Americas
The largest mountain ranges are the Andes and Rocky Mountains. The Sierra Nevada and the Cascade Range reach similar altitudes as the Rocky Mountains, but are significantly smaller. In North America, the greatest number of fourteeners are in the United States, and more specifically in the U.S. state of Colorado. The highest peaks of the Americas are located in the Andes, with Aconcagua of Argentina being the highest; in North America Denali (Mount McKinley) in the U.S. state of Alaska is the tallest.
Tyler Armstrong
After reaching the top of Kilimanjaro, Armstrong started to look for a new challenge, which he found in Argentina. Mount Aconcagua was his new target, and being the youngest person to climb it was his goal. As a training exercise, he climbed Mount Baldy on August 17, 2013, as part of the fifth annual Climb to Cure Duchenne.
After months of preparation, Armstrong was ready for his journey to Argentina. On December 7, he left the United States. He spent his first couple of days trying to get a special permit because the minimum age for climbing Mount Aconcagua is 14. After obtaining a special permit, Armstrong started his climb on December 15, taking the Polish Glacier Traverse Route. On December 24, 2013, Armstrong reached the top and broke the record for being the youngest person to climb Mount Aconcagua, at the age of 9, making headlines all over the world.
