George Washington was a leader of the Continental Army in the American Revolution, and was the first to become U.S. president.
The Himalayas and the Tibetan Plateau to the north have risen very rapidly. In just 50 million years, peaks such as Mt. Everest have risen to heights of more than 9 km. The impinging of the two landmasses has yet to end. The Himalayas continue to rise more than 1 cm a year -- a growth rate of 10 km in a million years!
What is more certain is Kilimanjaro claim to be the tallest free-standing mountain in the world (ie one that is not part of a mountain range: Nanga Parbat is at the western end of the Himalaya range, while McKinley is part of the Alaska range). And this, we think, is very important.
