I fell in love with tall mountains when I was thirteen. My parents and I took the Trans Andean Railway from the pampas of Argentina to Santiago, Chile. It was winter and we were the first train through in a month. High in the mountain peaks of the Andes the train stopped at an army camp. The soldiers were throwing snowballs and laughing. The sky was intense blue and the snow dazzled. The previous eerie silence of the landscape outside of our window was shattered by this moment of human joy set against nature’s cold but beautiful power.
