ALPINIST KARLA WHEELOCK’S CONNECTION to nature started after joining the Girl Scouts at age 5. By the time she was 25, she had already scaled Mexico’s highest summits: Popocatépetl, Iztaccíhuatl and Citlaltépetl.

That’s when she decided to go after the Seven Summits challenge: climbing the highest mountain on each of the seven continents. At the time, only an American businessman had accomplished the task. She started by peaking Aconcagua (the highest peak outside of Asia at 22,838 feet) in Argentina, and then went on in 1999 to make history as the first Mexican and Latina woman to make it to the top of Mount Everest. By 2005, she had completed the challenge.

Karla now continues to hike and climb, and she even led the first group of Latino explorers to Antarctica in 2010. Read the full article on Karla’s adventures in Remezcla or watch the video above to hear more of her incredible story.
