In Argentina he learned about mountaineering with barely enough time to prepare before taking part in an expedition to Aconcagua. Still he was able to survive the climb up that treacherous mountain. Later on, he climbed a number of very dangerous mountains, and on all the continents, between the mountains of Nepal, Mexico and Mount Kilimanjaro in Africa, and Mount Kosciuszko in Australia. His detailed description of the ascent on Aconcagua in a book in Spanish became a sort of textbook for mountaineering in Mexico, and other countries across South America.
