Uses the example of Yosemite Valley in California to describe valleys, which are the lowlands between hills or mountains. Cities and towns are often built in valleys and streams or rivers typically run through them. While valleys slope gently, canyons are deep and narrow. They can be located in moun…

The deepest canyon in the world is one of the most famous US tourist attractions. And it's respectively called the Grand Canyon of Colorado Plateau: "grand" means "big, magnificent, enormous, great" and so on and so forth. The Grand Canyon was added to the famous UNESCO World Heritage List in 1979. The list itself was created in 1972, which makes the Grand Canyon one of its first entries.

The width of the canyon ranges between 20 and 6 kilometers. However, there is one spot where it narrows down to 800 meters. As it narrows down, the walls pull closer together reaching 100 meters gap at the rock bottom.

The canyon has been in the making for 10 million years. 4 different geological eras of Earth are represented in the canyon. Underground forces pushed the Colorado River bed up, forcing the water to gradually cut into the plateau and wash out the canyon's soft rocks. This process is still active: the Colorado River washes out about half a million tons of rock a day, so that even the hardest granite walls of the canyon surrender about quarter of a millimeter each year to this "filing".

The canyon doesn't look like a long narrow hole in the ground at all. It's randomly filled with rocks and cliffs of different shapes: giant pagodas, pyramids, towers, fortified walls and other incredible formations made by nature... Having been thoroughly studied by modern scientists, and being the most famous US tourist attraction, the Grand Canyon receives a lot of visitors. Many of the Grand Canyon cliffs now have their own original names. Such as, Vishnu Temple, Shiva Temple, and Wotan's Throne.

Of course these names are fairly new. Native Americans knew about Grand Canyon thousands of years ago and probably gave those rocks different names. However there is no written evidence of it, only petroglyphs.

The modern human history knows two Grand Canyon discoveries: first one happened in 1540 when a group of Spanish soldiers stumbled upon it in their search for gold. Greedy Spaniards found no gold and no water there, and admiring Grand Canyon scenery wasn't in their plans, so they left and never mentioned this location.

After this incident Europeans have forgotten about the canyon for several centuries. In 1869 professor John Wesley Powell organized first scientific expedition to Grand Canyon. Powell explored and described the canyon. By the way, another US tourist attraction was named after him - Lake Powell.

But let us go back to our canyons. Nowadays a trip to Grand Canyon is on top of the list for almost every tourist coming to the USA. And not so long ago (in the 1940th and 1950th) one could take a picture of the Grand Canyon without actually going there. The thing is that many passenger airlines, flying in this area, intentionally took a scenic route so their passengers could admire the view of the Grand Canyon. It was also common for pilots to make several circles and roll the plane to give the passengers the best view. This was permitted until the collision of 2 passenger aircrafts in 1956. Since then the "dancing" over the Grand Canyon has been prohibited.

Nevertheless, there are several other options for those who want to see the Grand Canyon landscapes: you can take a trip to the USA; or you can enjoy our virtual aerial photo tour. The length of the Grand Canyon is about 450 kilometers. Earlier we published the aerial panoramas' shot at the beginning of the Grand Canyon (link to the Horseshoe), and now we would like to show the West end of the Grand Canyon - which is approximately 100 kilometers from Las Vegas. Let's see!

Tuve el privilegio de conocer ese hermoso lugar hace ya muchos años, en 1980.
El panorama verdaderamente es sensacional.
Las imágenes quedaron grabadas en mi mente por siempre. Una de las maravillas de la Naturaleza como nuestras Cataratas, Nuestro Ventisquero Perito Moreno, Nuestra Antártida, etc.
Otro Panorama similar pude observar en el Cañon de Chicamocha, en cercanáias de Bucaramanga en Colombia.

My breath is taken away by Mother earth each day.
Her treasure is this Earth that we explore each day. To enjoy for a life time each moment you see. Our earth takes our breath away and opens up our senses you see. So we can enjoy and live and love for eternity.

Thank you for such a great way to start the day. I look forward to all that you give.

Imagine you're staring at an electronic device... okay good!

Now imagine you are surrounded by the Grand Canyon...or Cataract Canyon... or Desolation Canyon...

If it's hard to do, then you may be suffering from symptoms of Nature Deficit Disorder - it's simply been too long since you immersed yourself in wild places. We can help!

Long Term Fix: There's nothing like the real thing. You'll just have to book a trip for this summer! If you have already, good thinking! Share this remedy with anyone you know that needs more teeter in their totter. We're talking about literally surrounding yourself with nature and wild places. Field tests have proven that there are life-long benefits associated with this kind of treatment. It's that good!

Short Term Fix: To alleviate the effects of Nature Deficit Disorder during the long winter months when we are away from the river and Canyons we love, we have developed "360 Degree Virtual Nature Teleportation Portals". Some call them "Magic Rectangles". There are more than a dozen views to peek at in each trip. Use your computer mouse or tablet finger device to literally "look around" the canyons. It's pretty amazing.
