9 year old, Tyler Armstrong, has become the youngest person in history to climb and reach the top of Argentina’s Aconcagua mountain, which is the tallest peak in the Western Hemisphere.

Armstrong, from California, reached the peak of the mountain with his father Kevin and a Tibetan sherpa, according to The Associated Press. They made it to the top of the summit on Christmas Eve.

Armstrong said that his most memorable moment of the trip was seeing his father reach the summit. Kevin Armstrong has accompanied Tyler in every climb he has made.

Kevin Armstrong said that, "Most people think we as parents are pushing Tyler to do this, when it's completely the opposite. I wouldn't climb it if I didn't have to, but my wife makes me do it to keep watch on him.”
At the young age of 7, Armstrong scaled Mount Whitney in the United States. Just last he climbed Mount Kilimanjaro.

Armstrong and his father set out on the adventure on December 7, according to NBC. They made the climb to raise awareness and money for Duchenne muscular dystrophy. This disease affects approximately 1 in 3,600 young boys.

The climb has claimed more than 100 lives. Only 30 percent of the 7,000 people who attempt the climb each year actually make it, but that meant nothing to this young boy.

Tyler is set to be back in the U.S. on January 5, 2014.
