It was raining and blustery and just above freezing as I shoved another translucent, blue gummy bear into my mouth. I was sitting at the top of Dead Woman’s Pass, 13,828 feet above sea level, waiting for the rest of my group to catch up and desperately in need of carbs. For a windswept, bedraggled hiker, I was in surprisingly good spirits. I watched the rain drip gingerly off my hooded poncho like a curious ant hiding beneath a blade of grass to stay dry as I gazed out at the misty cloud forest below, daydreaming about coca leaves and crimson orchids hidden in the deep crevices of towering trees. I had just completed the most difficult section of the Inca Trail in a downpour with a full pack on, and I was incandescently happy.
