from October through April. The South Rim in particular as it's elevation is about 6,000 feet plus.

It is 1,466 miles according to Google Maps and beynd the range of evem a four day weekend..

The purpose of the Grand Canyon is that it is a deep, giant tourist attraction, created from a river that has formed it over thousands of years. it also provides a good understanding of geographical history, based on the layers of rock that can be seen from erosion. This helps people like geologists learn.

Note quite.

There is a privately operated railway running between the GC and Williams -- which is about thirty miles west of Flagstaff.

a grand canyon is nothing but a big erosion.........

There's water by the river at the bottom of the canyon, so they live close to the water!

Yes. Grandcanyon.com has a list of available helicopter tours on their website, linked below.

It is 545.11 miles according to MapQuest.

• Precambrian Basement Rock - formed 1.8 billion years ago when the continent collided with a group of volcanic islands; intense heat and pressure from the collision formed the metamorphic rock called Vishnu Schist.
• Molten rock from deep within the earth flowed up between the layers of Vishnu Schist to form igneous rock called Zoroaster Granite.
• Bright Angel Shale is found in the flat plateau called the Tonto Platform - formed 515 million years ago when the area was covered by a warm, shallow sea.
  
• Redwall Limestone - 340 million years ago; up to 500 feet thick; formed beneath another shallow sea.
• Supai Group - shales, limestones and sandstones formed 300 million years ago as the coastline rose and fell.
• Hermit Shale - formed 280 million years ago when the area was covered by a broad coastal plain.
• Coconino Sandstone -formed 275 million years ago from coastal sand dunes.
• Kaibab Limestone - formed 270 million years ago; the youngest rock found at the Grand Canyon

The average precipitation in the Grand Canyon is 16.5 inches annually.

Five million people visited the park in 1997, although its buildings, roads, trails and parking areas were designed to accommodate only 1 million a year. I don't know the current number of people visting, but 1997 was I think the largest reported year for visits to the Grand Canyon.

On average, up to 5 million people annually visit the Grand Canyon, which is one of the most visited areas in the United States.

The driving distance between Las Vegas, NV and Grand Junction, CO is approximately 510 miles. The driving time would be approximately 8 hours if you were to travel non-stop in good driving conditions. (The driving time does not take into consideration conditions which may extend trip time such as weather, road work, border crossings and rush hour traffic in urban areas.)
