Exploring Grand Canyon

"For each man sees himself in the Grand Canyon - each one makes his own Canyon before he comes, each one brings and carries away his own Canyon."

The quote seen inside the viewing room of the visitors' center is from Carl Sandburg. Carl Sandburg was a poet and and three-time Pulitzer awardee who mused on the Grand Canyon.

After  the United States acquired Arizona, along with California, Nevada, New Mexico and Wyoming following a brief war with Mexico that ended in 1848, Grand Canyon was designated as a forest reserve by President  Benjamin Harrison. 

The American Antiquities Act of 1906 subsequently made the Grand Canyon Forest Reserve  into Grand Canyon National Monument by President Theodore Roosevelt. 

Grand Canyon became the national park of today three years after the enactment of the National Park Service Act by President Woodrow Wilson. 

The Grand Canyon is both a high desert and an inverted forest. It showcases  hundred of millions to almost two

billion years of global warming and climate change for believers and rock formation for geologists. 

However, when the glaciers over the Colorado Plateau melted some 11,000 years ago, it was not because of the greenhouse effect of carbon gases brought about by mankind's collective farting or burning up fossil fuels. 

Geologic studies of the Grand Canyon began with John Strong Newberry in 1858.

Glaciers melted and weather systems changed in the last 2 billion years not because of the heat in the atmosphere bouncing back to the earth's surface. 

One scientific theory used to understand glacial and interglacial periods like the  Pleistocene era or the Ice Age is on the premise that the earth has been flip-flopping every several hundred thousand years. 

Not that the earth have changed from being a Republican into a Snowflake 17 times in the last 2 billion years. 

The theory that the earth tilts on orbit gradually until the sun shines more on the North Pole and less on Ecuador explains more about interglacial periods. The result might have been climate change that melted glaciers during the Pleistocene Era or Ice Age.

The interglacial periods that helped transform Grand Canyon  provides a climate change perspective that is not about aerosol hairsprays and refrigerants accumulating as chlorofluorocarbons in the atmosphere resulting to the greenhouse effect. 

Grand Canyon is a living result of scientific phenomena  that evolved in between interglacial periods for the last 2 billion years long before authors of the book of Genesis came up with the creation theory and Al Gore promoted the global warming crap.

Colorado River once upon a time ran through the Colorado Plateau Province which had elevation of 5,000 to 13,000 above sea level until stream erosions and volcanic activities carved the plateau into the Grand Canyon of today. 

Millions of years of arid weather and high temperatures has created layers and layers or rock formation that form  the walls of the Grand Canyon.   

"I believe in evolution. But I also believe, when I hike the Grand Canyon and see it at sunset, that the hand of God is there also."

John McCain
